Table of modes of mechanical ventilation

There are many modes of mechanical ventilation.^[1] In medicine, mechanical ventilation is a method to mechanically assist or replace spontaneous breathing.

A breath by breath trigger, limit, cycling (TLC) classification of the common modes of ventilation. (V = ventilator; P = patient)^[2]

Mode	Trigger	Limit	Icycle	Pcycle	Servo
CMV (VCa, AC)	V or P	Flow	Volume	Time	no
PCV or PCIRV	V or P	Pressure	Time	Time	no
SIMV (volume cycled)	V or P	Flow	Volume	-	no
SIMV (pressure limited)	V or P	Flow	time	-	no
SIMV+PS (volume cycled)	V or P	Flow	Volume	-	no
SIMV+PS (pressure limited)	V or P	Pressure	Time	-	no
CPAP	P	Pressure	Flow	-	no
CPAP+PS	P	Pressure	Flow	-	no
BPAP 1 (CPAP+PS)	P	Pressure	Flow	-	no
BPAP 2 (PCV)	V or P	Pressure	Timed	-	no
BPAP 3 (CPAP)	V	Pressure	Time	-	no
BPAP 4 (SIMV)	V or P	Pressure	Time (IV) Flow (IP)	-	no
BPAP 5 (APRV)	V or P	Pressure	Flow (IP) Time (IV)	-	no
APRV	V or P	Pressure	Flow (IP) Time (IV)	-	no
IMPRV	V or P	Pressure	Time	-	no
