• It is expected that if the ventilator fails, the
mechanism of the ventilator will provide a low-
deadspace path to room air, so that significant
rebreathing does not occur. If the ventilator is
such that this is not the case:
• Prevention of rebreathing or total airway
obstruction (depending on the ventilator)
depends on the ability of the patient to open
his or her mouth.

• If the patient might fail to respond effectively
to failure of the ventilator by opening his or
her mouth and breathing through the mouth,
this mask should not be used.
• The mouth should never be taped or
otherwise limited from opening to an extent
which might compromise the patient's ability
to open his or her mouth.
• The mask should not be worn unless the
ventilator system is turned on and operating
properly.
• At a fixed rate of supplemental oxygen flow (if
used), the inhaled oxygen concentration will
vary depending on the pressure settings, patient
breathing pattern, mask selection and the leak
rate.
• The mask must not be used if the patient is
known to be allergic to any of the following mask
component materials: polycarbonate, silicone
rubber, polyurethane, nylon and polyester.
• Using a mask may cause tooth, gum or jaw
soreness or aggravate an existing dental condition.
If symptoms occur, consult your physician or
dentist.
