Certified Hyperbaric Technologist Practice Test 2026 – Comprehensive Exam Prep

Question: 1 / 625

A patient who aggressively uses the Valsalva technique risks causing which condition?

Tympanic membrane perforation

Round window rupture

Using the Valsalva maneuver, which involves forcefully exhaling against a closed airway, can create significant pressure changes within the middle ear. One major risk of this technique is the potential for a round window rupture. The round window is a membrane-covered opening that allows sound waves to enter the cochlea. Excessive pressure can lead to damage or rupture of this membrane, affecting hearing and balance.

This condition is particularly important for hyperbaric technologists to understand, as patients undergoing hyperbaric treatment may encounter pressure changes that can inadvertently lead to such complications if they attempt to equalize pressure using the Valsalva technique without proper guidance. Proper techniques for equalization should be emphasized during hyperbaric therapy to prevent such incidents.
