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.
