PEEP
Also written as: PEEP — Positive End-Expiratory Pressure
Positive End-Expiratory Pressure; a ventilator setting that maintains pressure in the lungs at the end of expiration.
Full Definition
Positive End-Expiratory Pressure (PEEP) is a mechanical ventilation parameter that applies continuous positive pressure to keep alveoli open during expiration. This prevents alveolar collapse and improves oxygenation in patients with respiratory failure. PEEP is measured in centimeters of water (cmH2O) and is a critical setting that respiratory therapists monitor and adjust based on patient needs and physician orders.
Usage
Usage note: Always capitalize when used as acronym; lowercase when spelled out in running text.
In Context
- "The physician ordered an increase in PEEP from 5 to 8 cmH2O to improve the patient's oxygenation." — Ventilator management note
- "Excessive PEEP can lead to barotrauma and decreased cardiac output." — Clinical assessment report
