So basically, I should do 6 compressions, 3 breaths, and repeat that like 8 times?  Then deliver a shock and a shot of Supreranal.  Got it!  EDIT:  WOW, I fail.  The first block, I didn't deliver any medicine since the doctor wasn't ready.  The 2nd-5th blocks I did 6 compressions, 3 breaths (8 times until HDM and Beatmung said 8), then 1 defib.  After that, I did the same compressions and stuff, but instead of Atropine, I administered Coradex!  The guy died.
