The Nasal Mask (N5) channels airflow non-invasively to a
patient from a positive airway pressure device such as a
continuous positive airway pressure (CPAP) or Bi-level system.
The Nasal Mask (N5) is:
• To be used by adult patients (> 66 lb / 30 kg) for whom
positive airway pressure therapy has been prescribed.
• Intended for single-patient re-use in the home
environment and multi-patient re-use in the hospital /
institutional environment.
• Nasal mask is a triangular in shape and sit on the face around the nose. • It held in place by head gear stretchy straps that go around nose. • The nasal mask covers the patient nose from the bridge to the upper limb area. • It deliver an indirect airflow to the airway to the nasal mask and its works for patient who need higher pressure settings. • It is most commonly used to provide relief to people with respiratory disorders. • It blows air into nose through a nose mask helping to keep the airway open while you sleep. • It prefer a more natural airflow.
