Hello all,
Yesterday I did a recreational diving session on FRC, which is not new to me since I've been diving exclusively on FRC for more than a year.
Depth varied from 15m to 21m with dive times not exceding 1'30 - all parameters well within my capacities.
After one dive I had an irresistible need to cough and when I spat my saliva was brownish/light orange. I tried to go down again but it was almost impossible because the cough was coming back at about 5m (and you don't want to cough underwater...)
I had no pain in my chest and lungs, and the brownish color in my saliva disappeared in a short time after I stopped diving (about 1 hour).
Is this a case of trachea squeeze ? I know that I was not as relaxed as usual and this was causing equalization to require lots of focus. If this is a tracheal squeeze, are there any ways to overcome this ?
Thanks,
Fabrice
