HBOT cautions include avoidance during which acute symptom?

• A. Rash
• B. Cold or fever
• C. Nausea
• D. Headache

Answer: (B)

HBOT relies on safe pressure changes, so the body must be able to equalize pressure in the ears and sinuses during compression and decompression. A cold or fever often causes nasal congestion and sinus edema, which impairs Eustachian tube function. When you can’t equalize effectively, there’s a real risk of ear and sinus barotrauma and significant discomfort during the session. Because of that safety concern, an acute cold or fever is a reason to postpone HBOT until symptoms have resolved and nasal/sinus passages are functioning normally. Other symptoms like rash, nausea, or headaches can be assessed for alternative causes and managed, but the acute congestion from a cold or fever most directly compromises safe chamber equalization.
