4.3.2 Low-pressure oxygen (LPO) inlet port
When using the LPO port, the amount of oxygen taken in by the Airvo 3 is controlled by an external
fl owmeter. Connect a tube from the external fl owmeter to the LPO port. Make sure that the fl owmeter
is turned off whenever the Airvo 3 is not delivering therapy.
When using the low-pressure oxygen inlet port, monitor the oxygen concentration displayed on the
Home screen. The oxygen fl ow-regulator must be adjusted manually to maintain the prescribed
oxygen concentration when changing the respiratory gas fl ow rate.
Clinicians may confi gure a High FiO
2
alarm to discourage use of high FiO
2
values in particular clinical
environments.
The High FiO
2
alarm can be disabled or a threshold between 30% and 95% can be selected when the
Airvo 3 is initially set up for your environment (see Oxygen high alarm threshold, Airvo 3 Technical
Manual). The alarm threshold is displayed on the Titrate FiO
2
