Question: 1 / 400

What should be done if a diver experiences trouble equalizing during descent?

Descend faster to minimize pressure

Ascend slightly to reduce pressure and try to equalize again

When a diver experiences trouble equalizing during descent, ascending slightly to reduce the pressure is the appropriate action. This allows the diver to address the discomfort because the pressure on the ears or sinuses can be more manageable at a shallower depth. By ascending just a few feet, the diver can attempt to equalize again using techniques like pinching the nose and gently blowing or swallowing.

This strategy also ensures that the diver is taking a proactive approach to prevent potential injury or complications that can arise from equalization difficulties, such as barotrauma. It is crucial to maintain communication with a dive partner or guide, but signaling for assistance is secondary to controlling one's own situation first, making it essential to prioritize one’s safety through equalization techniques when encountering issues.
