SECTION 3. PRINCIPLES OF OPERATION
3.1 INTRODUCTION
This section provides overall theory of operation and functional description of the
DINAMAP PRO 1000 (hereinafter referred to as PRO monitor). The PRO monitor
has Blood Pressure (BP), Pulse, Temperature, SPO2, and ECG monitoring
capability. The printer module is optional.
3.2 OVERALL PRINCIPLES OF OPERATION
The following paragraphs provide a general system interface relationship. The
general block diagram is located in Figure 3-1.
The PRO monitor is a portable unit that receives input power from an external AC
source, external DC source, or internal rechargeable battery.
When the ON/OFF button is pressed, the Main Board is brought out of a sleep
mode and turns on the power regulators. The power regulators provide conditioned
power from one of the input power sources: AC Mains, External DC, or the internal
battery. The regulated power is routed to the Printed Wiring Assemblies (PWAs) via
the cable harnesses. Once the PRO monitor is energized, a self-test is performed.
The self-test automatically tests the main functions of the PRO monitor. Failure of
the self-test will set the PRO monitor into a fail-safe mode with an audio alarm.
Under normal operating condition, the PRO monitor is ready to monitor the patient
vital signs using five external attachments: two temperature probes (rectal and
oral), SPO2 sensor, ECG leads, and cuff. Interface with a central station or other
device is accomplished through the 9-pin host communication port or 15-pin
wireless communication port on the back of the PRO monitor.
3.2.1 Nellcor SPO2
When the SPO2 sensor is attached to the SPO2 connector and patient, it senses
the heart rate and oxygen saturation. These analog signals are routed to the SPO2
PWA. The analog signals are analyzed on the SPO2 PWA. The results are digitized
and sent to the Main Board via opto couplers. The couplers provide for patient
isolation as well as serial data interface. The Main Board routes the data to the
appropriate displays and/or printer.
A reset signal to the SPO2 PWA is also provided for power up sequencing.
3.2.2 Cuff Blood Pressure (BP) and Pulse
When the cuff and hose are attached to the PRO monitor and Non-Invasive Blood
Pressure (NIBP) determination is initiated, the pump inflates the cuff. Pressure
transducers PT1 and PT2 monitor pressure information. The pneumatic manifold
3-3
has two valves, which are used to deflate the cuff. Valve control is through the Main
Board. Determinations are made for the systolic BP, diastolic BP, pulse rate, and
Mean Arterial Pressure (MAP). The results are displayed on the front panel Liquid
Crystal Display (LCD).
If an over-inflation condition occurs, it is detected by PT2, resulting in assertion of
OVERPRESSURE. The OVERPRESSURE signal is routed to the PVM to release
the air pressure. The Main Board also generates an alarm condition with the
speaker sounding and a message in the LCD.
3.2.3 Alaris Oral and Rectal Thermometry
The PRO monitor has two temperature channels, one each for oral and rectal
determinations. When a TEMPERATURE probe is attached to the temperature
connector and patient, TEMP input is routed to the Main Board. This input
represents the temperature to be measured. The Main Board converts the TEMP
signal to a digital signal. During the conversion, the Main Board determines the
patient temperature using a predictive or monitor mode algorithm depending on
user setup. The patient temperature is distributed as a digital signal to the LCD
display or printer.
The PRO monitor has a probe check feature to help prevent erroneous temperature
readings stemming from using the wrong probe for determinations (i.e. oral probe
for rectal determination and vice versa.)
3.2.4 ECG with Heart Rate and Respiration
The ECG parameter provides electrocardiographic waveform in a 3-electrode
configuration. The 3-electrode configuration derives waveforms for leads I, II, or III.
It includes a waveform cascade feature and can display one waveform as the
primary lead.
Breath rate is calculated by measuring the thoracic impedance between two
electrodes. As the patient breathes, the movement of the chest changes the
measured impedance to produce the respiration rate.
3.2.5 Host Communication Ports
There are two Host Comm Ports provided on the back panel of the PRO monitor.
The DB9 connector provides +5V(600mA Max), +12V(400mA Max), and two
channels of TTL compatible communications. The DB15 connector provides
+5V(600mA Max), +12V(250mA Max), Remote Alarm Signal, and a TLL/RS-232
selectable communication channel.
Note: When the DB15 port is enabled, channel 2 of the DB9 port is disabled.
The Host Comm Ports are used to interface the PRO monitor with other electronic
devices (a central nurse’s station or remote alarm device.) Signals can be sent to
the PRO monitor to initiate blood pressure determinations and other functions.
Patient data can also be retrieved through this port. The DB9 connector should be
used with Critikon Adapters ONLY. The host port signals on the DB15 connector
are NON-ISOLATED and should be connected to equipment conforming to IEC
3-4
601-1-1 ONLY. Where isolation of data communication is required, the Critikon
isolated level converter should be used. If external alarm control is required,
Critikon part number 487208 (Isolated Remote Alarm Cable Assembly should
ALWAYS be used. Please refer to the Information Sheet included with the isolated
remote alarm cable for operational details.
Note: When using remote alarm, the PRO monitor should be considered the
primary alarm source. The secondary alarm is used for secondary purposes only.

3.3.1 PSU PWA
The PSU supplies regulated DC power to PRO monitor. The PSU PWA is designed
to operate from the output of the AC MAINS PSU module (+24VDC), EXTERNAL
DC (+24VDC to +28VDC) source, or from an internal NiMH rechargeable battery
(+12VDC). The PSU will automatically select the power source based on the
following priority:
• Valid EXTERNAL DC input = +16VDC (If greater than or equal to output of
Mains Converter)
• Valid AC MAINS input
• Valid NiMH battery
The PSU PWA converts the selected power source into the following main voltages:
• VRAW1 (14.4VDC)
• VRAW2 (14.4VDC)
• VBAT
The +12V printer supply voltage is down converted from VRAW1 and maintained by
a boost regulator to +12V when VRAW1 falls under 12V. ANA+ is regulated to
+14.4VDC from VRAW2 by a MAX668 step up controller. AUX +12V is down
3-5
converted from ANA+ using an LM340 regulator. ANA- is down converted from
VRAW2 to –14.4VDC using a LM2594 step down regulator.
VBAT is the battery voltage protected by a 500mA auto-reset fuse. It is also used to
power the failsafe alarm circuits on the Main Board.
The PSU PWA contains firmware that reports the charge status of the battery to the
secondary processor on the main board. The secondary processor will charge the
battery at the fastest rate allowable while keeping the PRO monitor power
consumption under 60W.
The fan control circuitry is located on the PSU PWA and is powered by VRAW1.
The circuitry is thermally controlled and will start the fan when the thermistor (TH1)
reaches approximately 50°C.
The host communication port control circuitry selects whether channel 2 is routed to
the Comms connector (DB-9) or the wireless connector (DB-15). If channel 2 is
routed to the wireless connector, it can be configured for RS-232 or inverted TTL
signals. Channel 1 is only available on the Comms connector as inverted TTL.
3.3.2 Mains Converter Module
The Mains converter module is an AC Mains to DC converter. The module receives
AC power from the mains input connector. When AC INPUT is applied to the
module, the module AC/DC Converter changes the AC INPUT supply via rectifier
circuit to a high voltage DC. The DC power is then routed through a high frequency
switching converter and regulated to 24 VDC. This supply is connected to the PSU
PWA for further regulation. The PSU only selects this source when DC Output is
greater than +16VDC AND greater than the EXTERNAL DC input voltage.
3.3.3 Main Board
The Main Board is configured with Flash ROM, EEPROM, RAM, 16-bit ADC,
Primary Processor, Secondary Processor, SPO2 Module, and Temperature
Module. The Primary Processor operates from a 4.9152 MHz crystal stepped up to
49.152 MHz. The Primary Processor services and controls the RAM, Flash ROM,
EEPROM, the physiological interface modular devices and display backlighting.
The Secondary Processor monitors the power supply circuit, controls the poweron/off sequences, performs watchdog task on itself and the Primary Processor,
monitors signals within the NIBP module, and monitors board temperature. The
Secondary Processor monitors the power supply circuit and controls the battery
back up enable when no external sources are present and will shut down the unit
when the battery is exhausted. It will enable the battery charging circuit based on
the battery charge status, unit power consumption, and the availability of an
external power source.
The SPO2 processor monitors pulse oximetry signal and passes the processed
signals to the SPO2 interface chip. The interface chip takes the signals and derives
the oxygen saturation and heart rate data and converts them into serial data. The
serial data from the SPO2 interface chip are send across an isolation barrier
(optocouplers) and passed to the Primary Processor via a dual-channel UART.
3-6
The Temperature Module is a dual channel system. Two IVAC probes and the
calibration resistor chain are connected into a multiplexer that is controlled by a
single chip micro controller. The micro controller will then switch the output of the
multiplexer between the calibration chain and the two probes. The multiplexer
output is buffered, level shifted and amplified before being connected to a
MAX1241 12 bit serial DAC, which is read by the microcontroller. The
microcontroller will compute the resistance for each probe (and associated leads)
and transmit both resistance values to the Primary Processor in a 34-bit data
stream. A switch controls each probe; the Primary Processor will interpret the status
of the switches, and select the appropriate part of the data stream from the
temperature circuit.
The Random Access Memory (RAM) is comprised of a SRAM chip and two SDRAM
chips. The 512 Kbytes of battery-backed SRAM is provided to store trend data and
to provide space for working algorithms and is accessed on bits D[0:15] of the data
bus. The two 64 Mbit SDRAM chips are set up to form a 32 bit data bus on bits
D[31:0] that is used for running the program and working memory. This gives
16Mbytes of memory with an access time of less that 20ns. The program is loaded
(including the boot code) from the 16 bit FLASH Read Only Memory (ROM). The
Electronically Erasable Programmable Read Only Memory (EEPROM) is an 8 bit
chip that is used to store the calibration and other “setting” variables that have to be
maintained in the event of a complete power failure.
If a hardware or software error causes a malfunction, its watchdog will provide an
internal and external RESET(L) signal. The FAILSAFE controller will cause the
FAILSAFE(L) signal to go low. This signal passes to the Secondary Processor,
which will disable the Primary Processor’s power supplies, thus turning it off.
FAILSAFE(L) also passes to the PAL (NIBP control logic), which will dump the cuff
pressure. The system is left in a safe state but is remains on to enable the
Secondary Alarm to stay active. The Primary Processor monitors the activity of the
secondary via its handshaking communications. If the Secondary fails, the Primary
can assert the FAILSAFE line by overriding the FAILSAFE controller. The
Secondary Alarm is a hardwired alarm that will sound in the event of a FAILSAFE
condition. Pressing the OFF-key can immediately reset this alarm although it will
eventually time-out after about 10 minutes.
3.3.4 ECG PWA
The ECG PWA accepts signals from a 3-electrode cable for processing. The 3electrode cable provides a single lead configuration with Lead I, Lead II, or Lead III
available. The cables specified by Critikon are shielded and provide 1k-Ohm series
(safety) resistors internal to the cable that are part of the current limiting defibrillator
protection circuitry. Gas surge arrestors on the PWA provide lead-to lead
defibrillator protection. In addition, a passive R/C network located on this PWA
provides the first stage of high frequency filtering for EMC and ESU interference
rejection. Two leads are selected for ECG measurement by a multiplexer (LS0, LS1
signal controlled) and passed to a differential amplifier. A second multiplexor
selects the third electrode (the one not sent to the differential amplifier) and drives
3-7
the signal with an amplified and inverted version of the common mode voltage of
the two measuring electrodes. This feedback action cancels most of the common
mode signal applied to the differential amplifier. The output signal from the
differential amplifier is then routed to bandpass filter and pacemaker detection
circuit.
The ECG PWA uses the pacemaker detection circuit to prevent pacemaker signals
from interfering with heart rate measurements. The ECG signals are sent through a
bandpass filter designed to pass pacemaker pulses in preference to ECG signals.
The filter output is applied to a comparator that asserts an output signal when the
input signal exceeds its positive or negative threshold. This output signal is used by
the controller to blank the ECG signal channel and alert the host to the presence of
a pacemaker pulse. The filtered ECG signal is routed to the A/D converter for
transfer to the Main Board.
The respiration circuit uses the ECG electrodes to measure respiration rate. This is
achieved by applying an excitation current (61.5 kHz, well outside the bandwidth of
normal ECG signals) generated by a square wave switch onto two selected
electrodes. The measured voltage drop is filtered, the baseline component
removed, and amplified. The analog voltage representing the impedance (resp
value) is routed to A/D converter for transfer to the Main Board.
The ECG PWA provides isolated power to its circuitry using an isolation
transformer. A transformer driver drives the transformer primary at a frequency of
about 350 kHz. The voltage of the transformer secondary is full-wave rectified using
two Schottky barrier diodes. The isolated voltage is filtered by capacitors and
regulated by a +5V regulator. Isolated ground is obtained from the center tap of the
transformer. The data transferred from the A/D converter to the host is isolated
using optocouplers.
3.3.5 Keyboard PWA
The Keyboard PWA provides access to the basic functions of the PRO monitor. The
buttons that control each function are integrated with its status LED to form a touch
pad front panel. LEDs indicate the status of those functions by illuminating green
when active and yellow when inactive. The exception is the “SILENCE” button,
which is red when active. The function LEDs are driven by latches on the Main
Board. The battery LED is continuously yellow when the unit is running on battery
and flashes yellow when the battery is charging. The AC LED is green when an
external power source is present. The keyboard is connected to the Main Board via
a 36 way board-to-board connector.
3.3.6 Pneumatic Control
The pneumatic functional block includes the control signal decode logic, the valve
driver circuitry, the pump driver circuitry; pump current measurement circuit, and a
safety interlock circuit.
There are two transducers on board, PT1 and PT2. PT1 is used for main readings
while PT2 confirms readings and is used to derive overpressure signals. The
3-8
following signals are multiplexed into a 16-bit SAR A/D converter via an 8:1 channel
DG408:
• PT1A - the output of the measurement pressure sensor after
amplification and filtering by means of a passive 1KHz low pass antialias filter.
• PT1B - the output of the measurement pressure sensor after
amplification and filtering by means of a passive 20Hz low pass antialias filter.
• PT2 - the output of the confirmation/over-pressure sensor after
amplification.
• TH REF - the voltage that the amplified PT2 has to attain before the
safety circuit cuts in
• PT1 REF - the reference voltage that provides an offset voltage for the
PT1 amplifier
• PT2 REF - the reference voltage that provides an offset voltage for the
PT2 amplifier
• PUMPC - the pump current
• VBAT- 1/11 ratio of VBAT voltage
The 16-bit value out of the ADC is available on the data bus at D[15:0].
Control signals for the board are derived via four different sources: direct control
from outputs of the processor, controls signal derived from processor address write
commands (which are stored in an addressable latch), signals derived from the
watchdog timer, and signals generated by the overpressure functional block. The
four valve control signals and the pump control signal are derived from the write
address and stored in an addressable latch. Latch values are cleared by application
of system RESET generated by the processor. Each latch signal is individually
gated in a programmable logic device (16V8) with the fail safe input signal
(watchdog timer) and the overpressure latch output to ensure pressure is removed
from the patient cuff should either overpressure or processor failure condition occur.
A cross-coupled latch for overpressure is included in the programmable logic
device. It is set by the occurrence of an overpressure condition existing for a period
greater than 500 milliseconds. When this condition occurs, Filter_OVP-0 transitions
low setting the internal latch. The latch output state is indicated by the
Latched_OVP signal. The latch can only be cleared by the PNEURESET input.
3.3.7 LCD Assembly
The PRO monitor uses TFT (thin film transistor) active matrix color liquid display.
The 10.4” diagonal display contains 640 x 480 pixels and can display 262,144
colors simultaneously. The display is backlit by cold-cathode fluorescent lamps.
Note: the backlight power inverter is mounted separately from the other PCB’s.
The LCD is driven from the Primary Processor via buffers (HCT244) on a dedicated
LCD driver port:

4.3 PERIODIC MAINTENANCE
4.3.1 As Required
Perform the following maintenance procedures as required.
4.3.1.1 Integrity of Hoses and Cuffs
When the pneumatic integrity of any NIBP cuff and hose is in doubt, replace the
cuff and hose, and discard the questionable accessories.
4.3.1.2 Cleaning of Monitor
CAUTION: Do not clean Monitor with isopropyl alcohol or other
solvents.
Wipe the exterior of the Monitor with a cloth slightly dampened with mild
detergent or normal hospital bactericides. Use dishwashing detergents such as
IVORY and JOY (registered trademarks of Procter & Gamble Corp.), or
PALMOLIVE (registered trademark of Colgate-Palmolive Corp.)
Do not immerse unit.
4.3.1.3 Cleaning of Accessories
Clean the adult cuffs supplied for use with the monitor by hand washing in
warm, soapy water. However, take care to avoid entry of water into the cuff and
hoses at any time. If water enters the cuff, dry the cuff by passing air through it.
The neonatal cuffs are for single patient use - discard if they become soiled.
Clean cuffs and hoses with a cloth slightly dampened with mild detergent.
Do not immerse hoses.
Do not immerse cuffs without prior application of cuff hose caps.
Clean SpO2 sensor surface before and after each patient use. Clean SpO2
sensor with a cloth slightly dampened with a mild detergent. Wipe SpO2 sensor
to ensure all detergent residue has been removed.
Follow manufacturer's instructions for cleaning ECG lead wires and cable.
Compatible cleaning and disinfecting solutions are:
4-7
Dishwashing detergents such as IVORY and JOY (registered trademarks of
Procter & Gamble Corp.), or PALMOLIVE (registered trademark of ColgatePalmolive Corp.)
Chlorine bleach disinfectant, 5.25%, 0.75 cup per gallon of water
CAUTION: Do not apply isopropyl alcohol to the Monitor - some parts
can become marred and cracked.
Isopropyl alcohol (for accessories only)
Cidex Formula 7 (registered trademark of Johnson & Johnson Medical
Products, Inc.) or pHisoHex (registered trademark of Winthrop-Breon
Laboratories)
Quaternary-based germicidal detergents like VESTAL INSURANCE (registered
trademark of the Vestal Corp.), HI-TOR PLUS (registered trademark of the
Huntington Corp.), or VIREX (registered trademark of S.C. Johnson & Son
Corp.)
For the above, follow manufacturers' recommendations for dilution rate and
use. These recommendations are not an endorsement of the manufacturers or
of the effectiveness of these materials for cleaning or disinfecting.
4.3.1.4 Long-Term Storage
If it becomes necessary to store the Monitor for an extended period of time,
remove all attached accessories. Attach the original packing inserts, and place
the monitor into the original shipping container.
Generally, long-term storage of a nickel-metal hydride battery in either a
charged or discharged condition has no permanent effect on capacity. Capacity
loss due to self-discharge is reversible, and nickel-metal hydride batteries can
recover to full capacity by proper recharging. For example, cycling through
repeated charge/discharge cycles can restore a full capacity of a nickel-metal
hydride battery that was stored at room temperature for up to one year.
Long-term storage at high temperatures can lead to deterioration of seals and
separators and should be avoided.
4.3.2 Annual Procedures
Perform the test procedures described in paragraph 4.7 every twelve months, or
whenever the accuracy of any reading is in doubt.
4-8
Note: An internal, 3.6V NiMh battery acts as an alarm backup and maintains the
nonvolatile RAM memory when the Monitor is off or away from AC mains.
A system alarm message will be generated if backup battery replacement
is required.
4.4 CARE OF STORAGE BATTERIES
The Monitor uses one nickel-metal-hydride (NiMH) storage battery. The battery can
be charged at any time without reducing the charging capacity.
4.4.1 Procedures For First Use
Follow these procedures to condition a new NiMH battery and optimize its
performance:
The internal battery will automatically charge when the AC power supply is in use.
When the battery is charged for the first time, the charger may indicate
prematurely that charging is incomplete. This is normal and can happen with all
rechargeable batteries when first charged.
4.4.2 Battery Charging
The Monitor charges the NiMH battery whenever the AC power supply is in use.
The Monitor automatically senses if the battery needs recharging. Battery
charging will continue as long as the Monitor is connected to the AC power
supply, even when the Monitor is turned off.
• Batteries should be charged before first use or after prolonged periods of
storage.
• The battery should be charged before use, as a charged battery loses
some charge when left in storage.
• The battery should be charged at room temperature (59° F - 86° F; 16° C 30° C).
• It is normal for the battery to become warm during charging or after use.
• Batteries can be charged or topped-off at any time. It is not necessary to
wait until they are fully discharged.
• If the monitor is idle for extended periods, it should be fully charged once a
month to ensure optimum performance.

4.7.6 Battery Tests
From within the Service Menu, battery status information is displayed on the right
upper 1/4th of the display.
Battery/ Power Supply menu
1. Battery Health: the Monitor’s software approximates the true status of the
battery’s health. The value indicated is displayed as both a number (in
percentage) and as an icon on the bottom-left area of the display.
2. External Supply available: True indicates a source other than the internal
battery is providing power for the monitor, and a source to charge the
internal battery.
3. External Supply Sufficient to Charge: If the voltage from the external supply
is greater than that of the internal battery, the monitor will display the results
as TRUE. False will result if either the voltage is equal to or lower than the
power available from the internal battery.
4. Charge Type: Fast or Slow.
5. Battery Failed: Any result other than FALSE, indicates that the internal
battery has suffered a failure and should be investigated.
4-31
6. Charger Supply Enabled: Should always be TRUE as the monitor
consistently attempts to keep the battery at its’ fullest capacity. A FALSE
indicates the battery may be faulty or not installed, or the charge circuit may
have failed. Also, if no external source of power is available, the monitor will
register a FALSE result.
