BPAP machines use pressure to push air into your lungs. Depending on the settings, this opens the lungs, improving the level of oxygen in the blood and decreasing the carbon dioxide. These 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).
