AZThese machines are called “bilevel” because they have two air pressure settings:
When you breathe in, BPAP machines deliver more air pressure. This is also known as inspiratory positive airway pressure (IPAP).
When you breathe out, the machine reduces the air pressure. This is called expiratory positive airway pressure (EPAP).
Some BPAP machines have a timer that can be programmed to maintain a certain number of breaths per minute.
How does a BiPAP machine differ from a CPAP machine?
BPAP and CPAP machines have a lot in common. They both deliver positive air pressure (PAP) via a tabletop device connected to a tube and a mask. They can sometimes be used to treat the same conditions, and have similar side effects.
The main difference between a BPAP and CPAP machine is how the air pressure is delivered:
BPAP machines deliver two levels of air pressure.
CPAP machines deliver a continuous level of air pressure.
CPAPs are typically the first treatment option for people with obstructive sleep apnea. The continuous pressure holds the airway open and there’s no need for two pressures.
