Observed blackouts

[cebaztian]

I am writing an article on Laryngospasm.

I need your help.

I need to hear about observed blackouts.

I will post the results here - it might be interesting:

1. Name of victim (first name is ok)
2. Year and place
3. Discipline
4. Depth of BO
5. release of air?
6. Time until breathing , from estimated BO, and from surfacing.
7. Type of handling of victim.
8. Water in lungs (one drop, three drops, a mouthful?).
9. Any squeeze involved

From what I have seen, 3 minutes seems to be the average duration of the spasm. Prior to that, artificial respiration can be difficult or impossible. Tom's spasm in 2003 was 3 minutes after video review.

Cebaztion,

Here is interesting account of my Laryngospasm, I have not heard any others like it:

I was training dynamic at my local 25m pool. I did 3x25m (75m) with a static hold at the end, maybe 15 or 20 seconds. I exhaled the air OK, and on the inhale had 2 or 3 "gulpy" interruptions that I recognized as involuntary contraction of my larnyx. After that breathing was normal. I had recently done a PFI course so had seen videos of this type of thing so am sure that is what it was. I am also sure if I had not had this training I would not have recognized it at all and certainly not as a sign of hypoxia. I also clearly remember this incident unlike others I have had with no memory where people explained what had happened to me. I think part of why this might have happened is that there is a very very strong urge to breathe after you come up from the water and so I would have been holding my larnyx "harder" to keep from breathing and this may have contributed to the larngyospasm while I was not hypoxic enough to lose consciosness.
