➡️ Control Mode Ventilation (CMV)
It's a mode where the ventilator delivers a preset tidal volume at a set time-triggered frequency. So basically, the ventilator controls both the rate and tidal volume which means that it's in total control of the minute ventilation.

➡️ Airway Pressure Release Ventilation (APRV)
It's a mode in which two levels of continuous positive airway pressure are applied with an intermittent release phase for spontaneous breaths.

➡️ Mandatory Minute Ventilation (MMV)
This is a feature of some ventilators that causes an increase in the mandatory breaths that are delivered when the patient’s spontaneous breathing level becomes inadequate.

➡️ Inverse Ratio Ventilation (IRV)
This is a mode that uses an inverse I:E ratio to improve oxygenation and gas exchange. It’s been shown to decrease shunting, improve V/Q mismatching, and decrease deadspace ventilation.

➡️ Pressure Regulated Volume Control (PRVC)
A mode of mechanical ventilation that provides volume-controlled breaths with the lowest pressure possible. It does so by altering the flow and inspiratory time.

➡️ Proportional Assist Ventilation (PAV)
This is a mode of mechanical ventilation where the machine uses variable pressure to provide pressure support for a patient’s spontaneous breaths.

➡️ Adaptive Support Ventilation (ASV)
It's a mode of ventilation that changes the number of mandatory breaths and pressure support level according to the patient’s breathing pattern.

➡️ Adaptive Pressure Control (APC)
This is a pressure-controlled mode that utilizes a closed-loop control of the pressure setting in order to maintain a minimum delivered tidal volume.

➡️ Volume-Assured Pressure Support (VAPS)
It's a mode of ventilation that provides a stable tidal volume by incorporating inspiratory pressure support ventilation along with conventional volume-assisted cycles.

➡️ Neurally Adjusted Ventilatory Assist (NAVA)
It's a mode that uses the patient’s electrical activity of the diaphragm to guide the functionality of the ventilator.

➡️ Automatic Tube Compensation (ATC)
While not technically a mode in my opinion, this is a setting on some ventilators that offsets and compensates for the airflow resistance that is imposed by the endotracheal tube.

➡️ High-Frequency Oscillatory Ventilation (HFOV)
A type of mechanical ventilation that delivers very small tidal volumes at an extremely fast rate which minimizes the chances of a lung injury.
