Quick takeaways
- Understanding the determinants of mean airway pressure, including the roles of PEEP and FiO2, is critical for patient oxygenation in ARDS.
- Lung Volume Recruitment Maneuvers are beneficial for improving oxygenation by recruiting collapsed lung units before increasing PEEP settings.

Understanding Oxygenation in ARDS Patients
Oxygenation in patients with Acute Respiratory Distress Syndrome (ARDS) relies heavily on the mean airway pressure (MAP), which is influenced by factors such as Positive End Expiratory Pressure (PEEP) and fractional inspired oxygen (FiO2). During mechanical ventilation, clinicians aim to manipulate these variables to maintain adequate oxygenation levels. By increasing PEEP, the potential for recruiting derecruited lung units improves, thereby enhancing functional residual capacity (FRC). Understanding the relationship between MAP and these factors is crucial, as it becomes evident that they collectively play a significant role in patient outcomes.
