Bi-Flex pressure relief technology offers pressure relief at inhalation and exhalation to make BiPAP therapy more like natural breathing. By tracking each breath, Bi-Flex pressure relief technology delivers pressure relief at three critical points in the breathing cycle:

1. the transition from exhalation to inhalation
   
2. the transition from inhalation to exhalation
   
3. during exhalation.
