I have used Medical Wizards (.com) for software called "paramedics toolbox". This, by far, is the most used software I have found. it uhas everything from ACLS to basic CPR. The most impressive secton is the pediatric protocols. It automatically adjusts dosages for the given weight. This has proven to be invaluable during pediatric cardiac arrests. Trust me, you won't be dissappointed. NO, this is not free but what I have learned in life is, you get what you pay for. Good luck.
