ECG/Resp Performance Test
This test checks the performance of the ECG and respiration measurements.
Tools required: Patient simulator.
ECG Performance
1 Connect the patient simulator to the ECG/Resp connector on the measurement server.
2 Configure the patient simulator as follows:
– ECG sinus rhythm.
– HR = 100 bpm.
3 Check the displayed ECG wave and HR value against the simulator configuration.
4 The value should be 100bpm +/- 2bpm.
Respiration Performance
1 Change the Patient Simulator configuration to:
– Base impedance line 1500 Ohm.
– Delta impedance 0.5 Ohm.
– Respiration rate 40 rpm.
Pump Check x4 = difference in pressure between cell pressure and ambient
pressure displayed on the monitor during occlusion (x4 >120
mmHg)
Flow Check x5 = difference between measured value and 50.0 ml/min
(x5<7.5 ml/min)
Noise Check x6 = noise index displayed on monitor (x6<3.0)
