"Cough CPR" does work in a controlled environment like the cath lab, but I agree it was a hoax. Cough CPR is for the supine patient on the cardiac monitor who is being coached by medical professionals to buy a little time while they attach and charge up the defibrillator. In other words, they see VF on the monitor and coach you to cough. How would you know you were in VF? By the time you figured it out you would be unconscious, especially if you were standing up.
