System setup, non-invasive ventilation
Risk of injury due to tube circuit and cable!
If laid incorrectly, the tube circuit or other cables (e.g. pulse
oximetry) could cause patient strangulation.
Ö
Tubes and cables must always be positioned so that they
cannot wrap around the neck or limbs of the patient.
Risk of suffocation due to closed exhalation valve!
If the opening of the exhalation valve is closed, the patient
could suffocate.
Ö
Make sure that the opening of the exhalation valve remains
open so that expired air can escape.
During non-invasive ventilation, the user must always be able to exhale (expire). This
can either be accomplished using a vented mask with integrated exhalation valve or a
non-vented mask with separate exhalation valve.
The exhalation valve is optionally available as an accessory.
