Physiological signal simulator
2. Test procedure
① IBP1 test:
Set the BP sensitivity of the ECG simulator to 5uv/v/mmHg, BP to 0mmHG, and the IBP
channel 1 to ART. Enter the IBP PRESSURE ZERO menu of the DPM4, zero Channel 1,
and then return to the main screen. Set the BP of the simulator to 200mmHg. Enter the IBP
PRESSURE CALIBRATE menu of the DPM4, conduct calibration, and then exit the IBP
PRESSURE CALIBRATE menu.
Set the BP value of the simulator respectively to 40mmHg, 100mmHg and 200mmHg. Then
the screen of the DPM4 should display 40±1mmHg, 100±2mmHg and 200±4mmHg.
Set the simulator output to ART wave. Then the screen of the DPM4 should display relevant
waveform properly.
Unplug the IBP probe. Then the screen should prompt “IBP: Transducer 1 OFF!” and “IBP:
Transducer 2 OFF!”
Plug the OHMEDA cable to the IBP1 channel. Then the prompting message “IBP:
Transducer 1 OFF!” disappears.
② IBP2 test:
Plug the IBP cable to the IBP2 channel, and repeat the procedure in Section ①.
