Caution: Oxygen flow should always be supplied to maintain the reservoir bag to at least one third to one half full at end of inspiration. If the patients ventilation requirements cannot be met the mask should be removed.
Incurved nose seal which conforms to different nose shapes and prevents oxygen entering patient's eyes.
No metal nose clip so MRI compatible.
Clear mask for visibility of patient's nose and lips.
Soft face seals for patient comfort with improved sealing for higher oxygen concentrations.
Elastic strap can be placed above or below the ear to eliminate trauma to top of ears. Chin strap can similarly be placed under or on chin, for a better fit on a wider range of face shapes.
Two integrated safety valves which allows the patient to breathe room air in the event of oxygen supply failure.
