What does PEEP stand for in the context of mechanical ventilation?

PEEP stands for Positive End-Expiratory Pressure in the context of mechanical ventilation. This terminology is crucial because PEEP is an important parameter used in ventilatory support to prevent the collapse of alveoli at the end of expiration. By maintaining a certain level of pressure in the airways after expiration, PEEP helps keep the alveoli open, improving oxygenation and reducing the work of breathing.

In patients with conditions such as Acute Respiratory Distress Syndrome (ARDS) or other forms of respiratory failure, applying PEEP can enhance lung recruitment and increase functional residual capacity, aiding in the overall ventilation strategy. Understanding the meaning and purpose of PEEP is vital for anyone involved in the management of mechanical ventilation, as it directly relates to the optimization of gas exchange and the overall effectiveness of mechanical support.
