Test step 8 is used to display the inspiratory flow "Flowinsp", the O
2
concentration "O2 (sensor 1)"
"O2 (sensor 2)" of the mixing chamber, and the O
2
supply pressure. In addition, each valve of the
valve block can be switched individually. With "O2 valve status" the valve (V7.1 through V7.8) can
be switched to "on", "off", or "pulsating" (100 ms "on", 200 ms "off). The respective valve can be
selected using the "O2 valve" function. The switching noise of the valves is clearly audible. The
expiratory valve is "sealed" with 10 mbar.

Test step 9 is used to display the expiratory flow "Flowexp" (S2), the expiratory pressure "Pawexp"
(S4.1), and the inspiratory pressure "Pawinsp" (S4.2). The expiratory pressure can be adjusted
(V3). The blower generates a constant flow of 10 L/min.
Trigger expiratory valve with > 5 mbar. The following measured values should be displayed:
−
”Flowexp” = 10 L/min ±1 L/min
−
”Pawexp” = ”Pawinsp” ±1.5 mbar
Connect (short-circuit) the inspiratory socket and the expiratory socket with a ventilation
hose to perform this test step.
