Hospital Mask
NON-VENTED FULL FACE MASK
The ResMed Hospital NV (non-vented) Full Face Mask is a disposable non-invasive
device used for channelling air flow with or without supplemental oxygen.
Intended Use
The ResMed Hospital NV Full Face Mask is intended:
•
to be used with active-exhaust-valve ventilator systems, to provide ventilatory
assistance to patients with respiratory insufficiency and respiratory failure.
•
to be used on adult patients (>30 kg), requiring non-life-support ventilatory
assistance.
•
for single-patient use, for a maximum of seven days, in the hospital or clinical
environment.
.
WARNINGS and CAUTIONS
•
This mask must not be used without qualified supervision for patients 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.
•
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 size selection and the mask leak.
•
If oxygen is used with the ventilator, the oxygen flow must be turned off when
the ventilator is not operating.
Explanation:
When the ventilator is not in operation, and the oxygen flow is left
on, oxygen delivered into the ventilator tubing may accumulate within the
ventilator enclosure. Oxygen accumulated in the ventilator enclosure will create
a risk of fire. This warning applies to most types of ventilators.
•
Please refrain from smoking while oxygen is in use.
•
Leak or variation in the leak may cause mistriggering of the ventilator.
•
In determining ventilator settings, and in particular the tidal volume for volume-
cycled ventilators, make appropriate allowance for mask dead space and leak.
•
As with all mask ventilation systems, significant leak may occur between the
mask and the patient's face. The leak may vary depending on such factors as the
patient ventilation, potentially producing profound hypoventilation or
hyperventilation. The magnitude of this effect depends on the ventilator's ability
to compensate.
