ResMed NV Elbow F20 User Manual page 3

GENERAL WARNINGS
• The mask, fitted with the NV elbow, should not be used unless the device is turned on.
• Follow all precautions when using supplemental oxygen.
• Oxygen flow must be turned off when the ventilator device is not operating (if used), so
that unused oxygen does not accumulate within the device enclosure and create a risk of
fire.
• Oxygen supports combustion. Oxygen must not be used while smoking or in the presence
of an open flame. Only use oxygen in well ventilated rooms.
• At a fixed rate of supplemental oxygen flow, the inhaled oxygen concentration varies,
depending on the pressure settings, patient breathing pattern, mask, point of application
and leak rate.
• If any visible deterioration of NV elbow is apparent (cracking, crazing, tears etc), the
component should be discarded and replaced.
• The technical specifications of the mask fitted with the NV elbow are provided to check that
the mask is compatible with the ventilator device. If used outside specification or if used
with incompatible devices optimum therapy may not be achieved.
• Discontinue using this mask if the patient has ANY adverse reaction to the use of the mask,
fitted with the NV elbow, and consult a physician.
• As with all masks, some rebreathing may occur at low pressures.
• Refer to the appropriate ventilator device manual for details on settings and operational
information.
• Avoid connecting flexible PVC products (eg., PVC tubing) directly to any part of the mask.
Flexible PVC contains elements that can be detrimental to the materials of the mask, and
may cause the components to crack or break.
• Always follow cleaning instructions. Some cleaning products may damage the mask, its
parts and their function, or leave harmful residual vapours.
• As part of good hygiene, always follow cleaning instructions to prevent the growth of
germs.
• Remove all packaging before use.
Note: For any serious incidents that occur in relation to this device, these should be reported to
ResMed and the competent authority in your country.
ResMed has tinted the NV Elbow F20 blue to identify it as a non-vented accessory. The elbow has a
standard female 22mm tapered fitting for external connection to the ventilator. Refer to the
Technical specifications section in this user guide for information about mask leak (pressure-flow),
deadspace and resistance.
Assembly
1. If the vented elbow is still assembled to the mask, squeeze the side buttons and pull the elbow
away from the frame.
2. Attach the NV Elbow F20 to the mask by pushing the elbow into the frame, ensuring it clicks in
and is firmly secured.
