System Checks
22. Check that the inspired volume (VTI) on the fl ow measuring device is
500 ±50 ml.
23. Increase the tidal volume to 750 ml. Wait for the ventilator to stabilize.
24. Check that the inspired volume (VTI) on the fl ow measuring device is
750 ±75 ml.
If steps 20, 22 or 24 should fail, perform a PRAAA calibration ac-
cording to the instructions given in PSN: 076-9027-00.
25. Place the ventilator in Standby. Connect a pressure measuring device to
the inspiratory port of the absorber (Figure 41).

26. Set the bag/vent switch to Vent.
27. Ensure that the bellows is full.
28. Set the PEEP on the ventilator to 10 cmH
