  • Page 141: Functional Description

    Functional description FUNCTIONAL DESCRIPTION 2.1 Measurement principle 2.1.1 NIBP NIBP (Non-Invasive Blood Pressure) is an indirect method for measuring blood pressure. The NIBP measurement is performed according to the oscillometric measuring principle. The cuff is inflated with a pressure slightly higher than the presumed systolic pressure, and deflated at a speed based on the patient's pulse, collecting data from the oscillations caused by the pulsating artery.
  • Page 142 The oxygen saturation percentage SpO 2 measured by Datex-Ohmeda module is calibrated against the functional saturation SaO 2 func. The advantage of this method is that the accuracy of SpO 2 measurement relative to SaO 2 func can be maintained even at rather high concentrations of carboxyhemoglobin in blood.

They are of piezoresistive type. One is used for measuring the pressure of the blood pressure cuff and the pressure fluctuations caused by arterial wall movement (B1).
  • Page 147 Functional description Signal processing Two signals from the pressure transducers are amplified and sent to A/D converter. After the converter, digitized signals are sent to microprocessor for data processing. Before the converter, one of the signals is used to adjust the offset to the pressure safety level. The NIBP module is controlled with 80C51FA microprocessor at 16 MHz oscillator frequency.
  • Page 148 Datex-Ohmeda S/5 Light Monitor Valves Exhaust valves are used for emptying the cuff and the joining chamber after the measurement. Exhaust valve 1 is also used as safety valve in infant mode. Valve opens at 165 mmHg. Exhaust valve 2 is also used as safety valve in adult mode and opens at 320 mmHg.

    Functional description 2.2.3 LM-ECG board Patient signals are connected to overload protection circuits (resistors and gas-filled surge arresters) and analog switches to instrumentation amplifiers. Then the signals are amplified by 480 and limited by slew rate. Then they are A/D-converted, analyzed and transferred to module bus in digital form.
  • Page 150 Datex-Ohmeda S/5 Light Monitor Noise and pacemaker are detected by a slew rate detector. Lower frequency is determined by a high pass (HP) filter 0.5 Hz (monitor bandwidth). ECG filtering The Light Monitor has two ECG filtering modes: MONITORING 0.5 - 30 Hz (-3 dB, with 50 Hz reject filter) 0.5 - 40 Hz (-3 dB, with 60 Hz reject filter)
  • Page 151 Functional description Microprocessor section Microprocessor contains RAM and EPROM memories. The processor uses external EEPROM memory for storing intendifying data. The microprocessor's internal 8-channel A/D-converter converts the ECG-signals to digital form. Serial communication Communication with the LM module bus is made through RXD and TXD signals. See the principle of serial communication in next figure.

    Fix the mainstream sensor to the CO calibration airway adapter. Feed 5.00 % CO gas (e.g. Datex-Ohmeda Quick Cal Calibration Gas, order No. 755580) to the free end of the silicon tube (included in the kit P/N 902305). Introduce a steady stream of gas until FiCO and EtCO readings are same and observe the reading.
  • Page 219 Service procedures Possible causes of error Calibration should be performed using a CO calibration gas of a known concentration. To validate the concentration of the calibration gas, check by using several different sensors. If they are all consistently high or low, there is a good chance that the gas sample is suspect and another gas source should be tried.
