Test value:
Test O2 concentration using a separate O2
analyzer, e.g.
Oxydig
. The value indicated by
Savina must be 40 vol.%
±
1 vol.%. Read out
Vte from "Values" menu of Savina.
*The measured expiratory Vt refers to the
patient’s lung conditions (BTPS).
4.15.2
Testing of pressure-controlled ventilation
Units with BIPAP option: continue with test
step 4.15.2.1. All other units: continue with
test step 4.15.2.2.
4.15.2.1
Testing the pressure controlled ventilation in
BIPAP mode
Set the following values:
BIPAP,
f = 6 1/min,
Paw = max,
PEEP = variable,
Pinsp = variable,
P
ASB
= 0 mbar,
O2 = 80 vol.%,
Tinsp.= 5 s,
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.
