Using Your Mask - ResMed AirFit N20 User Manual

• As with all masks, some rebreathing may occur at low CPAP
pressures.
• Refer to your CPAP or bilevel device manual for details on
settings and operational information.
• Remove all packaging before using the mask.
• The mask must be used under qualified supervision for users who
are unable to remove the mask by themselves.
• This mask is not for use on patients with impaired laryngeal
reflexes or other conditions predisposing to aspiration in the
event of regurgitation or vomiting.
• Avoid connecting flexible PVC products (eg, PVC tubing) directly
to any part of the mask. Flexible PVC contains elements that can
be damaging to the materials of the mask, and may cause the
components to crack or break.
• The mask contains an exhaust port safety feature to enable
normal breathing. The mask should not be worn if this safety
feature is damaged or missing.
