What action should be taken if middle ear squeeze is suspected during a dive?

• A. Cease diving
• B. Continue descent
• C. Increase depth
• D. Ignore

Answer: (A)

Ear barotrauma from rapid pressure change during descent must be managed by stopping the dive to prevent further worsening of the middle-ear pressure. When middle ear squeeze is suspected, ceasing the descent allows the diver to avoid increasing the pressure on the tympanic membrane, which could lead to rupture or more serious injury. If possible, attempt gentle equalization and, once safe, begin a controlled ascent to relieve the pressure. Ignoring the symptoms or continuing to dive would raise the risk of damage, while increasing depth would worsen the squeeze. Seek medical evaluation if symptoms persist.
