Bi-Level Machine

A Bi-Level machine is a positive airway device that can be set to two distinct pressure settings. The inhalation setting, (IPAP), is adjusted to relieve snore and hypopnea. The exhalation pressure, (EPAP), is adjusted to relieve apnea.

Bi-Level devices are commonly used when a patient cannot tolerate the pressure of a CPAP. Used for this purpose, the Bi-level machines are set to run in Spontaneous Mode. Spontaneous referring to the presence of respiratory drive.

A Bi-Level set to run in Timed Mode, are used for patient’s with a host of medical issues, including Central Apnea, ALS, and many forms of COPD. The timed Bi-Level will initiate a breath, when respiratory drive is not present.
