Comments
The dangers of NOT bringing a diver to the surface would far out weigh actually bringing him there. Normal rec. divers should not be having a problem with O2 tox. because for O2 to become toxic would take depths far below 130 ft., what they should be diving at. Even if using Nitrox, the chances of O2 tox. would be smaller than the other problems the diver is most likely facing. If you for a fact KNOW it is O2 tox., then you should treat it accordingly IF possible. But in most cases getting the diver to the surface is priority number one. And about the comment on not being able to surface yourself safely, well if you're following no dec. diving, then you should ALWAYS be able to ascend to the surface at ANY point in your dive. So this should not be a problem.
I am diver certified and all of the correct answers in this test were accurate if you disagree with something there is an explanation in the PADI Open water diver manual
No. 19 - If a diver is unresponsive it could be due to a number of factors. E.G. O2 Toxicity. Bringing him to the surface would exacerbate the problem. One should give him another source of breathing a weaker mix, stabilise the diver (let any convulsion pass) then take him to the surface.
Please edit that question.
on number 18 you should include the depth in feet as well as meters
I disagree with number 19 - "bring the diver immediately to the surface." Depending on the situation, you may not be able to safely ascend immediately to the surface yourself. I was taught early on that we don't want to create a second victim - your own safety has to come first.
Just food for thought
