What is the typical range for Positive End Expiratory Pressure (PEEP) in cm H2O?

The typical range for Positive End Expiratory Pressure (PEEP) is primarily between 5 and 15 cm H2O, as higher values are often encountered in clinical settings for specific patient needs, which is why an answer indicating 0-20 cm H2O is considered within an appropriate range for understanding PEEP application.

PEEP is used in mechanical ventilation to maintain alveolar patency and improve oxygenation by preventing the collapse of alveoli at the end of expiration. The PEEP setting helps to recruit collapsed lungs and enhance gas exchange, particularly in conditions such as Acute Respiratory Distress Syndrome (ARDS) or other forms of pulmonary failure.

In clinical practice, values lower than 5 cm H2O may not be sufficient to achieve these benefits, while values exceeding 15 cm H2O require careful consideration, as they can lead to hemodynamic compromise due to decreased venous return and reduced cardiac output. Understanding the implications of PEEP levels is crucial for managing patients with respiratory distress effectively, ensuring an optimal balance between ventilation and circulation.

While the provided response may suggest a broader understanding of PEEP application, it's important to remember the clinical context in which PEEP settings are typically utilized for effective patient management.
