Which statement about endotracheal intubation time is true in a controlled setting?

• A. 20 seconds are sufficient
• B. 40 seconds or less is a typical target
• C. 60 seconds should be avoided
• D. 90 seconds is recommended

Answer: (B)

In a controlled setting, the goal is to perform endotracheal intubation quickly to minimize the time the patient is without adequate ventilation, reducing the risk of hypoxia. A target of forty seconds or less per attempt is practical and commonly taught because it balances speed with the need to complete the necessary steps: visualize the vocal cords, advance the tube, inflate the cuff, and confirm placement (often with capnography) while maintaining pre-oxygenation. Pushing beyond this window increases the chances of desaturation, especially if airway difficulties or repeated attempts occur. Twenty seconds is typically too optimistic for most clinicians to complete a safe, successful intubation with all steps included. Sixty seconds or more tends to markedly raise the risk of hypoxemia and complications, so it’s generally avoided. Ninety seconds is not recommended because it exceeds the safe apneic window even in controlled settings.
