Modes of mechanical ventilation

Modes of mechanical ventilation refer to the various mechanical ventilator strategies employed to deliver a breath in patients that require mechanical ventilation. The mode refers to the method of respiratory support. In general, mode selection is based on clinician familiarity and institutional preferences, since there is a paucity of evidence indicating that the mode affects clinical outcome. The most frequently used forms of volume-limited mechanical ventilation are intermittent mandatory ventilation (IMV) and continuous mandatory ventilation (CMV).
