The BiPAP mask is a necessary component of BiPAP therapy, and is used to distribute pressurized air from the machine to the user. The different pressures used during inhalation and exhalation with BiPAP can make it easier to get a good airflow and make the therapy more comfortable, if you use a comfortable mask that is fit properly. BiPAP masks come in a variety of styles such as nasal, nasal pillow and full face masks. This will be determined by the specific therapy prescribed, breathing pattern, sleeping position, facial structure, and comfort. When choosing a BiPAP mask, take into account size, cushion, headgear, seal, adjustability and compatibility with the BiPAP machine. A good mask – a well-fitted mask can help to reduce leakage and keep it more comfortable for everyday use. It is important to keep the mask, cushion and tubing clean on a regular basis and to maintain good hygiene. They should also be inspected for wear and tear and replaced if needed. The type and size of mask will depend on the individual therapy needs and can be recommended by a healthcare professional or sleep specialist.
