Derivation
Highest airway flow measured during expiration
Highest airway flow during inspiration
Highest airway pressure during inspiration
Amount of pressure required to move gas at a flow
of one liter per second, derived from expiration
(P[end exp] - Pause) /Flow [end exp]
Represents the dynamic resistance to inspiratory
airflow created by the breathing circuit, ET tube,
and major airways of the lung
(P[end insp] - Pause)/Flow [end insp]
Average frequency of last 8 breaths
Respiratory rate divided by tidal volume for
spontaneous breaths, (RRs/TVs), for RRs
< 57 bpm
Duration of inspiration
Duration of expiration
Difference between expired and inspired tidal
volume expressed as a percent in mechanical
breaths (100 x [TVi m - TV e m] )/ TV i
Average volume calculated from difference of
expired volume and airway deadspace
TVe - TVd aw
Volume of CO
concentration of expired CO
inspired CO2 and multiplied by total expired
breath, compensated to STPD (Standard

TV alv X PeCO
Volume of breath not participating in gas exchange
measured during expiration
(ineffective tidal volume)
Tidal volume lost to airway deadspace divided by
Expired Tidal Volume during a spontaneous or
mechanical breath
