What is the normal PEEP value range commonly used?

• A. 0-2 mmHg
• B. 5-10 mmHg
• C. 15-20 mmHg
• D. 25-30 mmHg

Answer: (B)

PEEP, or positive end-expiratory pressure, is the pressure kept in the lungs at the end of exhalation to keep alveoli from collapsing and to improve oxygenation. In adults receiving ventilation, a common starting point is about 5 cm H2O, with adjustments often in the 8–10 cm H2O range if oxygenation needs rise. Too little PEEP risks alveolar collapse and poor oxygenation; too much PEEP can overdistend the lungs and reduce venous return, causing hemodynamic issues. So, the standard, commonly used range sits in the middle—around 5–10 cm H2O. The other ranges are either effectively no PEEP or excessively high PEEP.
