For F-LMP1 with the invasive blood pressure measurement
18. In the ESTP Module menu: Check that the “Cable” and “Probe” for P1 show OFF in the
Service Data field. Plug a cable with an invasive blood pressure transducer into the front
panel connector P1 and check that the “Cable” and “Probe” show ON and the
corresponding pressure waveform appears on the screen.
Perform the same check also for the InvBP channel P2.
"
19. Calibrate the InvBP channels P1 and P2 according to the instructions in the Technical
Reference Manual.
"
20. Check the InvBP channels with a patient simulator.
The settings and checks with Dynatech Nevada MedSim 300 Patient Simulator:
SENSITIVITY switch Ö 5 µV/V/mmHg
ECG – BASE – BMP Ö 60
BP – 1 - WAVE Ö ATM
BP – 2 - WAVE Ö ATM
Restore the normal monitoring screen by pressing the key
Normal Screen
.
Connect cables from the channels BP1 and BP2 to the module connectors P1 and P2. Zero
the InvBP channels by pressing the key ZERO ALL on the monitor front panel.
BP – 1 - WAVE Ö ART
BP – 2 - WAVE Ö CVP
Check that appropriate InvBP waveforms are shown and the InvBP values are approximately
120/80 (
±
3 mmHg) for the channel P1 and 15/10 (
±
2 mmHg) for the channel P2.
Check that HR value is calculated from P1 when ECG is not measured (ECG cable
disconnected).
"
SpO2 measurement
21. Check that the message “No probe” is shown when no SpO2 sensor is connected to the
module. Connect a SpO2 finger sensor to the module. Check that the message “Probe off”
is shown when the sensor is not connected to a finger.
"
22. Connect the SpO2 sensor onto your finger. Check that the reading of 95-99 and the typical
SpO2 waveform appear. Check that HR value is calculated from SpO2 when ECG and InvBP
(P1) are not measured.
