Auxiliary Oxygen Flowmeter
The auxiliary oxygen flowmeter delivers a metered
flow of pure oxygen, used, for example in the deliv-
ery of oxygen through a nasal cannula. Auxiliary
oxygen can be used in any ventilation mode, in
Standby, or even if the machine is switched off.
The auxiliary oxygen flowmeter may be used to
provide supplemental inspired oxygen to a patient
under spinal, epidural, or other regional anesthesia.
It may also be used to enrich the inspired gas mix-
ture provided by a manually powered selfinflating
resusciator bag*.
z Test the auxiliary oxygen flowmeter. Adjust the
flow knob (1) and make sure the float moves
freely over the full range of the flowmeter.
When finishing oxygen therapy, make sure the flow-
meter is completely closed:
z Turn the flow knob (1) clockwise until it can no
longer be turned.
Only then the oxygen flow is completely off.
