'''Exhalation pressure relief''' is a [[CPAP]] feature that lowers the pressure on a CPAP machine when the patient exhales in an effort to make [[breathing ]] more comfortable. CPAP machines provide continuous positive airway pressure, making it easier for the patient to inhale, but harder to exhale. Exhalation Relief pressure relief generally offers three possible settings: '''1''', '''2''' or '''3''', with each number signifying the number of [[cmH2O]] of pressure reduction. (A setting of '''1''' provides the least pressure relief; a setting of '''3''' provides the greatest relief).

There are several brand-specific terms for Exhalation Reliefexhalation pressure relief. ResMed uses the term [[EPR]]. Philips-Respironics uses the term [[A-Flex]] for its APAP machines, [[Bi-Flex]] for its BiPAP machines, and [[C-Flex]] for its CPAP machines.
