Intended use

The mask is a noninvasive accessory used for channeling airflow (With or without supplemental oxygen) to a patient from a positive airway.

• Pressure (PAP) device such as a continuous positive airway pressure (CPAP) or bi-level system.
• The mask is to be used by patients (weighing>30kg), intended for single-patient reuse in the home environment.
• The mask is intended for single-patient use in the hospital or institutional environment.

Contraindications

If the user has the following diseases, the product may not be suitable for use.
Special attention should also be given when it must be used. In either case, it is up to the doctor to decide whether or not to use the mask. These diseases include:

• Recent eye surgery or dry eyes
• Glaucoma
• Hiatal hernia
• Impaired cardiac sphincter function, excessive reflux, impaired cough reflex
• Vomiting
• Bullous Lung Disease
• Pathologically Low Blood Pressure
• Bypassed Upper Airway
• Pneumothorax
• Diagnosed with acute sinusitis or otitis media
• At risk for aspiration of gastric contents
• Allergy or hypersensitivity to the mask materials, or on patients unable to remove the mask

CAUTION:
In the US, Federal law restricts the sale of this device to sale by or on the order of a physician.
WARNINGS

• Please read the entire guide before use.
• The vent holes must be kept clear.
• Explanation of Warning: CPAP systems are intended to be used with special masks with connectors which have vent holes to allow 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 of 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.
• 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 have ANY adverse reaction to the use of the mask.
• Refer to your flow generator manual for details on settings and operational information.
• As with all masks, some rebreathing may occur at low CPAP pressures.
• Remove all packaging before using the mask.

Parts of the mask

Fitting

Use a standard conical connector if pressure readings and / or supplemental oxygen are required.

1. Unclip one of the lower headgear clips from the frame.
2. Hold the mask steadily on your face and pull the headgear over your head.
3. Bringing the lower headgear straps below your ears, clip the headgear to the lower part of the frame.
4. Undo the fastening tabs on the upper headgear straps. Pull the straps evenly until they are comfortable and firm, and reattach the Velcro. Ensure that the mask fit well.
5. Undo the fastening tabs on the lower headgear straps. Pull the straps evenly until the mask is stable and comfortable. Reattach the fastening tabs.
6. Your mask and headgear should be positioned as shown in the illustration.

Note：
Connect the device air tubing to the swivel of mask and ensure it is firmly connected.
Removal
To remove the mask, disconnect one of the lower headgear clips and pull the mask and headgear up over your head.
CAUTIONS

• Do not remove the headgear until the clips is released
• Please confirm that you can remove the buckle and headgear freely

Disassembly

Notes:
The elbow assembly can may be incurred and the re-installation will become more difficult.

1. Detach the air tubing. Unclip the lower headgear clips and unhook the upper headgear Straps.
2. Gently separate the cushion from the frame.

Reassembly

1. Fit the cushion into the channel of the frame.
2. Threading the upper headgear straps through the loop of the frame. Keep the clips attached to the lower headgear straps and clip the headgear to the lower part of the frame.

Cleaning the Mask at Home
Notes:

• The mask and headgear can only be cleaned through hand washing.
• The elbow and the valve cannot be dissembled for washing.
• If any visible deterioration of a mask component is apparent (cracking, crazing, tears etc), the mask component should be discarded and replaced.

CAUTIONS

• Do not use solutions containing bleach, chlorine, alcohol, aromatics, moisturizers, antibacterial agents, or scented oils to clean any part of the system or air tubing. These solutions may cause damage and reduce the life of the product.
• Exposing any part of the system or tubing to direct sunlight or heat may cause deterioration.
• Do not use dishwasher to wash this mask.
• Do not the mask components to air dry in the direct sunlight as it may accelerate product aging.
• Do not iron the headgear. It may damage the headgear
• If cleaning is not done in accordance with the instructions (or increase the frequency of cleaning). May result in poor product performance or reduced product life.

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 soap.
• Use a soft bristle brush to clean the vent.
• To optimise the mask seal, facial oils should be removed from the cushion after use.
• Inspect each component and, if required, repeat washing until visually clean, making sure there is no soap residue.
• Rinse all components well with drinking quality water and allow to air dry out of direct sunlight.
• When all components are dry, reassemble according to the reassembly instructions.

Weekly

• Hand washes the headgear and all components in warm (approx. 30°C) and soapy water. Use pure soap. Rinse the components well and allow them to air dry out of direct sunlight.
• This action will age or damage the mask and shorten its service life. If any visible deterioration of a mask component is apparent (cracking, crazing, tears etc), the mask component should be discarded and replaced.
