What is VPAP/BiPAP Machine?

BiPAP stands for BiLevel Positive Airway Pressure and is very similar in function and design to a CPAP machine. Unlike a CPAP machine which delivers a constant standard pressure, a BiPAP machine has two pressure settings. One pressure is for inhalation (IPAP) and a lower pressure for exhalation (EPAP). When you breathe in, the pressure will increase to the prescribed amount, and lower during exhalation. Many people cannot tolerate CPAP therapy and have been prescribed this specific therapy by their physician. Other names for bilevel machines include BiPAP and VPAP.

These machines carry all of the same features and benefits of CPAP. It is best to talk with your physician before purchasing a BiPAP or VPAP machine, as these are often used to treat more severe cases of sleep apnea, or cases complicated by other respiratory illnesses. All BiPAP or VPAP machines are medical devices and require a prescription prior to purchase.

How do I prevent excessive gas and abdominal bloating while using a BiPAP?

Excess gas and abdominal bloating are common complaints among some BiPAP users. This happens when air is inadvertently swallowed while using the BiPAP machine. To get rid of the gas and bloating, simply elevate the level of your head prior to falling asleep. If the problem still persists, consult your physician for advice.

How often should I clean a BiPAP machine's tubes and hoses?

You should clean your BiPAP machine’s hoses and tubing once a week with a solution of mild liquid dish soap and distilled water. Let them air dry completely after rinsing thoroughly.
