Which statement about equalization is not true?

Which statement about equalization is not true?

• A. Preemptively before descent.
• B. Well before feeling any pain or discomfort.
• C. As soon as they feel any pain or discomfort.
• D. Early and often during descent.

Answer: (C)

Equalization is all about keeping the pressure on both sides of the eardrum balanced as you descend, so the membrane isn’t stretched by the increasing ambient pressure. The best approach is to start early and do it often, even before you feel any discomfort. Because the Eustachian tube needs time to open and air to move into the middle ear, waiting until you have pain means you’ve let the pressure differential grow too large. That late cue can leave you with a sharp, preventable ear squeeze or barotrauma. In practice, you should begin gentle equalization before you start descending and continue at regular intervals as you go down. Use small, frequent attempts—swallowing, yawning, gentle jaw movements, or a soft Valsalva if needed and comfortable—to keep the middle ear pressure in step with ambient pressure. If you can’t equalize easily, ascend a bit to give your ears a chance to catch up, and never push through pain. So the statement that you should equalize as soon as you feel any pain or discomfort isn’t true, because waiting for pain reduces your safety margin. The safer approach is preemptive, continuous equalization throughout the descent.
