for Her masks referred to collectively as AirFit N20 throughout

Using this guide

Please read the entire guide before use. When following
instructions, refer to the images at the front of the guide.

Intended use

The AirFit N20 channels airflow non-invasively to a patient
from a positive airway pressure (PAP) device such as a
continuous positive airway pressure (CPAP) or bilevel device.
The AirFit N20 is:
•
to be used by patients weighing more than 30 kg for
whom positive airway pressure has been prescribed
•
intended for single-patient re-use in the home
environment and multi-patient re-use in the
hospital/institutional environment.
WARNING
Magnets are used in the lower headgear straps and the
frame of the AirFit N20. Ensure the headgear and frame is
kept at least 50 mm away from any active medical implant
(eg, pacemaker or defibrillator) to avoid possible effects
from localised magnetic fields. The magnetic field strength
is less than 400 mT.
Contraindications
Use of masks with magnetic components is contraindicated in
patients with the following pre-existing conditions:
• a metallic hemostatic clip implanted in your head to repair
•
metallic splinters in one or both eyes following a
penetrating eye injury.

GENERAL WARNINGS

•
The vent holes must be kept clear.
• The mask should only be used with CPAP or bilevel
devices recommended by a physician or respiratory
therapist.
• The mask should not be used unless the device is
turned on. Once the mask is fitted, ensure the device is
blowing air. Explanation: CPAP and bilevel devices are
intended to be used with special masks (or connectors)
which have vent holes to allow continuous flow of air
out of the mask. When the device is turned on and
functioning properly, new air from the device flushes
the exhaled air out through the mask vent holes.
However, when the device is not operating, insufficient
fresh air will be provided through the mask, and the
exhaled air may be rebreathed. Rebreathing of exhaled
air for longer than several minutes can, in some
circumstances, lead to suffocation. This applies to
most models of CPAP or bilevel devices.
•
Follow all precautions when using supplemental
oxygen.
