Dive #75 : Rescue Diver Session #3, Mactan Island, Philippines

Rescue diver sessions continuing with more rescue scenarios and missing diver search patterns. First however for of mentioning that scored full 50/50 points from the theory part, guess I really had time to study my book due to a couple of weeks delay of the course. I picked the book two weeks before, fell with a strong flu and had to postpone the practical sessions. Seems like the studying paid off!

We started with another missing diver search patterns, practicing the expanding square, U-pattern and the expanding circle with a line. Then to the most useful stuff, a diver panicking in 20 meters depth, surging to the surface full speed holding breath. So what ya do, let the sad bastard go an experience the free thrills of lung expansion combined with the joy of decompresson sickness? I mean those nitrogen bubbles in your bloodflow cant be that bad right! Oh well for the sake of the course the poor fellow had to be saved, so grabbing and controlling the dude underwater, providing you air supply and taking him calmly to the surface with safety/deco stops. This was great stuff, we actually should have more this which I think is closer to a situation that might happen (and did happen in Belize) in the real world. However we also concentrated quite a bit to rescuing unconscious diver from the bottom, something I dont see THAT common. Anyway, a crapload of time was spent to on-the-surface rescue breaths and ventilations, oxygen masks usage and towing the victim onto land. Pretty good, and tirening, stuff. The burning jellyfish patrolling the area didn't make it much easier, neither the zillions of locals who were spending their sunday afternoon playing at the beach. Once when we surfaced, a waterjet roamed about 5 meters from us...

Ended the session with some free diving excercises, to approximately 3-4 meters and swimming around without equipment.
