How to Read
Slope = compliance
Flat = stiff lung
Steep = compliant

LIP = lower inflection
UIP = upper inflection

Clockwise = normal
Counter = overdistension
APRV Physiology
P-High = CPAP level. Recruits alveoli. Patient breathes spontaneously here.

T-High = Time at P-High. Long (4-6s). The recruitment phase.

T-Low = Release time. SHORT (0.4-0.8s). Terminated at 75% of PEFR to prevent derecruitment.

P-Low = 0 in TCAV approach. Creates maximal release gradient.
