If there is an air leak around the chest-tube dressing, what should you inspect?

• A. Ignore minor leaks for monitoring.
• B. Reapply dressing with more gauze.
• C. Inspect the dressing for leaks and ensure all connections are secure.
• D. Replace the chest tube immediately.

Answer: (C)

When a chest-tube dressing shows an air leak, the priority is to verify the integrity of the dressing and the entire connection so the system remains closed. The best action is to inspect the dressing for leaks and make sure all connections are secure. This ensures an airtight seal around the tube and prevents air from entering or escaping the chest cavity, which could worsen a pneumothorax or cause subcutaneous emphysema. If you find a leak at the dressing, reinforce or replace the dressing to maintain occlusion and check that every connection along the tubing is tight and intact. Ignoring the leak, or trying to fix it by simply adding gauze, isn’t appropriate, and replacing the chest tube is only needed if the tube or system is damaged or malfunctioning.
