In mechanical ventilation, what does PEEP stand for?

PEEP stands for Positive End Expiratory Pressure, which is a critical component in mechanical ventilation. It refers to the pressure that remains in the airways at the end of expiration. By maintaining a certain level of pressure in the lungs, PEEP helps keep the alveoli open, improving gas exchange and preventing collapse of the lung units. This is especially beneficial in patients with conditions like Acute Respiratory Distress Syndrome (ARDS) or other forms of respiratory failure, as it enhances oxygenation and reduces the work of breathing. Utilizing PEEP effectively can lead to improved oxygenation and overall better outcomes for patients under mechanical ventilation.
