72. O gas absorbs certain wavelengths of infrared energy with the amount depending on the amount of CO gas A detector outfitted with an infrared bandpass filter only allows a certain wavelength of infrared energy that the CO gas absorbs As the CO concentrations in the sampled air passes through the sample cell the detector senses the infrared energy changes and converts them to an electrical signal This electrical signal is then amplified and conditioned and sent to a microprocessor for processing and then sent to a display The CO Board also uses a reference channel The purpose of this reference channel is to cancel the effects of IR source changes sample cell contamination temperature etc The only difference from the CO channel is that the detector is outfitted with an optical filter that is tuned to a band in the infrared spectrum that is transparent to CO and other gases typically found in the medical industry The signal from the reference channel is processed similarly to that of CO measurement channel Poet Plus 8100 Service Manual Page 3 3 Section 3 Theory of Operation Galvanic Oxygen Sub Module 02 Temperature Communications Printer Page 3 4 The CO and reference detectors work by an effect known as pyroelectric Pyroelectric effect works by changing energy levels either increasing or decreasing that are imposed on a sensing element The detector is outfitted with an optical bandpass f

Once the metal is used up the depleted cell can no longer sense oxygen The cell generates a voltage output proportional to the amount of oxygen in the sampled gas This oxygen cell has an internal thermistor and circuitry that adjusts the output voltage based on current temperature of the cell The voltage is read by the microprocessor and an O measurement is generated using predictive circuitry This predictive function enhances response time of the O monitoring module The relationship between gas concentration and pressure is calculated by the microprocessor The monitor displays the numerical value O2 Calculated generated using the following formula 20 9 uke O Calculated O Measured x O Ambient P The measured O predictive value is multiplied by a fixed value derived from room pressure divided by room ambient oxygen levels The measurement is further adjusted by multiplying the ratio of the pressure determined at calibration P with the current pressure Po There is a negligible effect on O measurements due to humidity The O function is appropriate for measuring respiratory Oo concentrations in all patient populations The O monitor is suitable for use in breathing systems and with the use of inhalation anesthetic agents The oxygen cell contains temperature correction circuitry The oxygen sensor temperature is maintained at a nominal 40 degrees Celsius to maintain a consistent performance Poet Plus 8100
