1 Introduction
1.3 CARESCAPE R860
The CARESCAPE R860 combines sophisticated technology and an intuitive
user interface. Icons represent configurable views of past (historical trends),
present (patient status), and future patient needs (clinical decision support).
The ventilator consists of a display, ventilator unit, cart with AC outlet (optional),
EVair compressor (optional), and module bay with gas module (optional).
A wide selection of performance options give the user full control of the system
configuration. This ventilator is a complete system featuring patient ventilation,
monitoring, and the capability of interfacing with central monitoring. Full
touchscreen capability allows the user to quickly and easily access patient
information and procedures.
This ventilator supports adult, pediatric, and neonatal patients. The basic
ventilator is equipped with adult and pediatric patient type software. The
neonatal software option can be added or the ventilator can be set to enable
the Neonatal-Only option. When the Neonatal-Only option is set, the ventilator
is only intended to be used for neonatal patients and will not be able to enter
the adult or pediatric patient types. This ventilator comes with standard
ventilation modes as well as a purchasable neonatal patient option, ventilation
modes, and clinical decision support features.
Configurations available for this product depend on local market and standards
requirements. Illustrations or photos in this manual may not represent all
configurations of the product. This manual does not cover the operation of
every accessory. Refer to the accessory documentation for further information.
The assembly of the ventilator system and modifications during its service life
require evaluation to ensure the requirements of IEC 60601-1:2005 are met.

2.1 Pneumatic operation
For a complete diagram of the pneumatic system, see "11.1 Pneumatic
system".
The ventilator requires medical-grade oxygen (O2) and medical-grade Air
sources ranging from 2.4 to 6.5 bar (35 to 94 psi). See "A.1 Medical-Grade Air
Recommended Specifications" for additional information regarding medicalgrade gases. Additional filtering will not be necessary if supplied gases are
medical grade. If the supply gas does not meet specifications, see "A Medical
Grade Gases" for information regarding risks and recommendations on filters
The system includes two separate channels (Air and O2) to provide dynamic
mixture control of the delivered O2 percentage.
The air supply can include an optional compressor unit, shown below, for
applications where pipeline air is not available or to provide a continued air
supply if the pipeline supply drops below 225-265 kPa (32.6-38.4 psi).

2.1.1 Primary gas inlet
Compressed gas enters the ventilator through an inlet fitting (2) that is
particular to the institution’s supply system. The gas is filtered through a 2micron particulate filter (3) and then a 0.5-micron coalescing particulate filter
(3a) as it enters the ventilator’s “pneumatic engine” manifold. The Air Pipeline
Inlet filter assembly (3a) is standard on all configurations. The O2 Pipeline Inlet
Filter assembly does not come standard, but is an orderable option. The 0.5-
2-2
2065496-001 Rev G (2024 12)
2 Theory of Operation
micron filter protects the ventilator from pipeline particle and liquid aerosol
contamination.
A high-pressure transducer (4) having a dynamic range of 0 to 8.3 bar (0 to 120
psi) is tapped at the outlet of the filter. This transducer monitors the adequacy
of the supply pressure. Failures of supply gas, coupling hoses or an occluded
filter are identified by the supply pressure transducer.

Next in the downstream path of flow is a check valve (5). The check valve
prevents backflow from the ventilator that would possibly contaminate the
supply pressure lines. For example, if the O2 supply were to be lost, the check
valve in the O2 channel will prevent Air from moving back into the O2 supply
lines.
Downstream from the check valve is a 172 kPa (25 psi) pressure regulator (6).
(The regulator is a non-relieving type that does not bleed gas into the
ventilator’s enclosure.) The regulator ensures a constant pressure supply to the
flow valve (8). The regulated supply is flow rate dependent, which is
compensated for in the flow valve’s on-site calibration.

Between the regulator and the flow valves is the inspiratory flow sensor (7). The
sensor is a thermal mass-flow type that injects heat into the flow stream and
monitors the associated temperature rise at a downstream location. The
temperature change is dependent on the mass flow of the flow stream and the
specific heat of the gas moving through the sensor. Because the composition of
gas in the sensor is known, a conversion of mass-flow rate to volumetric flow at
ambient conditions can be made using the ambient density of the gas. The
sensor uses a laminar (two channel) flow element to split a portion of the flow
through the sensor past the heat injection and temperature sensing elements.
The sensor is pre-calibrated and includes an electronic PCB that produces
direct digital output of mass flow through an RS-232 interface.
Individual flow sensors measure the volume of gas dispensed from the O2 and
Air channels during inspiration and expiration. The relative proportion of gas
dispensed from each channel is continuously adjusted to precisely control the
percentage of O2 delivered to the patient.
Downstream of the flow sensor is a flow valve (8) that meters flows from
approximately 0.05 l/min (leakage level) to a full flow value of 160 l/min. The
valve is a normally-closed proportional solenoid that is powered by a current
feedback loop. During calibration, the sensor is checked against the output of
the O2 and Air flow sensors to ensure proper operation. Data comes from the
Total Flow Sensor and is verified again by the Air or O2 Flow Sensors. Using
data from the inspiratory flow sensor, a precise volumetric flow versus input
current profile is developed that includes both the valve and regulator
characteristics.
A Bleed Resistor (9) is located in parallel with the O2 Flow Control Valve to
prevent pressure build-up between the O2 regulator and the Flow Control
Valve. This Bleed Resistor has a 35 ml/min nominal flow.
Following the two individual flow valves is the Total Flow Sensor (10). This
sensor is the same type as the individual flow sensors and is used to measure
the combined inspiratory flow being dispensed from the system. Using a known
2-4
2065496-001 Rev G (2024 12)
2 Theory of Operation
flow valve output along with atmospheric pressure and gas temperature
information, mass-flow data from the sensor is converted to delivered
volumetric flow towards the patient. During calibration, the sensor is checked
against the output of the O2 and Air flow sensors to ensure proper operation.

Following the Total Flow Sensor are the free-breathing check valve (11) and the
inspiratory effort valve (12).
During normal operation, the inspiratory effort valve is open, allowing the
freebreathing check valve to admit flow if the patient draws a significant amount
of inspiratory pressure, causing the airway pressure to become more negative
than -0.5 cm H2O. The free-breathing check valve allows the patient to
spontaneously breathe in case of a ventilation delivery failure.
On occasion, to assess the patient’s tolerance to be weaned from the ventilator,
clinicians can determine the amplitude of inspiratory effort that the patient can
create. During this “procedure”, the inspiratory effort valve is closed, effectively
locking out the free breathing valve from the patient circuit.

CARESCAPE R860
The O2 sensor uses the paramagnetic principle (oxygen molecules are
attracted in magnetic fields) to measure the oxygen concentration. The sensor
includes two nitrogen-filled glass spheres mounted on a suspension containing
a conductive coil that is located in a non-uniform magnetic field. When the
system is disturbed by an impulse of current, the suspension begins to
oscillate, inducing an EMF into the coil. The oscillation period of the induced
EMF is dependent on the partial pressure of oxygen surrounding the
suspension.
As sample gas fills the sensor, oxygen that is present in the sample is attracted
into the strongest part of the magnetic field. This congregation of O2 molecules
alters the natural oscillation frequency of the suspension. Calculations based
on the difference between the oscillation period for an oxygen sample and that
for nitrogen, and readings from the absolute pressure transducer, determine the
measured O2 percentage.
As a safety measure, a relief valve (14), located downstream from the O2
sensor, can be energized to vent the full flow rate of the inspiratory delivery side
of the system. If an overpressure condition is detected, the valve can be
opened by either of the ventilator’s two control processors. To provide
redundant safety, independent of the electronic circuits, the valve begins to
mechanically relieve pressure at a nominal 115 cm H2O.

The inspiratory airway pressure transducer (15), along with its associated
zeroing valve, is located just prior to the inspiratory outlet port. This transducer
has a range of –20 to 120 cm H2O and serves as one of three airway pressure
measuring devices in the ventilator.
2.1.2 Expiratory circuit
At the expiratory side of the ventilator, a solenoid powered exhalation valve (16)
controls exhaust from the breathing circuit. The valve contains an elastomer
diaphragm that is held against a rigid seat by a solenoid (voice coil) driven
piston. The valve achieves a balance between the pressure generated within its
21-mm diameter seat area and the force applied by the piston, releasing
exhalation flow as necessary to maintain balance. The proportional solenoid
controls the exhalation sealing pressure within a range of 0 to 100 cm H2O.
Software control provides continuous oscillatory movement (dithering) of the
exhalation valve to minimize static friction effects.

Immediately upstream of the exhalation valve is a tap for the expiratory
pressure transducer (17) and its associated zeroing valve. The expiratory
pressure tap is continuously purged with 35 ml/min of air to ensure that exhaled
condensate does not occlude the tap. The air flow is established from the
regulated Air supply using a fixed orifice (pneumatic resistor) (18).
Downstream of the exhalation valve is the expiratory flow transducer (19). In
principle, the transducer is similar to a hot-wire anemometer. A wire having a
large “temperature to electrical resistance” relationship is placed in the
flowstream. The wire is kept at a constant temperature using a Wheatstone
bridge circuit. The current necessary to maintain the resistance of the sensor
portion of the bridge is a function of the flow through the sensor.
At the output of the flow sensor is a flapper type check valve (20) that prevents
gas from being drawn in through the expiratory valve and minimizes patient
rebreathing in the event of a ventilator failure.
Located downstream on the patient wye is an optional Neonatal Flow Sensor
(28). The sensing elements for the Neonatal Flow Sensor Subsystem consist of
two hot wires each with its own drive circuitry and Wheatstone bridge. The hot
wires reside off-board in a flow tube situated at the patient wye and electrically
act as variable resistors in each of the bridges. The sensors hold a constant
temperature at all times as they contain a linear resistance change with
temperature. The Neonatal Flow sensor is connected to the Ventilator
Monitoring Board (VMB) through the Motherboard via Port 1 and a 2+ meter
long shielded cable, detachable at both ends.
The other Wheatstone bridge resistors and all associated drive circuitry reside
on the VMB. As gas (Air and Oxygen) flows, current through the hot wire
elements increases. These currents are converted to a voltage, amplified, offset
with a voltage reference and converted to a digital value by the 12-bit ADC.
Because of the bidirectional nature of gas flow at the patient wye, a post that is
situated between the elements serves to shadow the downstream element and
reduce the downstream signal. By comparison of the individual signal levels of
the two hot wire elements, flow direction can be ascertained.
2.1.3 Associated circuits
Associated with the inspiratory and expiratory pressure transducers are two
“zeroing” solenoid valves (21) and (22). These valves are used to disconnect
2065496-001 Rev G (2024 12)

the pressure transducers from circuit pressure and vent them to atmosphere

(every 12 hours) under the control of the Vent Engine software.

A third (auxiliary) pressure channel (23) is used to measure additional patient
“airway” pressures at the discretion of the clinician. This port could be used to
measure circuit pressure directly at the airway, laryngeal cuff pressures or
pressures lower in the airway tract. The transducer circuit includes a valve (24)
to provide a 35 ml/min purge flow as required by the particular clinical
application. For example, in measuring airway pressure at the endotracheal
tube the purge would most likely be turned on, but for measuring laryngeal cuff
pressures (closed system) the purge would be turned off. The purge flow is
established from the regulated Air supply using a fixed orifice (pneumatic
resistor) (25). The relief valve (26) limits pressure in the auxiliary channel to
less than 315 cm H2O.
2.1.4 Electronic micropump nebulizer
The Aerogen® Professional Nebulizer System (Aerogen Pro and Aerogen Solo
- disposable) by Aerogen, Inc. (27) is integrated into the ventilator. This
nebulizer is electrically connected to the ventilator and uses proprietary
technology to produce a fine-droplet, low-velocity aerosolized drug delivered
into the breathing circuit.
The Aeroneb Pro and Aeroneb Solo (disposable) is designed to operate in-line
with standard ventilator circuits and mechanical ventilators. It operates without
changing the patient ventilator parameters.

The display unit is physically separate from the ventilator chassis (connected
through a single cable running through the display arm). The display unit
contains four circuit boards: COM Express Module, carrier board, touch screen
controller, and alarm light. The COM Express Module contains the CPU and
RAM. The carrier board is the main circuit board and provides connections
between all subsystems within the DU. The touch screen controller manages
the touch screen and communicates to the system with a serial connection. The
alarm light provides a redundant visual alarm indicator.
The display unit communicates with the remainder of the system via the
Motherboard using five digital channels. Settings and alarm annunciation
information are directly relayed to the VMB and VCB from the display unit. The
display is a 38 cm active matrix LCD with 8 bits per color and a LED
background.
In the event of a display unit communications failure, the system will continue to
ventilate at the current settings.

Port 4 may be used to output alarm signals to a nurse call system. The
ventilator will signal an alarm with a normally open or normally closed signal.
The nurse call will be triggered by all medium and high priority alarms. When
alarm audio is paused, the nurse call signal will be off.
Note The delay time from the onset of an alarm condition to the alarm signal leaving
the nurse call port is up to two seconds. The facility is responsible for any
additional delays introduced by equipment connected to the nurse call port.

2.4.1 Ventilator Control Board
The ventilator control board (VCB) is a Motorola Coldfire V4 CPU powered
assembly that collects information from all ventilator system sensors (some
indirectly from the VMB), and controls all actuators necessary to affect
ventilation delivery.
The VCB computes and supplies all ventilation sensor monitoring data for
display on the display unit. If there are alarms to be generated based on this
monitoring data, the VCB notifies the display unit to post the appropriate alarm
message and audio sequence. The VCB observes the display unit’s response
to ensure that the alarm is adequately presented.
To control ventilation, the VCB accepts ventilation parameters from the display
unit. Measured data (waveform and numeric) is also sent to the display unit
from the VCB. This data flow occurs on the 38.4 Kbaud, RS-422
communications link (VCB - display unit Data I/O).
The VCB also communicates directly with the VMB every 2 ms, receiving
expiratory flow, expiratory pressure and O2 sensor data on the 921.6 Kbaud,
RS-422 interface (VMB Sensor Data I/O). Barometric pressure data is also
received from the VMB, but at a lower data rate.
The following sensor information is acquired directly by the VCB:
•
•
•
•
•
•
Air Flow/Temp sensor through the 12C interface at 250 Hz
O2 Flow/Temp sensor through the 12C interface at 250 Hz
Total Flow/Temp sensor through the 12C interface at 250 Hz
Inspiratory Pressure sensor via a differential analog signal – 12 bits at
1000 Hz
Auxiliary Pressure sensor via a differential analog signal – 12 bits at 1000
Hz
Proximal flow sensor via differential analog signal - 12 bits at 500 Hz
The VCB contains actuator drive circuits for the following:
•
•
•
•
Air and O2 Flow Valves
Exhalation Valve
Inspiratory Pressure Sensor zeroing valve
Auxiliary Pressure Sensor purge flow valve
The Flow Valve and Exhalation valve actuators are driven using current drive
circuits and feedback controlled using current sense resistors. The VCB
contains digital control signals for activating the inspiratory effort and safety
relief valves (through the VMB) and the Piezo-Electric Nebulizer.
The VCB receives 12.5 Vdc from the PMB, which it regulates down to various
voltages for use by the board’s digital circuits and analog drivers. These voltage
levels are self-tested on the VCB. An additional power line is separately
connected to an auxiliary buzzer on the VCB that provides a backup audio
alarm source. The buzzer is normally on and must be kept silent by both the
VCB and through a dedicated digital line coming from the VMB. A reset or
2-14
2065496-001 Rev G (2024 12)
2 Theory of Operation
failure of either the VCB or VMB is regarded as a system fault and the buzzer is
activated.
The VCB includes 1 MB of SRAM and 8 MB of Flash memory. The CPU is
connected to a digital watchdog circuit to monitor continuous and properly
sequenced execution of software code.
As the core processor unit for the ventilator, the VCB includes two external
serial I/O channels: one 115.2 Kbaud RS-422 channel (Expansion Port I/O #1
to External Connector 3) and one 115.2.2 Kbaud RS-422 channel (Expansion
Port I/O #2 to External Connector 2).

2.4.2 Ventilator Monitoring Board
The Ventilator Monitoring Board (VMB) is based on an Atmel Atmega 128 CPU.
The VMB performs as an independent monitoring system that provides
computational and oversight redundancy to the display unit and VCB (see the
diagram in "2.4.1 Ventilator Control Board").
The VMB independently acquires sensor data relating to the ventilator’s three
safety parameters:

Figure 2-6 • Ventilator Monitoring Board
The VMB controls a safety valve actuator that enables it to unilaterally relieve
pressure in the breathing circuit. Independent control from either the VMB and
VCB can signal the barotrauma hazard within a 50 ms reaction time. The
hazards associated with O2 concentration (improper mixture) and low exhaled
minute volume (hypoventilation) have much slower reaction times (minutes)
and are controlled under fault conditions by the VMB’s ability to unilaterally
activate the backup buzzer.
The VMB receives 12.5 Vdc from the PMB, which it regulates down to various
voltages for use by the board’s digital circuits and analog drivers. These voltage
levels are self-tested on the VMB.
2-16
2065496-001 Rev G (2024 12)
2 Theory of Operation
The VMB communicates directly to the display unit via the bi-directional 38.4
Kbaud RS-422 channel (VMB - display unit Data I/O). A separate 921.6 Kb
RS-422 link (VMB Sensor Data I/O) is used to transmit the VMB’s sensor data
to the VCB.
Neonatal Option
For Neonatal patients, the VMB provides circuitry designed to interface with the
VCB and VMB and a remote bidirectional gas flow sensor. The analog sensor
signals are routed from outside of the ventilator housing to the VMB via an
electrical harness to the back of the machine and are filtered on the
Motherboard before entering the VMB through the Motherboard internal
connector. This circuitry is provided 12.5V power via the Motherboard and
regulates this down to 5V and 3.3V, independent of other VMB circuitry.
2.4.3 Power Management Board
The power management board (PMB) is based on an Atmel Atmega 128 CPU.
The PMB performs power selection between power sources in the following
order:
•
•
AC power mains
Internal battery
The PMB regulates the 24 Vdc power supply output down to raw 16 V and 12.5
V power rails that are used throughout the system (all boards locally regulate
from these power rails).
The PMB controls the charging operation of the internal battery, selecting
trickle, bulk, or float charge status.
The PMB communicates with the display unit through the 38.4 Kbaud, RS-232
link (PMB Data I/O). It sends status commands to the display unit concerning
the charge status of the internal 24 V battery.
The PMB uses this link as a communication interlock to manage the unit
shutdown sequence. Once a signal is received by the PMB from the
mechanical On/Standby switch, the PMB prompts the display unit for a
confirmation signal that shutdown is appropriate (unit is not in a ventilation
therapy state). Once the display unit relays this confirmation to the PMB, the
power-off sequence is initiated.
The PMB supports the operation of the ventilator chassis fan and the fan on the
PMB heatsink.
2.4.4 Other electronic items
The ventilator employs a separate AC to DC switching power supply for
providing a nominal 24v voltage level to the PMB. The power supply is capable
of regulating 150 W of power output. A power entry module contains fuses and
filters for Mains AC input cables. Finally, two internal 12v batteries are
2065496-001 Rev G (2024 12)
2-17

connected in series to provide an internal backup 24v power source for the
system.

current limiting for external peripheral connections to ensure that the primary
ventilation and monitoring functions are not compromised by excessive power
draw. In addition, 10VA energy limit circuitry is provided for power connections
within 20 cm of O2 exhaust outlets, in order to mitigate the risk of an oxygen
enriched fire. The board features six external connectors that exit through the
rear interface, see "2.3.3 Communication port connections".

4.1 System configuration and defaults
This section describes how to configure facility defaults, how to manage
passwords, and how to use service tools such as calibrations, software
upgrades, and view logs.
The section "8 Service Diagnostics and Software Download" describes two
other service applications, the Service Application and the PC Service
Application.
The "8.1 Service Application" runs from a USB media stick and is used to
download system software and run service level diagnostics.
The "8.7 PC Service Application" runs from a USB media stick on a Windows
based computer and is used to perform service level tests and troubleshooting.
4.1.1 Configure passwords (Install or reset)
The Password change required prompt shows at startup during installation and
after a password reset to factory defaults. The prompt shows at startup until the
Service password and Configuration password are both changed from the
factory default values.

5.1 Calibration (super-user and service)
WARNING After adjustments and calibration are completed, always perform
the Checkout procedure. See "3 Checkout Procedure".
The ventilator includes integrated software that allows a qualified user to
calibrate the O2 flow valve, the Air flow valves, Exhalation valve, airway
module, and touchscreen.
At a minimum, these calibrations should be completed every six months,
whenever performance is questioned, or when associated components are
serviced or replaced. These calibrations can be performed more frequently, as
needed, for optimal performance.
Note The valve calibrations in "5.1.1 Calibration procedures" can be performed
without performing the service level tests and calibrations in "5.2 Service level
tests and calibration". However, if the service level test and calibrations are
performed, the valve calibrations should be performed again after the service
level tests are completed and passed.
Note To file a quality report or request technical assistance regarding a calibration
failure, create and include a Calibration log while using the PC Service
Application. For details, see "8.7.4 Log calibration results to file".
Run the calibration while the PC Service Application is running and select Log

The measured flow values are shown in real-time in the VT insp and VTexp
fields in the Airway Module Spirometry Data menu. The acceptance criteria
is:
•
•
If the VT insp and VTexp values differ less than ±30 ml of 500 ml, flow
calibration is not needed.
If the VTinsp and VTexp values differ more than ±30 ml of 500 ml,
perform flow calibration according to the Compact Airway Technical
Reference manual, M1153491 Section 4.3.3, Flow Calibration.
Patient spirometry does not require regular service calibration during planned
maintenance, or after the PVX (pressure transducer) unit has been replaced.
The PVX measuring unit is calibrated at the factory and due to the unit’s design,
spirometry calibration is not regularly needed in the field. The calibration data is
saved into the board’s EEPROM.
In case calibration is needed, it is recommended to perform the calibration both
with adult values using the D-lite and with pediatric values using the Pedi-lite.

6.8.1 Battery information
The ventilator can operate on battery power.
•
•
A minimum of 30 minutes when the batteries are maintained in accordance
to the battery performance procedure.
Up to 85 minutes when the batteries are new and fully charged.
WARNING Do a battery test every 6 to 12 months to make sure battery
capacity is at least 30 minutes. Replace the batteries when
necessary.
Important
The ventilator is not intended for use during the transport of patients between
facilities or emergency transport. The batteries are intended for use as backup
power in case of a main power failure. Transition to battery is done
automatically by the system.
The ventilator uses two internal 12 Vdc sealed lead-acid batteries to provide
backup power when main power is not available. The battery is typically in a
float charge state as long as the system is connected to a primary electrical
source.

•
Actual operation time on battery power depends on ventilator settings,
battery age, and level of battery charge. The battery capacity specifications
are approximate.
To maximize battery life, maintain a full charge and minimize the number of
discharges.

The “No battery” icon shows when there is a battery error or battery power is
not available.
The Battery in use alarm becomes active when the ventilator changes from
main power to battery power. If the ventilator continues to operate on battery
power, it alarms to signal that approximately 20, 10, 5, and 1 minute of battery
power is available.
6.8.3 Storing the ventilator
WARNING Keep the ventilator connected to the main power even when it is
not in use. It is recommended that the ventilator remain connected
to the main power to prevent battery discharge and degradation.
Use only Datex-Ohmeda recommended batteries.
The green LED on the lower left side of the display unit is on when the
ventilator is connected to the main power source.

7.1 Troubleshooting checkout failures
If the System Check ( "3.2 System checkout overview") results in failures, use
the following tables to troubleshoot a specific failure. Use the PC Service
Application ("8.7 PC Service Application") while running all tests. Additional
information regarding Checkout failures is available in the Event Log.
To file a quality report or request technical assistance regarding a checkout
failure, create and include a Checkout log using the PC Service Application, as
well as, the Event Log.
Important If multiple failures occur during Super User Calibrations, System Check, or
Service Procedures, particularly those tests associated with air supply, it could
be an indication of water or hydrocarbon contamination. If you suspect
contamination of this type, inspect the pipeline inlet filters for signs of
contamination. Contamination of this type would require the replacement of all
contaminated components or the Vent Engine Sub-assembly, based on the
extent of the contamination.

7.2.2 Expiratory pressure circuit test
If the low pressure vent engine leak test ("5.2.5 Vent engine leak test (low
pressure)") fails step 6, the following steps will verify flow and integrity of the
Expiratory pressure circuit. Flow in this circuit is restricted, therefore, failure to
build pressure during the low pressure leak test is not an indication of an
excessive circuit leak or purge flow issue. However, passing the low pressure
leak test does indicate circuit integrity and therefore the following tests are only
necessary, if step 6 fails.
1.
2.
3.
Ensure the air shut-off valve is open and supply is available.
Set the exhalation valve raw counts to 60,000 and activate by checking the
box.
While monitoring the expiratory pressure, plug the Expiratory Valve inlet.
Pressure should rise to 70 cmH2O within 7 seconds. If it does, the purge
flow is sufficient and the leak rate is not excessive.
•
•
4.
If not, check the pressure port seal in the Exhalation Valve Assembly,
and/or replace the Exhalation Valve Assembly and repeat the test.
If the test still fails, continue.
Remove the vent engine per "9.4.1 Removing the chassis from the
housing".
WARNING Before removing restrictors, shut off the supply valves and open
the flow valves to bleed system pressure build-up.

7.3 Troubleshooting Vent Engine Components
If you encounter multiple failures during the Super User Calibrations, System
Check, or during the Service Procedures, especially tests associated with air
supply, it could be an indication of water or hydrocarbon contamination. If you
suspect contamination of this type, inspect the pipeline inlet filters for signs of
contamination. Contamination of this type would require the replacement of all
contaminated components or the Vent Engine Sub-assembly, based on the
extent of the contamination.

2.
Attach a manual shut off valve to the gas supply for the Regulator Under
Test (RUT).
Enter the Super User mode.
Calibrate the RUT per "5.2.4 Regulator output pressure test".
Verify the pressure is stable and does not increase above 179 kPa (26 psi)
when the Flow Valve is off.
Turn off the shut off valve.
Set the Flow Valve DAC to 60,000 for the gas being tested to bleed the
trapped pressure.
Re-set the Flow Valve DAC to 0.
Slowly, open the shut off valve until pressure begins to rise.
If pressure continues to rise above 179 kPa (26 psi), the regulator should
be replaced.

WARNING To prevent fires:
•
•
Use lubricants approved for O2 environments, such as Krytox. Other lubricants may burn or explode
in high O2 concentrations.
All covers used on the system must be made from antistatic materials. Static electricity can cause
fires in high O2 concentrations.
WARNING Obey infection control and safety procedures. Used equipment
may contain blood and body fluids.
WARNING A movable part or a removable component may present a pinch or
a crush hazard. Use care when moving or replacing system parts
and components.
WARNING Some internal parts have sharp edges and can cause cuts or
abrasions. Use care when servicing internal components.
WARNING When servicing the ventilator, extreme care must be taken to
avoid introducing foreign debris into the pneumatic flow passages
of the ventilator. This includes dust and contaminants on the vent
engine and particularly metal chips generated by screw threads.
Before removing components on the vent engine, secure a clean
work area and thoroughly clean the vent engine to remove any
contaminants. Failure to do so may result in damage to the
internal components.
WARNING After repairs are completed, always perform the System Check
(Section 3) of this manual.

9.2 Circuit board replacement precautions
The ventilator stores the system serial number and installed optional features, if
any, in the following locations:
•
•
•
Display Unit CPU board
Vent Control board (VCB)
Power Monitor board (PMB)
Each time the system is powered up, the software checks to ensure that the
information stored in these locations is the same.
If, on power up, only two of the three boards have matching information (such
as would be if one of these boards is replaced), the software loads the
information from the two matching boards to the third board. This scheme
allows for replacement of these boards while retaining machine specific
parameters.
Note No checking or replication occurs when the Service Application is loaded. The
unit must be powered up with system software.
CAUTION Do not replace more than one of these boards at a time without
first powering up the unit. Wait until the initial checkout menu
appears to ensure that the machine specific information has been
replicated.
9.2.1 Software download
After replacing any of the following boards, download the current software for
the newly installed subsystem. See "8.2 Software Download".

9.4 Access to chassis components
Most of the system components are mounted to a two-tier chassis (A) that
slides out of the main housing (B) for access to the internal components.
The pneumatic and related Vent Engine (C) components are mounted on a
manifold that occupies the lower tier of the chassis. To access the pneumatic
components, the entire manifold assembly can be removed from the chassis.
The electrical and related circuit board components occupy the upper tier.
Electrical components on the Vent Engine connect to the Ventilator Control
Board (VCB) and the Ventilator Monitor Board (VMB) through a single, twoconnector harness.
To diagnose the operation of the ventilator while still disassembled, the
components (Vent Engine, circuit boards, display unit) can be arranged and
reconnected with existing harnesses. A separate Display Unit Cable can be
used as a service tool to make the connection between the Chassis and the
Display Unit (D) less restrictive. See "10.1.3 Special tools".

Always perform Vent Engine Debris Cleanout after replacing components, see
"5.2.3 Vent engine debris clean-out".
Lubricate o-rings using a small amount, only enough to wet the surface of the
o-ring, of Krytox prior to installation
Important If you encounter multiple failures during the Super User Calibrations, System
Check, or during the Service Procedures, especially tests associated with air
supply, it could be an indication of water or hydrocarbon contamination. If you
suspect contamination of this type, inspect the pipe inlet filters for signs of
contamination. Contamination of this type would require the replacement of all
contaminated components or the Vent Engine Sub-assembly, based on the
extent of the contamination.
Cleaning and repairing the Vent Engine
1.
Use compressed air to blow any loose particulates and dust from the
manifold and components prior to loosening fasteners. Use caution around
small parts and elastomers such as o-rings and diaphragms.
2. Obtain alcohol prep pads or similar damp cleaning wipes before removing
components. Do not use materials that will lose fibers or leave a residue on
components.
3. Completely remove all fasteners and place in a temporary container before
moving the component.
4. Carefully lift the component straight up and away from the manifold. Check
to make sure all necessary o-rings and gaskets are present. Store
components in a temporary container and not on the workspace tabletop.
5. If the component is going to be re-installed, place it on its side or back on a
clean surface to protect the mating surface.
6. Using an alcohol prep pad, damp wipe clean the manifold surface by
starting at the opening and wiping away from it. This will reduce the risk of
loose material dropping into the manifold.
7. Carefully inspect the opening in the manifold. If there is any visual sign of
contamination or discoloration, the manifold and any upstream
components must be replaced.
8. If the component removed is to be reinstalled, clean it in a similar manner
by wiping from any gas stream access points toward the outside edge.
9. Carefully inspect the component and seal. If there is any sign of
contamination, knicks, small tears, or discoloration, the component and or
seal must be replaced.
10. Carefully set the component back on the manifold directly over and aligned
with the attachments. Avoid sliding the component after it is in contact with
the manifold.
11. Reinstall the fasteners and torque them to the required specification as
listed.
Note Perform "5.2.3 Vent engine debris clean-out" after replacement of vent engine
components.
Note When replacing components, do not over tighten the mounting hardware. Use
the following torque spec table to properly mount the component.

CAUTION Use care when applying torque to the front casters. Avoid contact
with the adapter and cart base while tightening. There is a raised
edge (B) on the cart base and a false torque could occur if contact
is made.
--
Important If you are unable to use the method shown (adapter at 90 degrees) in step 6, it
is possible to torque the caster with the wrench adapter in line with the torque
wrench as shown below. If using this method, it is necessary to re-calculate the
torque that will be set on the wrench to accommodate the additional length
added by the adapter. Use the equation and image shown to determine the
torque value that you should set the wrench

Ta = Torque applied at the adapter. This is the value required for your caster application
in Newton-meters.
A = Length of adapter for your application in meters.
L = Length from square drive to hand position (should be center of handle ) in meters.
Tw = Torque valve that the wrench is set to in Newton-meters.
8.
Once the caster is set to the proper torque and the caster collar is
tightened, mark both the caster collar and the cart base using a permanent
marker (preferably black).
•
•
•
Rotate the plastic collar on the caster clockwise (tighten). This takes
up clearance between the plastic collar and the steel stem for
consistent marking and inspecting.
To aid in future inspection, make a small mark on the cart base (A) and
caster collar (B). These marks will be used in the future to provide a
visual aid to determine if the caster has loosened.
If the base was previously marked, then remark the replacement
caster collar using a permanent marker to align with the existing mark
on the cart base (A).

9. Before lowering the machine, make sure the caster turns freely.
10. Carefully lower the machine to the floor.
11. Reassemble the machine:
•
•
•
Install the ventilator on the cart.
If the compressor was removed, reinstall the compressor - refer to the
appropriate Technical Reference Manual.
Tighten all power cord retainers that were loosened to 0.45 Nm.
12. Perform an Electrical Safety Test after installing the ventilator and/or
compressor to the cart.
13. Perform a System Check "3.2 System checkout overview".

9.10.1 Production Marking
Grooves are now located on all four caster collars and corresponding locations
on the cart base assembly. These grooves are intended to be used to provide a
visual aid to determine if the caster(s) have loosened.
If you are replacing a caster on a machine that has a production groove, use a
permanent marker (preferably black) to mark the caster collar to align with the
groove in the cart base.

9.11.1 Mounting and connecting the airway module bay
The airway module bay may be mounted on either side of the ventilator.
WARNING Do not place the airway module in the lower slot when the airway
module is on the right side of the system. Exhaust from the gas
exhaust port will adversely affect the accuracy of the airway
module CO2 and O2 measurements.
•
Install only one airway module into the airway module bay.
The system does not support the use of multiple airway
modules.
•
Only install singe width airway modules (E-miniC and
CARESCAPE respiratory modules) in the upper right slot of
the airway module bay. The upper left slot of the module bay
does not support communication between the module and the
system.
CAUTION The airway module bay port must only be used for connecting the
module bay to the ventilator.

A.2 Medical-Grade Air Auxiliary Filter Recommendations
The ventilator was designed to be operated using Medical-Grade Air. The
generally accepted standards for medical air are ISO 8573-1:2002 (E)
specifications quality class 1.2.1, Breathing Air. The key elements that relate to
equipment reliability are liquid hydrocarbons, moisture, and particulates. In
general the standards for medical air from an air compressor system calls for
no particulates larger then 1.0 micron, a maximum pressure dew point of 39°F
(4°C) at 50 psi, and a maximum oil content of 0.01 ppm.
The ventilator has internal inlet filters, and optional inlet filters are available if
the integrity of the customer’s ventilator pipeline is questionable. The intent of
the internal filter is to block any large particles that may be introduced when the
ventilator is not connected to a wall source or during the connection process, it
does not filter particulates finer than 5 micron, oil or moisture. The optional inlet
filter is provided to give a visual indication of contaminate problems. It has a
clear bowl so that the filter material is visible to the user. If there is any
indication of contamination from particulates or moisture, the ventilator should
be removed from the source and the source must be cleaned. This inlet filter
will not protect the ventilator from damage if a continuous source of particulate
or moisture is present in the supply lines.
Damage to the ventilator due to medical gas contamination is not a warranted
condition. The ventilator should only be operated using medical-grade gas. GE
Healthcare LSS Research and Development Engineering conducted tests to
determine if a filter, or a combination of filters would effectively remove
contamination from an unfiltered source.
Listed below is the filter combination that provides the best results when used
under ventilation conditions. None of the filters tested, including the filters listed
were 100% effective. GE Healthcare does not warranty these filters nor make
any specific claims of their efficacy or reliability. Use of these filters does not
change the ventilator product warranty. GE Healthcare is not responsible for the
maintenance or support of these filters.
•
•
Wilkerson Particulate filter F28 Type A with automatic drain
Wilkerson Coalescing filter M18 Type B with automatic drain
The coalescing filter can capture particles down to 0.01 micron, so the
particulate filter must be installed up stream of the coalescing filter, otherwise
premature failure can occur. The filters must be properly maintained as
recommended by the filter manufacturer. Only genuine replacement parts from
the filter manufacturer must be used. GE Healthcare will not supply these filters
or mounting hardware. All components must be sourced and assembled locally.
The filters must be mounted to the cart or wall and a hose connection between
these filters and the ventilator inlet is required to minimize stress on the inlet
manifold. Adding filters to the pipeline source can cause a pressure drop to the
ventilator. This pressure drop will increase as the filters degrade, replace filters
frequently.
Other manufacturers filters may be substituted if they meet or exceed all of the
performance specifications of these filters.
