Patient Spirometry
Compact Airway Modules with the option
11. Enter the Spirometry service menu.
Connect a clean spirometry tube and D-lite to the module.
Perform the spirometry leak test.
12. Connect the sampling line. Breathe through the wider side of the D-lite. Check that the
flow waveform moves downwards when you breathe in, and upwards when you breathe
out.

General
For all Compact Airway Modules
•
Switch the monitor to standby and reassemble the module.
NOTE: Make sure that all front panel grounding claws are attached and have a good contact
with the module box.
NOTE: When reassembling the module, make sure that the tubes are not pinched between the
module box and internal parts.
13. Insert the Compact Airway Module into the frame. Switch the monitor back on and wait
until the message ‘Calibrating gas sensor’ disappears from the screen.
14. Block the tip of the sampling line with your finger and check that the message ‘Sample
line blocked’ appears on the monitor screen within 30 seconds.
15. Detach the D-fend and check that the message ‘Check D-fend’ appears on the monitor
screen within 60 seconds.

2.2.7 Single-width Airway Module, E-miniC
1. Wait until the message ‘Calibrating gas sensor’ disappears from the screen, then enter
the Gas Unit
General service menu.
2. Check that the Time-outs, Bad checksums and Bad c-s by mod values are not increasing
faster than by 5 per second.
3. Enter the Gases service menu: Check that the ‘Ambient’ value displayed corresponds with
the current ambient pressure (±20 mmHg).
4. Check that the flow measurement offset, i.e. the sample ‘Zero’ value displayed is within
±10 ml/min.
5. Perform a sampling system leak test.
6. Check the flow rates. Adjust the sampling flow, if necessary.
7. Block the tip of the sampling line with your finger and check that the message ‘Sample
line blocked’ appears on the monitor screen within 30 seconds.
Remove the Mini D-fend and check that the message ‘Check D-fend’ appears on the
screen within 30 seconds
.
8. Perform a gas calibration:
NOTE: For maximum accuracy, a warm-up time of 30 minutes is recommended.
