Resoundingly Human: Drones and defibrillators: Saving minutes to save lives

Cardiovascular disease, a term for a number of disorders of the heart and blood vessels, is a serious and steadily growing threat to global health, causing even more deaths every year than cancer. In the U.S. alone, nearly 660,000 people, or 1 in 4, die of heart disease annually.

In particular, cardiovascular disease can lead to cardiac arrest, a serious condition in which the heart suddenly stops beating. One of the most effective methods of treatment for cardiac arrest is an automated external defibrillator, which can not only correct an episode of arrhythmia, or irregular heartbeat, but can restore the heart's beating if it suddenly stops.

As with any medical emergency, time plays a critical factor and this is particularly true when someone is experiencing cardia arrest. Even a minute delay in defibrillation can leading to a 10% decrease in survival.

My guest today, Tim Chan with the University of Toronto, is conducting incredible research exploring how drone technology can minimize delays in defibrillation for individuals in crisis, potentially even faster than traditional EMS can respond.
