NOTE
We recommend fully charging both the internal and the external battery before
starting a new ventilation.
5.3 Connecting the patient tube system

compliance in the ventilation tube system.

A patient filter (HME filter) should not be used together with an external patient gas
humidification system because this causes increased resistance.
