An “occult” cause of electromechanical dissociation? Chest 99(2):492–493 22797452 ARDS Definition Task Force, Ranieri VM, Rubenfeld GD, Thompson BT, Ferguson ND, Caldwell E. Propofol and opioid will reduce respiratory drive and improve ventilator synchrony (but avoid prolonged high-dose exposure to these. Rogers PL, Schlichtig R, Miro A, Pinsky M (1991) Auto-PEEP during CPR. Consider high PEEP table if P/F is <200 mm (27 kPa), or in morbid obesity. Marini JJ (2011) Dynamic hyperinflation and auto-positive end-expiratory pressure: lessons learned over 30 years. Oxygenation Primarily determined by mean airway pressure (Paw) (as opposed to PEEP as commonly noted by early trainees). If the ventilator is set to control the pressure: it will control the left. Intrinsic PEEP, or auto-PEEP, is most commonly associated with inadequate expiratory times, collapse of small airways, or increased airway resistance. ![]() This review will focus on extrinsic PEEP, which is a ventilator setting that is controlled by the operator. The equation of motion is the basis for defining pressure control and volume control modes of ventilation. PEEP can be further defined as extrinsic or intrinsic. Lapinsky SE, Leung RS (1996) Auto-PEEP and electromechanical dissociation. for passive ventilation (no inspiratory effort on the part of the patient) is: P vent P elastic +P resistive P vent Elastance x Volume + Resistance x Flow 3. A meta-analysis that used the data from the aforementioned three trials found that higher PEEP levels were associated with improved survival in severe ARDS ( 35 ). Laghi F, Goyal A (2012) Auto-PEEP in respiratory failure. High PEEP resulted in improved oxygenation as well as more ventilator-free days and organ failure-free days however, mortality rate did not differ between PEEP arms. Kress JP, O’Connor MF, Schmidt GA (1999) Clinical examination reliably detects intrinsic positive end-expiratory pressure in critically ill, mechanically ventilated patients.
