Flush flow "expiration pressure measurement
R1"
The O2 concentration of the flush flow
corresponds to the set O2 concentration
(select respective flowmeter tube).
Switch on the unit. Remove the expiratory
valve.
Test set-up:
Test value:
The flush flow must be in the range
> 0.02 L/min and < 0.2 L/min.

Testing valves V8/V9 (emergency venting)
and tightness of "Emergency respiratory valve
D2"
Connect unit to test lung and adjust the
following parameters:
Operating mode = IPPV, AutoFlow OFF,
Pmax OFF,
Vt = 0.5 L,
Tinsp = 5 s,
f = 6 1/min,
O2 = 21%,
PEEP= 5 mbar,
Paw high = 10 mbar above peak pressure
Seal Spirolog sensor.
Test value (pressure curve shown on display):
Pressure build-up to "Paw-high limit", then
drop to < 6 mbar.
