Test value:
Test O2 concentration using a separate O2
analyzer, e.g.
Oxydig
. The value indicated by
Savina must be 80 vol.%
±
1 vol.%.
Continue with test step
4.15.3
.
4.15.2.2
Testing the pressure controlled ventilation in
CPAP mode
Set the following values:
CPAP,
Apnea ventilation ON,
f
Apnea
= 10 1/min,
Vt
Apnea
= 2000 mL,
Paw = variable,
PEEP = variable,
O2 = 80 vol.%,
FlowAcc
=
60 mbar/s
Test set-up:
As in test step
4.15.1
.
In order to increase the O2 concentration faster, set the frequency to f = 12 1/min
and Tinsp = 2 s. As soon as the O2 concentration is reached, reset values as
specified previously.
