Test value:
Test O2 concentration using a separate O2
analyzer, e.g.
Oxydig
. The value indicated by
Savina must be 80 vol.% ±1 vol.%.
4.15.3
Testing trigger characteristics in CPAP/ASB
mode
Set the following values:
CPAP/ASB,
Paw alarm limit high = 30 mbar,
PEEP = 5 mbar,
O2 = 40 vol%,
ASB = 20 mbar,
Trigger = 3 L/min
Test set-up:
As in test step
4.15.1
.
Test value:
Unit does not trigger an ASB breath.
Simulate breathing.
Test value:
Trigger LED must light up and ASB breath
must be triggered. ASB pressure 25 mbar ±3
mbar.
