Hello all,
we had an accident recently in the local community ; from oxygen poisoning. The diver was instructor, recognized as experienced, and had at least one experience buddy with him. They were diving a multi stage deep dive (80msw +).
Looking at this, we're trying with some friend to determine how we should react if a buddy ever comes across such situation. The point is not to go through everything that should be done to avoid it ; but to determine the procedure IF it ever happens.
So far we came up with this :
- Wait for the seizure to pass, keep regulator in mouth if still there.
- Keeping the head toward bottom (to avoid water entry in the mouth), and as soon as the seizure pass, give forcefully bottom mix regulator, ideally on long hose
- Stabilize the situation and follow deco plan. Switch the buddy gas as needed, avoiding switch if possible. Meaning that if a deco stage has enough gas to complete the deco, even if significantly longer that the deco with another higher oxygen stage, do not switch.
The rational is that the seizure is supposed to last about 30 second, during which the buddy cannot breath. When the seizure pass; he will have lost consciousness ; but will be breathing> therefor ; it is critical to make sure he has a regulator in is mouth at this time.
Once this stage is passed, he is not in immediate danger. Although not conscious, it is better for him to finalize deco than to have him bolt to the surface (unless you know a recompression chamber is available near by.)
Does that make sense to you ? what would be your procedure for such case ?
