4.2 Theory of Operation
This chapter contains a high-level overview of the theory of operation of some major
functional components of the G30/G40 Patient Monitors.
4.2.1 System Overview
This chapter contains a system overview for the G30/G40 Patient Monitors,
including a high-level block diagram. This block diagram shows major components
of the monitor, including the power supply, NIBP control, SpO2 and CO2 processing,
and microcontroller. The monitor is a full function monitor for use on adult, pediatric,
and neonatal patients. The functions performed by the system include:
• Monitoring patient ECG, heart rate and respiration rate
• Blood pressure
• Blood oxygen saturation
• Carbon dioxide
• Temperature
In addition to monitoring and displaying the status of physiological parameters, the
monitor performs various microprocessor-programmed analytical functions,
including
• Creating both visual and audible alarm signals when settings are violated
• Creating and displaying warning messages when conditions are detected that
would degrade or prevent valid measurements
• Creating and displaying trend waveforms or tabular data
• Providing a synchronizing pulse for defibrillator operation
• Providing input to an optional recorder for printout of current or trend
waveforms or tabular data
The G30/G40 Patient Monitors operate from either an AC power source or battery
power. The monitor charges the battery when powered by AC.
4.2.2 Block Diagram Components
The G30/G40 Patient Monitors contain several major blocks, including:
• Functional module (including ECG, SpO2, NIBP, IBP/TEMP, CO2, Recorder)
• ARM Module
• Main Board assembly
• I/O module assembly
• AC/DC power module
4-3
Theory of operation
4.2.3 ARM Module
The ARM Module contains these components:
• ARM9 microprocessor
• Flash memory
• SDRAM
• Silicon Motion Multimedia Processor
• Connectors
–Display assembly
–Main Board assembly (wire to Main Board assembly)
–I/O module assembly (wire to I/O module assembly)
• USB
• Voltage regulator
4.2.4 Main Board Assembly
The system board contains a DC/DC voltage converter, which provides power and
communication to:
• IBP
• ECG
• SpO2
• NIBP
• IBP/Temp
• CO2
• Recorder
• ARM board
• Inverter
• AC/DC power module
• Speaker
• Keys
• Battery charging module
4.2.5 I/O Module Assembly
The output interface board provides the connector socket for the following
applications:
• Display output port
• Nurse call port
• USB Port
• Ethernet port
• ECG analog output port
4-4
Theory of operation
• Connection to the ARM Module
4.2.6 Speaker
The speaker is driven by an amplifier. The speaker provides the monitor’s audio
during alarm conditions. The microprocessor outputs different audio tones specified
by different alarm priorities and conditions.
4.2.7 Recorder
The recorder contains the following functions:
• Motor (paper drive) and driver circuitry
• Selectable print speed
–12.5mm/s, 25mm/s, Auto
• Selectable channel waves to print
Print head control logic is implemented on the Main Board. The microprocessor
sends data to the recorder via a serial port.
4.2.8 AC/DC Power Module
The G30/G40 Patient Monitors contain a medical grade power supply module and
circuitry that converts AC (100-240V) to DC (15V). Power consumption is 115 VA.
4.2.9 Keys and Navigation Wheel
The keys and navigation wheel generate pulses to the Main Board assembly during
use, and the Main Board assembly encodes the message to the ARM module, so the
patient monitor can respond to all kinds of operations.
4.2.10 NIBP Processing
The NIBP assembly and circuitry contain these elements:
• Pump
• Valves (2-valve system of dump and safety valve)
• Pressure measurement and control circuitry
Pressure data is converted to digital format and conveyed to the processor. The NIBP
pump uses an oscillometric method that employs stepwise pressure deflation. Pump
software eliminates most ambient noise and motion interference. Applications are
neonatal, pediatric and adult patients. The blood pressure range is: Systolic, 30-254
mmHg and Diastolic, 10-220 mmHg. Accuracy is Maximum Mean Error ±5 mmHg
4-5
Theory of operation
with Max. Standard Deviation 8 mmHg.
NIBP processing uses an oscillometric technique to provide needed measurements at
selected intervals. This technique uses an inflatable sphygmomanometer cuff similar
to those used by clinicians in routine measurements. A motorized pump inflates the
cuff to approximately 170 mmHg (adult mode) initially, at which point the pressure
effectively stops the flow of blood. Then, under monitor control, the pressure in the
cuff is gradually reduced, while a pressure transducer detects the pressure and
transmits the parameter signal to the NIBP input circuitry. As the pressure is reduced,
blood flows in the previously occluded artery, and changes the measurements made
by the transducer. The point at which oscillation increases sharply is defined as
systolic pressure. As the cuff continues to deflate, the oscillation amplitude increases
to a maximum, and then decreases. The peak oscillation amplitude is defined as the
mean arterial pressure. The point at which the system detects a rapid decrease in
oscillation is defined as the diastolic pressure.
4.2.11 SpO2 Processing
SpO2 is a measurement of oxygen saturation in the blood that uses an optical
spectrophotometry technique. It is based on the differences in the absorption of red
and Infrared light by oxygenated and de-oxygenated Hemoglobin. A pulse oximeter
passes red and infrared light into an arteriolar bed and measures changes in light
absorption during the pulsatile cycle. The light sources are red and infrared light
emitting diodes (LEDs). A photo diode provides detection. To identify the oxygen
saturation of arterial hemoglobin, the G30/G40 Patient Monitors use the pulsatile
nature of arterial flow. During systole, a new pulse of arterial blood enters the
vascular bed, and both blood volume and light absorption increase. During diastole,
blood volume and light absorption reach their lowest point. The measurement is
based on the difference between maximum and minimum absorption, focusing on the
pulsatile arterial blood. In addition to the oximetry function, the measurement can
also provide the heart rate.
4.2.12 ECG Processing
The monitor measures the patient's ECG signals by sensing the varying potential
difference between several points at the skin surface which respond to the
electro-chemical actions of the muscular activity of the heart. Up to five electrodes
are attached to the patient’s body. The varying potentials at these locations are sent
to the ECG circuitry. These signals are amplified and filtered and then digitized
before being transmitted to the microprocessor.
The microprocessor executes algorithms to:
• Calculate the ECG data
4-6
Theory of operation
• Compute the heart rate
• Detect a lead-off condition if one of the electrode connections is disrupted
• Detect the presence of pacemaker signals within the QRS waveform complex of
the ECG
• Generate an analog output for external use with defibrillators
Note —
The ECG analog output is available at a connector
on the back of the monitor.
4.2.13 IBP Processing
The invasive blood pressure (IBP) measurement produces real-time waveforms and
numeric values for systolic, diastolic, and mean arterial blood pressure. IBP
measurements use an A/D converter. An isolation transformer and opto-coupler
provide the required isolation between isolated and grounded chapters of the monitor.
Software algorithms filter typical artifacts like respiratory variation and pressure
changes caused by flushing the line or drawing blood samples.
4.2.14 Temperature Processing
Resistance temperature detectors (RTDs) measure temperatures using the physical
principle of the positive temperature coefficient of electrical resistance of metals.
The hotter they become, the larger – or higher –the value of their electrical resistance.
The advantage is stable outputs for long periods of time, ease of recalibration, and
accurate readings over relatively narrow temperature spans. The monitor’s input
circuitry conditions and processes the signal to drive the numeric display.
4.2.15 etCO2
The etCO2 module contains a:
• CO2 sensor assembly
• Flow system, including pump
• Signal processing PCB and peripherals
• Serial interface
• Power supply
• FRS (FilterLine Recognition Safeguard) to identify correct usage of a
MicroStream FilterLine®
• Input gas connector with FRS interface
The G30/G40 Patient Monitors use the Microstream® sidestream etCO2 method to
measure carbon dioxide (CO2). The sidestream measurement method samples the
respiratory gas with a constant flow from the patient’s airway and analyzes it with a
4-7
Theory of operation
remote CO2 sensor built into the monitor.
The CO2 measurement produces:
• A CO2 waveform
• An end tidal (etCO2) value: the CO2 value measured at the end of the expiration
phase
• An inspired minimum CO2 (InCO2) value: the smallest value measured during
inspiration
• An airway respiration rate (awRR): the number of breaths per minute,
calculated from the CO2 waveform
All infrared gas measuring instruments, including the CO2 module, consist of a
radiation source, a cell through which samples of gas flow and a detector that
transmits a signal related to the intensity of the radiation that is detected. The
quantitative aspects of photometric measurement are stated by the Beer-Lambert
law:
A = Log (Io/I) = εlc
Under carefully controlled conditions at a select absorption band, the absorbency of a
sample (A) is proportional both to the concentration of the sample (c) and the depth
of the absorbing layer (l). The molar extinction coefficient (ε) is a wavelength
dependent constant characterizing the sample. (Io) is the light intensity at zero
absorbency and (I) is the light intensity after some of the light is absorbed by the
sample. The CO2 module, as most continuous monitors of carbon dioxide, uses a non
dispersive infrared (NDIR) light source. All CO2 monitoring instruments, except
those manufactured by Oridion, that use a NDIR infrared light source, use the broad
band energy from a black-body source. A mechanical chopper modulates the light
beam and makes possible the monitoring of the sample, reference and dark signals
from which the concentration of carbon dioxide can be determined. The CO2 module
uses the energy generated by an infrared source that includes a proprietary gas filled
lamp and driver circuit. This energy contains only specific wavelengths which match
the absorption bands of the CO2. The CO2 module's infrared source is electronically
modulated by the driver circuit.
4.2.16 Power Management
The G30/G40 Patient Monitors contain a medical grade power supply module and
circuitry that converts AC (100-240V) to DC (15V). Power consumption is 115 VA.
The power management module contains:
• Lead-acid batteries
– 12 V, 2.3 AH
• Battery charger
4-8
Theory of operation
• DC/DC converter
The power management circuitry charges the battery through a battery charger(s).
Both the battery(s) and the AC/DC power module can power the system through
several DC/DC converters that provide various voltage outputs required by various
chips. Isolated transformers provide the power to the front ends floating area.
4.2.17 Nurse Call Contacts
The nurse call alarm contacts are available through a 3.5mm, miniature insulated
phone jack on the back of the unit. The alarm contacts close (open) for any alarm
condition detected by the monitor.
The alarm contacts are the three switching signals associated with a single pole,
double throw relay. These are the:
• Normally open contact (NO)
• Common contact
• Normally closed contact (NC)
Contact Rating of:
NO = 1A @ < 25Vac
Common contact = 1A @ < 60Vdc
Isolation of 1.5kV

A.1 Instructions for use
Medical electrical equipment can either generate or receive electromagnetic
interference. This product has been evaluated for electromagnetic
compatibility (EMC) with the appropriate accessories according to
IEC60601-1-2:2004, the international standard for EMC for medical
electrical equipment. This IEC standard has been adopted in the European
Union as the European Norm, EN 60601-1- 2:2004. Radio frequency (RF)
interference from nearby transmitting devices can degrade performance
of the product. Electromagnetic compatibility with surrounding devices
should be assessed prior to using the product.
Fixed, portable, and mobile radio frequency communications equipment can
also affect the performance of medical equipment. See your service
provider for assistance with the minimum recommended separation distance
between RF communications equipment and the product.
The cables, sensors/transducers, and other accessories for which compliance
is claimed are listed in this manual.
Warning
Use of accessories, transducers, and cables other than those specified may
result in increased emissions and/or decreased immunity of the G30/G40
Patient monitors.
G30/G40 Patient monitors should not be used adjacent to or stacked with
other equipment. If adjacent or stacked use is necessary, the monitor should
be observed to verify normal operation in the configuration in which it is
used.
Caution
The following ports on G30/G40 Patient monitors are sensitive to
electrostatic discharge during patient monitoring:
• SpO2
• ECG
Follow these guidelines to reduce electrostatic discharge:
• Do not touch the connector pins of the port.
• When connecting and disconnecting cables to the ports, use ESD
precautionary measures. Precautionary measures may include the
following:
– Make sure you are grounded prior to connection. Touch
grounded metal.
– Wear an ESD grounding strap and an ESD protective
garment.
–
Provide ESD training to all users. Users should understand
what electrostatic discharge is, how damage can occur, and
how to prevent ESD.
