• Auto-PEEP is an incomplete expiration previous to the initiation of the following breath reasons modern air trapping (hyperinflation). This accumulation of air will increase alveolar pressure at the stop of expiration, that’s known as auto-PEEP.

• Auto-PEEP develops usually in excessive minute ventilation (hyperventilation), expiratory drift trouble (obstructed airway) and expiratory resistance (narrow airway).

• Once automobile-PEEP is recognized, steps need to be taken to forestall or lessen the strain construct-up. When vehicle-PEEP persists despite control of its underlying motive, implemented PEEP may be helpful if the patient has an expiratory waft drawback (obstruction).
