Straddling the patient is how I learned to do CPR.Actually a lot more informative than I thought it would be. I think the mock-coitus position might be a little hard to sustain (outside the bounds of sex) though.
Yeah! CPR is hard enough to keep up with for long.Ditto what bish said. You need to be able to move away quickly if needed. Also, I doubt you mime sex if you straddle. Too much energy expenditure.
