In one embodiment, a personal flotation device that can be worn by a user includes an inflation system including an inflatable bladder, a gas-generating component configured to generate gas using a chemical reaction and inject the generated gas into the bladder to inflate it, and an actuator configured to activate the gas-generating component; a sensor configured to sense one or more physiological parameters of the user; and an inflation control system configured to receive physiological parameter data from the sensor, to determine whether or not the user is experiencing a medical event that places the user at risk of drowning, and, if the user is experiencing such a medical event, to signal the actuator to activate the gas-generating component so as to provide floatation to the user.
