User Manual

Full Face Mask (F4)
Thank you for choosing BMC’s Full Face Mask (F4). The mask is comfortable, flexible, and quiet. It is designed to minimize contact with your face, thus ensuring that you feel comfortable during therapy. This user manual provides you with the information you need for the correct use of your mask.
The Mask is not made with natural rubber latex.

Intended Use

The Full Face Mask (F4) channels airflow non-invasively to a patient from a positive airway pressure device such as a continuous positive airway pressure (CPAP) or bi-level system.
The Full Face Mask (F4) is:

• to be used by adult patients (> 66 lb / 30 kg) for whom positive airway pressure therapy has been prescribed.
• intended for single-patient re-use in the home environment and multi-patient re-use in the hospital/institutional environment.

CAUTION: In the US, Federal law restricts the sale of this device to sale by or on the order of a physician.
Contraindications
This mask should be used with caution for patients with the following conditions:

• Facial deformity.
• Injured facial skin will contact the mask during use.

Before Using the Mask

WARNINGS

• The vent holes must be kept clear.
• This mask should only be used with CPAP or bilevel devices recommended by a physician or respiratory therapist.
• Explanation of Warning: CPAP systems are intended to be used with special masks with connectors that have vent holes to allow a continuous flow of air out of the mask. When the CPAP machine is turned on and functioning properly, new air from the CPAP machine flushes the exhaled air out through the attached mask exhalation port. However, when the CPAP machine is not operating, enough fresh air will not be provided through the mask, and exhaled air will be rebreathed. Rebreathing exhaled air for longer than several minutes can, in some circumstances, lead to suffocation. This warning applies to most models of CPAP systems.
• At low CPAP pressures, the flow through the exhaled port may be inadequate to clear all exhaled gas from the tube. Some rebreathing may occur.
• To minimize the risk of vomiting during sleep, the patient should avoid eating or drinking for three hours before using the mask. This mask is not recommended if the patient is taking a prescription drug that may cause vomiting.
• Do not use the mask without the Non-Rebreathing Valve in place.
• Not applicable to the silicone-allergy user.
• This mask should not be used on patients who are uncooperative, obtunded, unresponsive, or unable to remove the mask.
• Follow all precautions when using supplemental oxygen.
• Oxygen flow must be turned off when the flow generator is not operating so that unused oxygen does not accumulate within the flow generator enclosure and create a risk of fire.
• At a fixed flow 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.
• The technical specifications of the mask are provided for your clinician to check if it is compatible with the flow generator. If it is used beyond technical specifications or used with incompatible devices, the seal and comfort of the mask may not be effective, optimum therapy may not be achieved, and leak, or variation in the rate of leak, may affect the function of the flow generator.
• Stop using the Full Face Mask (F4) and consult your physician or sleep therapist, if you have ANY adverse reaction to the use of the mask.
• Refer to your flow generator manual for details on settings and operational information.
• Remove all packaging before using the mask.
• Images shown here are indicative only. If there is an inconsistency between the image and the actual product, the actual product shall govern.

• Exposing any part of the system or tubing to direct sunlight or heat may cause deterioration.
• If any visible deterioration of a component is apparent (cracking, crazing, tears, etc), the component should be discarded and replaced.

Daily/After Each Use

• Disassemble the mask components according to the disassembly instructions.
• Thoroughly clean the separated mask components (excluding headgear), by gently rubbing in warm (approx. 30°C) water using mild liquid detergent for 10 min.
• Use a soft bristle brush to clean the vent.
• Rinse all components well with drinking-quality water and allow them to air dry out of direct sunlight.
• When all components are dry, reassemble them according to the reassembly instructions.
