Transpulmonary Pressure, AutoPEEP (P

PEEP)
Transpulmonary pressure, AutoPEEP (P
tp
PEEP) is the difference between the corresponding airway and
esophageal pressures at the end of the expiratory hold during an AutoPEEP maneuver.

Maximum Inspiratory Pressure (MIP)
Maximum Inspiratory Pressure (MIP), is the maximum negative airway pressure that is achieved by the
patient, during an expiratory hold maneuver.
