So this is not exactly a medical device to be used in emergencies, but it is a kickass fitness tracker that can accurately collect data regarding your daily workout which can be extremely important for people with medical complications and conditions. Since the device allows you to record your workout data in the statistical equivalent of stairs, miles and calories burned, the Striiv Fitness Tracker can provide emergency workers and hospital staff with important data about what the kind of physical condition the patient had been before they sustained an injury which can then help then determine the best course of treatment.
