State
Positive End-Expiratory
Pressure
PEEP
Average pressure during the End Expiratory
State
Mean Airway Pressure
MAP

Tidal Volume
Tidal Vol
Total volume accumulated over the Inspiratory
Time
Minute Volume
Minute Vol
Expiratory Tidal Volume times the respiratory
rate in breaths per minute; reported as an eight-
breath average
Peak Inspiratory Flow
Rate
PIF
Maximum of the absolute value of the Flow Rate
measured during the Inspiratory Time
Peak Expiratory Flow
Rate
PEF
Maximum of the absolute value of the Flow Rate
measured during the Expiratory Time
Compliance
N/A
Expiratory Tidal Volume divided by the difference
of the Inspiratory Hold Pressure and PEEP
