Page 8: Functional Description
Datex-Ohmeda S/5 monitors FUNCTIONAL DESCRIPTION 2.1 Measurement principle 2.1.1 Cardiac output and REF Cardiac output measurement is made using the principle of thermodilution. During measurement the catheter lies in the heart, with an injection port in the right atrium (RA) and a thermistor, which is to monitor blood temperature, in the pulmonary artery (PA). -

Page 10: Invasive Blood Pressure Measurement
Datex-Ohmeda S/5 monitors 2.1.3 Invasive blood pressure measurement To measure invasive blood pressure, a catheter is inserted into an artery or vein. The invasive pressure setup, consisting of connecting tubing, pressure transducer, an intravenous bag of normal saline all connected together by stopcocks, is attached to the catheter. The pressure transducer is placed at the same level with the heart, and electrically zeroed. -

Cardiac Output Modules, M-COP and M-COPSv Uout = Uin x Pressure x 5 V, where Uin = 5 V Þ Uout = 25 V x Pressure [mmHg] Pressure amplification is performed by the instrumentation amplifier. The gain of the amplifier is set so that the level of the signal transferred to the A/D converter stays within the measurement range even when there are circumstantial offsets or offsets caused by the pressure transducer. -
