GENERAL WARNINGS
• Discontinue using this mask if you have ANY adverse reaction to the use of the mask,
and consult your physician or sleep therapist.
• Using a mask may cause tooth, gum or jaw soreness or aggravate an existing dental
condition. If symptoms occur, consult your physician or dentist.
• 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 N20 line of nasal CPAP masks are not intended to be used simultaneously with
nebulizer medications that are in the air path of the mask/tube.
• 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.
