Sudden Cardiac Arrest & Defibs.

Sudden Cardiac Arrest kills 1,100 Americans each day.
That's almost one person every 1 minute.

Chance of survival drops 7-10% for every minute without defibrillation.
This means civilian response is critical.

Defibrillators are easy* to use, effective, and everywhere.
*Studies have shown untrained 6th graders effectively using defibs in 97 seconds.

Why do some images say Ottawa's Heart?
Heart Spark was originally called Ottawa's Heart, but once we took the app international it really didn't make much sense. Same team and same love, just a new name.
