In medicine, a mechanical ventilators are "devices used to produce or assist pulmonary ventilation."[1] Mechanical ventilators may be used in surgery that is performed under general anesthesia or in critical care medicine for patients with respiratory insufficiency from causes such as acute respiratory distress syndrome.

Modes of mechanical ventilation include:

Acute respiratory distress syndrome

In the acute respiratory distress syndrome (ARDS) (P/F ratio < 200), better outcomes may occur with:

Weaning mechanicl ventilation

Details for weaning from mechanical ventilation are available.[6] Example criteria are if the PaO2:FIO2 ratio was greater than 150 mm Hg and FIO2 was no greater than 0.6.[4]
