external antennas) should be used no closer than 30 cm (12 inches) to any part of the BreathCare
PAP, including cables specified by the manufacturer. Otherwise, degradation of the performance
of this equipment could result.
yInterconnection of this equipment to other equipment which is not the supply one is forbidden.
yNebulisation or humidification can increase the resistance of breathing system filters and the
operator must monitor the breathing system filter frequently for increased resistance and blockage
to ensure the delivery of the therapeutic pressure.
yFailure to use a mask or accessory that minimizes rebreathing of carbon dioxide or permits
spontaneous breathing can cause asphyxiation.
yKeep device far away from the following environments, e.g. magnetic fields, electromagnetic
fields, external electrical influences, electrostatic discharge, pressure or variations in pressure,
acceleration, thermal ignition sources and so on.
yDo not block the several holes in your mask, otherwise it will result strangulation.
yHumidity performance of the device can be compromised when used outside the specified ambient
temperature range or humidity range.
yThe performance of the device can be compromised when exposed to environment, for example,
electrocautery, electrosurgery, defibrillation, X-ray(gamma radiation), infrared radiation, conducted
transient magnetic fields, magnetic resonance imaging (MRI), and radiofrequency interference.
yWhen the device is used near the children or disabled persons, the device must be supervised. Do
not let the children or disabled persons inhale or swallow small parts. Otherwise , it may result in
choking.
yKeep the area around the device dry, clean and clear of anything (eg, pets, pests or children) that
could affect the device hygiene, drop the device, and so on.
yThe device is intended for single patient use only. Do not let others use it.
4. Precautions
yUsing only YUWELL part and accessories with device. Non-YUWELL parts may reduce
effectiveness of the treatment and/or damage the device.
yUse only vented masks recommended by YUWELL or by your doctor with this device. Fitting the
mask without the device blowing air can result in rebreathing of exhaled air. Make sure that the
mask vent holes are kept clear and unblocked to maintain the flow of the fresh air into the mask.
yDo not use bleach, chlorine, aromatic-based solutions, moisturizing or antibacterial soaps or
scented oil to clean the device, water tank or air tube. Otherwise it may cause damage and reduce
the life of these products.
yIf you use the humidifier, always place the device on a level surface lower than your head to
prevent the mask and air tube from filling with water.
yLeave the water tank to cool for ten minutes before handling to allow the water to cool and to make
sure that the water tank is not too hot to touch.
yMake sure that the water tank is empty before transporting the device.
yThis equipment might not offer adequate protection to radio-frequency communication services.
The user might need to take mitigation measures, such as relocating or re-orienting the
equipment.
yThe proper placement and positioning of the mask on the face is critical to the consistent operation
of this equipment.
yNot intended for use with patient whose upper airways have been bypassed.
yThe time required for the device to warm from the minimum storage temperature between uses
until the device is ready for its intended use when the ambient temperature is 20 ℃ is about 2
hours.
yThe time required for the device to cool from the maximum storage temperature between uses until
the device is ready for its intended use when the ambient temperature is 20℃ is about 2 hours.
yThis device is not intended for children, and patients who are physically or mentally deficient can’t
use the device without assistance or supervision.
5. Adverse reactions
You should report unusual chest pain, severe headache, or increased breathlessness to
your prescribing physician. An acute upper respiratory tract infection may require temporary
discontinuation of treatment.
