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 |
| PRVC[2] | V or P | Pressure | Time | - | Yes (VT) |
| Automode | V or P | Pressure | Flow (IP) Time (IV) | - | Yes (VT) |
| Volume Support[2] | P | Pressure | Flow | - | Yes (VT) |
| Minimum minute ventilation[2] | P | Pressure | Flow | - | Yes (VE) |
| Mandatory rate ventilation[2] | P | Pressure | Flow (IP) Time (IV) | - | Yes (Vf) |
| Proportional assist | P | Pressure/time | Flow | - | Yes (Flow+VE) |
| Mandatory minute ventilation[2] | V or P | Flow | Time | - | Yes (VE) |
