In the context of lung function, "PEEP" stands for Positive End-Expiratory Pressure. This term refers to a mode of mechanical ventilation in which a pressure is maintained in the airways at the end of expiration. This pressure helps to keep the alveoli open, prevents their collapse, and improves oxygenation by increasing functional residual capacity (FRC). Maintaining a certain level of end-expiratory pressure is crucial in managing patients with respiratory distress, acute respiratory syndrome, or those requiring mechanical ventilation.

The other interpretations of the acronym do not accurately reflect established concepts within pulmonary function. While Positive Expiratory Pressure does exist, it specifically refers to a different process often used in airway clearance techniques. Pneumothorax End-Expiratory Pressure and Pneumonia End-Expiratory Pressure are not recognized terms in the field and hence are not applicable in this context. Therefore, Positive End-Expiratory Pressure is the correct and recognized term that pertains to the management and support of respiratory function.
