!5:2...30:2....could this be next?

[Wildcard]

In case of drowning victim, will not the blood O2 level be almost negligible. What will be the use of chest compressions without providing air. Exhaled air contains about 16% O2 which is good enough to provide Oxygen to the victim during rescue breaths. CCR can be good for cardiac patients but this being a divers forum and considering diving emergency (near drowning) 30:2 seems to be more appropriate. If you have a ambubag on boat or with your rescue kit, one rescuer can take control of respiration of the victim and the second rescuer can keep on providing chest compression till EMS personnel arrive. The chances of survical of the victim will be more.

It is more complex than that. 30:2 is one rescuer CPR or CCR if you chose, for 2 person we don't stop compressions except once every two minutes now. The thinking is that the change in ITP will move some air and since BLS airways in general and M2M in particular are near impossable, this is what they have come up with for now. It will change again when the 2008 standards come out. Recert or take the class for the first time, whatever, it will be explained.
