What cuff pressure is commonly recommended for endotracheal tubes?

• A. 60 cmH2O
• B. 10 cmH2O
• C. 25 cmH2O
• D. 45 cmH2O

Answer: (C)

Maintaining the right cuff pressure around the endotracheal tube is about balancing a good seal with protecting the tracheal mucosa. The commonly targeted range is about 20–30 cmH2O, with 25 cmH2O often used as a practical standard. This level seals the airway to prevent leaks and aspiration while keeping blood flow to the tracheal mucosa, reducing the risk of ischemia and injury. Pressures well above this range (like 45–60 cmH2O) increase the chance of mucosal damage and necrosis. A pressure as low as around 10 cmH2O may not adequately seal or protect against aspiration. Therefore, 25 cmH2O sits in the safe, effective middle ground.
