Display Description
P PEEP The difference between the corresponding airway
tp
and esophageal pressures at the end of the
expiratory hold during an AutoPEEP maneuver.
Requires an inspiratory hold and esophageal
catheter.
MIP The maximum negative airway pressure that is
achieved by the patient, during an expiratory hold
maneuver.
P
The negative pressure that occurs 100 ms after an
100
inspiratory effort has been detected.

WOB Patient Work of Breathing (WOB
P
the total inspiratory tidal volume. Patient work of
breathing is defined as the summation of two work
components: work of the lung and work of the chest
wall. Requires an esophageal balloon.
WOB The work performed by the patient to breathe

spontaneously through the breathing apparatus, i.e.
the E.T. tube, the breathing circuit, and the demand
flow system. Requires a tracheal catheter.
