I have thought long and hard about this answer. It was tough, but I came to a decision. I believe if it is hot outside...the position of the switch should be on. Now...If it is not hot...or dare I say it...cold...it should be in the off position. I hope this answered ur question...God speed.

CPR should be used if someone is unconscious and cannot breathe.
