use of EDD kit

  1. About a week ago , as a student required to re-cert on cpr, i made an observation, that i believe might be of intrest. During application of the EDD kit no where does this insrtuction, offer wet environment application introduced. This was of concern to me. Do you think that a foam rubber like bed roll could solve this issue, for instance, at pool side, or in an industrial area where a accident occur's, and moving the patient out of the area is impossible. The question is; Could an insulator like this be of benifit in this regard?
