A device includes a housing, an emitter, a detector, and a processor. The housing has a body contact surface configured for affixation to a tissue site of a body. The emitter is coupled to the housing and has an emission surface and an electrical terminal. The emission surface is configured to emit light proximate the body contact surface in response to a signal applied to the electrical terminal. The detector is coupled to the housing. The detector has a sense surface and an output terminal. The detector is configured to provide an output signal on the output terminal in response to light detected at the sensor surface. The processor is coupled to the electrical terminal and coupled to the output terminal. The processor is configured to implement an algorithm to monitor for an interruption between the body contact surface and the body and configured to generate an interrupt signal corresponding to the monitoring.
