Abstract:
Ketoacidosis is a medical emergency that requires swift intervention to avert life-threatening sequel. A body-worn sensor () configured to measure the levels of a ketone compound circulating in a physiological fluid of a wearer and capable of generating an alert to the wearer if the level of the circulating ketone compound exceeds a pre-defined level or rate of change is disclosed herein. The sensor () preferably includes at least one of an electrochemical sensor, an optical sensor, a galvanic sensor, a voltammetric sensor, an amperometric sensor, a potentiometric sensor, an impedimetric sensor, a resistive sensor, a capacitive sensor, an ultrasonic sensor, a radio-frequency sensor, or a microwave sensor.
