6.4 Inspiratory and Expiratory Non-return
Valve Test
1 Detach the hose connectng the nspratory (1) and
expratory (2) connectors
2 heck that the adustable pressure lmtng (APL) valve (3)
s closed
3 Block the nspratory valve outlet (1) wth a sutable bung,
and nflate the reservor bag (not shown) wth a 2 L/mn
oxygen flow
4 Turn off the gas flow and check that the bag does not
empty by reverse flow through the expratory valve (2)
5 Remove the bung and attach a spare reservor bag to the
nspratory valve connector (1)
6 Turn on a 2 L/mn oxygen flow and fully nflate ths bag
(and the absorber reservor bag)
7 Turn off the gas flow heck that gas cannot be forced
through the nspratory valve by gentle squeezng of the
spare bag on the valve outlet
8 Remove the bag from the nspratory connector (1)
6.5 Bag/Ventilator switch test
1 Reft the breathng hose between the nspratory (1) and
expratory (2) connectors Set the bag/ventlator swtch (4)
to ‘Vent’
2 Set a flow of 10 L/mn and check that the bellows starts to
nflate
Ensure that the bag s not nflatng
3 Move the swtch (4) to Bag poston and watch the bag
nflate The bellows stops rsng
When the pressure reads 3 kPa (30 cmHO) turn off the
flow of gas
4 Select ventlator, the pressure on gauge should drop, but
the bag should reman nflated
5 Squeeze the bag, there should be no loss of pressure, and
the bellows must not rse
