| This would be a different answer if this was a what should you do question, so i'm gonna shoot from the hip...
I would fin straight down, swapping regs to back gas on the way... am damn sure i'd catch them quickly. Grab them and pull up there head so I can see there face. Check reg, check eyes, check breathing in an instant, whilst pulling them back up to 6 holding the head in a normal position, putting the reg in the mouth whilst purging it on the way.
At 6... Are they breathing? Is the reg in place? If so hold the stop for them...
Not breathing? Take them to the surface and assist onto boat, if i'm last man on board i'd go striaght on O2 and let the boat get moving call the chopper etc... would take things very easy lie down and drink plenty of fluids expecting an evac to a chamber. If there are still others in the water I'd jump back in, go back down and complete my deco plus a bit more expecting a pull at any time. The helicopter isn't always available... |
