> In a four-month pilot study testing the EMADE program, the service got 14 heart attack alerts that would be eligible for drones. Drones took off in 12 of those cases, and 11 successfully delivered the defibrillators. Seven of those defibrillators were delivered before the ambulance arrived.

So if this is the first patient saved does that mean all 11 people that were delivered defibrillators in the pilot study died?

Maybe, as it says, "The survival rate is about 10%" even though large numbers of people experience cardiac arrest in a clinical setting where they had defibrillators for years. Lots of Cardiac Arrest incidents aren't survivable, if your heart actually stopped they can't do anything about that. But without measuring (the first step the AED takes) you can't tell whether the heart is stopped or merely stuck twitching and not pumping blood, in the latter case the defibrillator may fix that, hence the name.

*Most* attempts fail even in the hospital.
