What does PEEP stand for?

PEEP stands for Positive End Expiratory Pressure. This is a critical concept in mechanical ventilation and respiratory therapy. PEEP is used to maintain a certain level of pressure in the airways at the end of expiration. This pressure prevents the collapse of the alveoli (tiny air sacs in the lungs) and enhances oxygenation by increasing functional residual capacity (FRC).

By keeping the alveoli open, PEEP can improve gas exchange and reduce the work of breathing. It's particularly beneficial in patients with conditions like acute respiratory distress syndrome (ARDS) or those who are mechanically ventilated, as it can help maintain oxygen levels and improve overall lung function. Understanding PEEP and its application is essential for effective patient management in both emergency and critical care settings.
