View source for Talk:Expiratory Pressure Relief (EPR)

'''EPR''' stands for Exhalation Pressure Relief.  When first connected to a CPAP machine, many users find it difficult to exhale.  CPAP machines provide ''continuous'' positive airway pressure, which makes it easier for the patient to inhale, but harder to exhale.  EPR lowers the pressure slightly when the patient is exhaling to help with this issue.  The level of EPR can be set to 1, 2, or 3; usually by the patient as it is most likely considered to be a comfort feature and shouldn't impact the effectiveness of the CPAP therapy.

Manufacturers of machines have their own brand names for EPR. Philips Respironics System One machines use the following terminology: C-Flex for their CPAP machines, Bi-Flex for their BiPAP machines, and A-Flex for their APAP machines.
