|---|---|---|---|
| Volume Controlled Continuous Mandatory Ventilation | VC-CMV | Mechanical ventilation with preset tidal volume and inspiratory flow. Every breath is mandatory (i.e.,inspiration is patient or machine trigged and machine cycled). | Assist/Control, A/C, CMV, Volume Assist/Control, Volume Control, Volume Limited Ventilation, Volume Controlled Ventilation, Controlled Ventilation, Volume Targeted Ventilation |
| Volume Controlled Intermittent Mandatory Ventilation | VC-IMV | Mechanical ventilation with preset tidal volume and inspiratory flow. Spontaneous breaths (i.e., inspiration is patient triggered and patient cycled) can exist between mandatory breaths. | Synchronized Intermittent Mandatory Ventilation, SIMV |
| Pressure Controlled Continuous Mandatory Ventilation | PC-CMV | Mechanical ventilation with preset inspiratory pressure and inspiratory time. Every breath is mandatory (ie, patient or machine trigged and machine cycled). | Assist/Control, A/C, CMV, Pressure Assist/Control, Pressure Control, Pressure Limited Ventilation, Pressure Controlled Ventilation, Pressure Targeted Ventilation |
| Pressure Controlled Intermittent Mandatory Ventilation | PC-IMV | Mechanical ventilation with preset inspiratory pressure and inspiratory time. Spontaneous breaths (i.e., inspiration is patient triggered and patient cycled) can exist between mandatory breaths. | Synchronized Intermittent Mandatory Ventilation, SIMV |
| Continuous Spontaneous Ventilation | CSV | Any mode of mechanical ventilation where every breath is spontaneous (i.e., patient triggered and patient cycled) | Spont |
| Mandatory Breath | None | A breath type during mechanical ventilation for which inspiration is machine triggered and/or machine cycled. | Machine breath, mechanical breath |
| Spontaneous Breath | None | A breath type for which inspiration is both patient triggered and patient cycled. Applies to assisted or unassisted breathing. | N/A |
| Assisted Ventilation or Breath | None | Ventilation or breath for which a machine provides some or all of the work of breathing. | Patient triggered ventilation or breath |
| Patient Triggered Breath | None | A breath that is initiated by the patient, independent of ventilator settings for frequency. | Patient assisted breath, assisted breath |
| Autotriggering | None | Unintended initiation of breath delivery by the ventilator, e.g., by an external disturbance such as movement of the breathing tube or an inappropriate trigger sensitivity setting. | Autocycling |
