What is a Bi-PAP or Bi-Level machine?
A Bi-PAP or Bi-Level machine uses two separate pressure settings for your therapy: An inspiratory pressure and an expiratory pressure. When you inhale, the therapy is delivered at the set inspiratory pressure, and then when you exhale, the pressure is delivered at the set expiratory pressure. The inspiratory pressure is always greater than the expiratory pressure. This type of machine is usually used for people who cannot tolerate a normal CPAP machine or for people who have other conditions along with their sleep apnea.
