patient spontaneous efforts that trigger the ventilator, e360 delivers
breaths with a constant pressure equal to PEEP/CPAP + Pressure
Support until the end of patient inspiration which is determined by
the attainment of one of the three cycling off thresholds. The breaths
are delivered according to the user-selected settings for Pressure
Support, Slope/Rise, and PEEP/CPAP.
Pressure Support breaths are cycled off based on attaining one of
threethresholds:apercent(%)ofpeakow(usersetviaExpiratory
