Delta AutoPEEP
AW
(dAutoPEEP

Delta AutoPEEP
AW
(dAutoPEEP
AW
), is the difference between airway pressure at the end of an
expiratory hold maneuver and the airway pressure at the start of the next scheduled breath after the
expiratory hold maneuver.

AutoPEEP
ES
AutoPEEP
ES
is defined as the difference between esophageal pressure measured at the end of
exhalation (PEEP
ES
) minus the esophageal pressure measured at the start of a patient-initiated breath
(P
ES start
) and the sensitivity of the ventilator’s demand system. The sensitivity of the ventilator’s demand
system is the difference between the baseline airway pressure (PEEP
AW
) and the airway pressure when
the patient initiates a breath (P
AW start
).

Transpulmonary Pressure, Plateau (P

Plat)
The ventilator is capable of calculating and displaying the Transpulmonary pressure during an inspiratory
hold, which is the difference between the airway plateau pressure (P
PLAT AW
) and the corresponding
esophageal pressure.
