During airway suctioning, what is the maximum duration per attempt?

• A. 2-4 seconds
• B. 20-25 seconds
• C. 30-45 seconds
• D. 10-15 seconds

Answer: (D)

The key idea is that suctioning can rapidly lower oxygen levels and irritate the airway, so each attempt must be short to protect the patient’s oxygenation. For an adult patient, the maximum duration per suction pass is typically 10–15 seconds. This keeps enough time to clear secretions while minimizing the risk of hypoxemia or arrhythmias; if more suctioning is needed, pause to reoxygenate and reassess rather than extending a single pass. Short durations like 2–4 seconds don’t reliably clear secretions, while much longer passes (20–25 or 30–45 seconds) increase the chances of oxygen desaturation and airway injury.
