14. Input Signal Path Refer to 2752 03 schematic sheet 5 The signals from the sensor CO2DATAIN Data and CO2REFIN reference signal have similar signal paths The CO2DATAIN passes through a high pass filter with a gain of 3 8 consisting of C80 R148 and buffer amplifier IC21B The signal is fed to a Butterworth low pass filter IC21A and associated components This filter has a gain of 2 with a corner frequency of 1 5 KHz The output from the low pass filter is fed to a 12 bit digital to analog converter IC22 The signal CO2DIN comes into the reference of the DAC which acts as a programmable gain stage followed internally by an amplifier with a fixed gain of 2 Here under processor control the signal s gain is adjusted to an acceptable level for conversion The gain setting is adjusted using the digitized signal out of the A D Converter IC6 as part of the feedback loop Similarly CO2REFIN is conditioned by high pass filter IC21D with a gain of 1 75 and low pass filter IC21C with a gain of 2 The equivalent fixed gains for the two input signals are not equal in order to compensate for differences in the output signal levels of the infra red detectors in the sensor The output from IC22 is buffered by IC24A and AC coupled through C91 to IC23A The CO2DATAIN signal received from the sensor is ac coupled prior to the initial gain stage and high pass filtered to remove any DC bias by C80 Prior to sampling CO signal the CO2AZ

U to regulate the output pulses from the TPU The TPU PWM signal is buffered by MOSFET Driver IC19A and capacitively coupled to the gate of the heater drive MOSFET Q9B Capacitive coupling the signal prevents a system fault that would allow the PWM to be stuck at a level that would cause too high of a heater output In the absence of a pulse the gate drive will be pulled high disabling the output to the heater The pulsed voltage signal out of the MOSFET is filtered by D12 L6 C68 and C69 to produce a DC output level for the heater Since the TPU generated PWM signal is based on the system clock it is synchronized with the generation of the source pulse timing This minimizes the effect of any random disturbance caused by the heater circuit on the detection of the data and reference signals The error voltage out of amplifier IC18A also appears at the temperature watchdog comparator IC17C If the error voltage reaches a voltage equivalent to 56 degrees Celsius the comparator trips turning Q10 off The gate of MOSFET is pulled high by R116 which turns it off and VHTR is prevented from reaching the source of transistor Q9B The temperature of the sensor Model 710 715 Service Manual 13 Section 2 Theory of Operation is also monitored by the MPU which will disable the heater when a temperature of 50 degrees Celsius is exceeded To shut off the heater the MPU asserts the CASEOT signal turning Q11 on which turns Q10 and Q9A off CO

105. which has endured and evolved in the clinical setting for over two decades and remains the most popular and versatile technique today The principle is based on the fact that CO molecules absorb infrared IR light energy of specific wavelengths with the amount of energy absorbed being directly related to the CO concentration When an IR beam is passed through a gas sample containing CO the electronic signal from the photodetector which measures the remaining light energy can be obtained This signal is then compared to the energy of the IR source and calibrated to accurately reflect CO concentration in the sample To calibrate the photodetector s response to a known concentration of is stored at the factory in the monitor s memory A reference channel accounts for optical changes in the sensor allowing the system to remain in calibration without user intervention 5 TIDAL WAVE Sp determines oxygen saturation using sensors that contain red and infrared 660 and 940 nanometer light sources called light emitting diodes LEDs The light energy from each LED is beamed through a tissue sample a pulsating vascular bed such as the patient s finger or toe The remaining light energy not absorbed by the tissue sample reaches a photodiode light receptor in the sensor Oxygen saturated blood absorbs different amounts of light at each wavelength as compared to desaturated blood Therefore the amount of light absorbed by the blood
