What is the physiologic PEEP indicated as?

Physiologic PEEP, or Positive End-Expiratory Pressure, is typically indicated as 5 cm H2O in clinical settings. This measurement is important because it represents the pressure remaining in the airways at the end of expiration, which helps to keep the alveoli open, improving gas exchange and preventing alveolar collapse.

In a healthy individual, a physiologic PEEP of around 5 cm H2O is considered normal, as it assists with optimal lung mechanics and oxygenation. It is also used as a reference point in various clinical scenarios to differentiate between health and disease states and to make decisions regarding mechanical ventilation strategies.

Understanding the concept of PEEP in relation to lung physiology is critical in both acute and chronic care settings, especially in the management of patients with respiratory distress or failure.
