Blinking red light
14.6 Pre-use check
Before connecting the Nomoline Family sampling line to the breathing circuit, do the following:
1. Connect the sampling line to the ISA gas inlet connector.
2. Check that the gas inlet connector is lit with a steady green light.
3. For ISA OR+:
Check that the O2 reading on the monitor is correct (21 vol%).
4. Breathe briefly into the sampling line and check that monitor displays a valid CO
waveform and valid values.
5. Occlude the sampling line with a fingertip and wait for 10 seconds.
6. Check that occlusion alarm is displayed on the monitor and that the gas inlet connector
shows a flashing red light.
7. If applicable:
Perform a tightness check of the patient circuit with the sampling line attached.
NOTE:
Variations in barometric pressure do not have any effects due to internal
barometric pressure compensation.
NOTE:
There are no adverse effects on stated performance due to cycling pressure of up to
10 KPa.
