Third party such as hospitals and fire departments will not download “event data” from the AED that does not belong to them. The event data is only used for employers that want to see how well their rescuers performed or if the medical director (assuming the company has one) wants to look into the cardiac event and rescue further. Usually, the people that looks into the data are medical directors for hospitals, paramedics, and the likes. They would only check the devices that they own.
