What is the recommended maximum duration for a single suction pass during airway suctioning?

• A. Five seconds
• B. Ten seconds
• C. Fifteen seconds
• D. Twenty seconds

Answer: (B)

Limiting suction time protects oxygenation while still clearing the airway. The recommended maximum for a single suction pass is 10 seconds. Prolonged suctioning can quickly drop oxygen saturation, cause hypoxemia, and even provoke bradycardia or airway irritation. To use suction effectively and safely, pre-oxygenate as much as possible, perform passes no longer than 10 seconds, and pause to ventilate and reoxygenate between passes. If needed, repeat after reoxygenation, using shorter passes in children to reduce desaturation risk. Longer passes than 10 seconds greatly increase the risk without reliably improving clearance.
