If you have trouble breathing, a BiPap machine can help push air into your lungs. You wear a mask or nasal plugs that are connected to the ventilator. The machine supplies pressurized air into your airways. It is called “positive pressure ventilation” because the device helps open your lungs with this air pressure.

Continuous positive airway pressure therapy (CPAP) uses a machine to help a person who has obstructive sleep apnea (OSA) breathe more easily during sleep. A CPAP machine increases air pressure in your throat so that your airway doesn't collapse when you breathe in.
