We have also provided BiPAP / CPAP service to our needful patient. Bi-PAP stands for bi-level positive airway pressure. It is one type of PAP, or positive airway pressure machine that is used to maintain a consistent breathing pattern at night or during symptom flare-ups in people with COPD. The machine pressurizes the air to a higher level than the air in the room, and so it helps a person to take in oxygen and exhale carbon dioxide. This helps them to breathe more easily, either while sleeping or when experiencing a flare-up of symptoms. BiPAP and CPAP, which stands for continuous positive airway pressure, are two often-used non-invasive ventilation (NIV) therapies. Both BiPAP and CPAP involve the person breathing pressurized air through a mask attached to a small machine. People using CPAP or BiPAP at night may experience longer and higher-quality sleep. Many people with COPD do not require a BiPAP machine, and the device does not work well for every person. A doctor will help someone decide whether it would be beneficial for them.
