Background: What’s an AED? AED is an automated external defibrillator Can shock and restart the heart if it stops beating normally Provide life-saving audible CPR instructions
Background: Why do we need AEDs? Every year, 300,000 Americans suffer from out-of- hospital cardiac arrest. One study estimates that an AED is used in 8% of out-of-hospital cardiac arrests. In Philadelphia, an AED is used approximately 1-2% of out-of-hospital cardiac arrests. Rapid defibrillation in some cases can significantly improve chances of survival from <1% to >50%. The chance of survival decreases 7-10% each minute in cardiac arrest.
How can we address these issues? Project goals Raise AED awareness Find out where AEDs are and build a map for the general public and 911 dispatchers! Map for 911 Launch the Validate dispatchersCanvassing MyHeartMap Contest and Challenge Entries smartphone app
Methodology: Canvassing 2 teams of 2 summer students collected information in Philadelphia County about AEDs Door-to-door asking if buildings have installed AEDs Developed a survey Type of building Time spent in building Number of people contacted AED location Has the AED ever been used? Is the AED readily visible to visitors?
Where we canvassed Used block groups (U.S. Census) Canvassed 12 block groups in Philadelphia Selected block groups with the most jobs because of more public locations
Preliminary ResultsProcess of Canvassing No patterns regarding which buildings have them and which buildings don’t. Many large buildings do not have them, yet some small retail businesses do have them. It often requires contacting more than one person to find out whether or not a building has an AED. Searching for AEDs is time consuming Ranged from 1 minute to 1 hour for a building
