What is PEEP?

PEEP stands for Positive Expiratory End Pressure and refers to the measurement of pressure within the alvioli at the end of the expiratory cycle. By increasing the PEEP, the alvioli are forced to remain open, allowing greater difusion of oxygen and Co2 at the point of gas exchange (the alvioli).

PEEP is often used during mechanical ventilation to ensure that the patient is getting the greatest amount of gas exchange in patients with severe respiratory disorders, such as ARDS, Pneumnia, and any other common cause of a V/Q inequality (a problem with ventilation and perfusion).
