WARNING
• The mask contains safety features, the exhaust vent holes and
anti-asphyxia valve, to enable normal breathing and exhaust
exhaled breath. Occlusion of the exhaust vent holes or
anti-asphyxia valve needs to be prevented to avoid having an
adverse effect on the safety and quality of the therapy. Regularly
inspect the vent holes and anti-asphyxia valve to ensure they are
kept clean, clear of blockages and are not damaged.
• Only use compatible CPAP or bi-level therapy devices or
accessories. The technical specifications of the mask are provided
for healthcare professionals to identify compatible devices. Use in
combination with incompatible medical devices can decrease the
safety or alter the performance of the mask.
• Regularly clean your mask and its components to maintain the
quality of your mask and to prevent the growth of germs that can
adversely affect your health.
• The mask must be used under qualified supervision for patients
who are unable to remove the mask by themselves. The mask
may not be suitable for those prone to aspiration.
• Discontinue using or replace this mask if the patient has ANY
adverse reaction to the use of the mask. Consult your physician or
sleep therapist.
• Follow all precautions when using supplemental oxygen.
• Oxygen flow must be turned off when the CPAP or bilevel device
is not operating, 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. This
warning applies to most types of CPAP or bilevel devices.
