be used with special interfaces with connectors which have
vent holes (vent holes are located on the elbow) or separate
exhalation devices to allow continuous flow of air out of the
interface. When the flow generator is turned on and functioning
properly, new air from the flow generator will flush the exhaled
air out through the attached exhalation port. However, when
the flow generator is not operating (eg, power failure), not
enough fresh air will be provided through the system, and
exhaled air may be re-breathed. In this situation, remove the
Fealite immediately.
The exhaust vent flow is lower at lower system pressure (see
section “Technical Specifications” for Pressure-Flow Curve
details). If the system pressure during expiration is too low,
there may not be enough exhaust vent flow to completely flush
the air delivery hose of exhaled air before the start of the next
inspiration.
Discontinue using the Fealite if you frequently experience nasal
irritation, and consult your physician.
If oxygen is used with the flow generator, the oxygen flow must
be turned off when the flow generator is not operating.
Explanation of the Warning: When the flow generator is not in
operation, and the oxygen flow is left on, oxygen delivered into
the ventilator tubing may accumulate within the flow generator
enclosure. Oxygen accumulated in the flow generator
enclosure will create a risk of fire. This warning applies to most
types of flow generators.
Please refrain from smoking while oxygen is in use.
Note: At a fixed flow rate of supplemental oxygen flow, the inhaled
oxygen concentration will vary, depending on the pressure settings,
patient breathing pattern, interface selection and the leak rate.
