Positive End-Expiratory Pressure

Positive End-Expiratory Pressure (PEEP) is a respiratory support strategy used in patients with breathing difficulties, often in critical care. It involves maintaining pressure in the lungs at the end of exhalation, which helps keep the air sacs (alveoli) open. This can improve oxygen exchange and prevent the lungs from collapsing, making it easier for patients to breathe. PEEP helps ensure that a greater area of the lungs is available for gas exchange, enhancing overall lung function and oxygen delivery to the body.
