Bookmark or Share- Positive end-expiratory pressure: how to set it at the individual levelPEEP improves oxygenation through two possible mechanisms: (I) keeping open previously collapsed and perfused regions, causes an intra-pulmonary right-to-left shunt (venous admixture) decrease; (II) decreasing the cardiac output, generates a reduction of intra-pulmonary right-to-left shunt.
- Positive End-Expiratory Pressure (PEEP) • LITFL • CCC VentilationOVERVIEW. Positive End-Expiratory Pressure (PEEP) is the maintenance of positive pressure (above atmospheric) at the airway opening at the end of expiration. PEEP acts to distend distal alveoli, assuming there is no airway obstruction. PEEP is routinely used in mechanical ventilation to prevent collapse of distal alveoli, and to promote ...
- What Is Positive End-Expiratory Pressure (PEEP)? - Verywell HealthPositive end-expiratory pressure (PEEP) is a treatment option for patients who are experiencing acute respiratory failure (having trouble breathing on their own). Acute respiratory failure can occur after surgery, a lung injury, as the result of an infection, or a blockage in the lungs caused by a pulmonary embolism (blood clot in the lungs).
- American Journal of Respiratory and Critical Care MedicineHigher PEEP can improve arterial oxygenation, reduce tidal lung stress and strain, and promote more homogenous ventilation by preventing alveolar collapse at end expiration. However, PEEP may also cause circulatory depression and contribute to ventilator-induced lung injury through alveolar overdistention.
- Positive End-Expiratory Pressure - StatPearls - NCBI BookshelfPositive end-expiratory pressure (PEEP) is the positive pressure that will remain in the airways at the end of the respiratory cycle (end of exhalation) that is greater than the atmospheric pressure in mechanically ventilated patients.
