Timed Pressure Support; A Bi-level therapy mode where (BiPAP AVAPS device only) breaths are machine-triggered and machine-cycled. T mode provides mandatory pressure assist with bi-level pressures.
  • Page 10 Bi-Flex Comfort Feature If enabled, the device provides a comfort feature called Bi-Flex. The Bi-Flex attribute adjusts therapy by in- serting a small amount of pressure relief during the latter stages of inspiration and during active exhalation (the beginning part of exhalation). Bi-Flex levels of 1, 2, or 3 progressively reflect increased pressure relief that will take place at the end of inspiration and at the beginning of expiration.
