hiccups

[luckikmc]

does anybody ever get the hiccups while diving.......do you know if they could be due to lung injury

 

[diver 85]

I would not hold my breath to get rid of them..........

Never heard of a case; did it happen to you?

I can see the potential for a lung expansion risk on ascent. I'd want to breath on the half full or less side as I called the dive.

Hiccups are an interesting phenomenon. Most of the time, they are benign, if annoying. They can, however, occur as a result of irritation of the diaphragm or phrenic nerve. This would be unlikely as a symptom of lung overexpansion injury, but I would not say it was impossible.

I heard (years ago) in science class that hiccups were caused by air trapped in the esophagus causing an involuntary attempt to swallow or regurgitate. This "phrenic nerve" thing, if can be done by trapped air sounds like science was right. I would hold breath on exhale during ascent. Not that I know, rather a guess. If I got hiccups under water that didn't quit soon, I would cancel the dive anyway.

Get your dive buddy to scare you.

Plug your ears and take a drink (only fresh water).

Edit: Sorry didn't realize this was in Dr. Deco's forum.
