What is the intrinsic PEEP range typically recommended for patients?

Intrinsic PEEP, or auto-PEEP, refers to the positive end-expiratory pressure that occurs when there is inadequate time for the lungs to fully exhale before the next breath. This can occur in patients with obstructive lung disease, where air trapping is a concern. The typical recommended range for intrinsic PEEP is recognized as being from 3 to 5 cm H2O.

This range allows for adequate ventilation while minimizing the risk of barotrauma and hemodynamic instability that can occur with higher levels of PEEP. Values within this range help to enhance lung compliance and oxygenation without overly compromising cardiovascular function or increasing the work of breathing excessively.

Understanding these parameters is crucial for healthcare providers, as they guide the management of patients who may be experiencing respiratory distress due to conditions such as asthma or COPD, where intrinsic PEEP can play a significant role in their respiratory mechanics.
