The American Heart Association is pushing to require students learn CPR in school.
Only 34 states require CPR training as a graduation requirement. The American Heart Association also said that more than 400,000 people have sudden cardiac arrest.
The American Heart Association sells family CPR kits for under $40.
Maryland is one of the states that requires high school students to learn CPR in order to graduate. The law was passed in 2014 and it's named after Breanna Sudano.
Sudano was just 13 years old when she went into sudden cardiac arrest while warming up for a field hockey game at Perry Hall High School. Her coaches and parents performed CPR on her for nearly 10 minutes until an ambulance arrived.
Two years later she testified in Annapolis to get the CPR law passed.
