# Table of modes of mechanical ventilation

There are many modes of mechanical ventilation. 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)

| Mode | Trigger | Limit | $I_{cycle}$ | $P_{cycle}$ | 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 |
| $SIMV+P_S$ (volume cycled) | V or P | Flow | Volume | - | no |
| $SIMV+P_S$ (pressure limited) | V or P | Pressure | Time | - | no |
| $C_{PAP}$ | P | Pressure | Flow | - | no |
| $C_{PAP}+P_S$ | P | Pressure | Flow | - | no |
| $B_{PAP}$ 1 $(C_{PAP+PS})$ | P | Pressure | Flow | - | no |
| $B_{PAP}$ 2 (PCV) | V or P | Pressure | Timed | - | no |
