Abstract: A medical system for sensing a physiological state requiring defibrillation in a patient. The system comprising: a low power sensor, a physiological parameter measuring device, and a processor. The low power sensor generating a baseline signal relating to a physiological status of said patient. The physiological parameter measuring device comprising at least one higher power sensor configured to output at least one physiological parameter signal indicative of at least one physiological parameter of said patient. The processor assessing the baseline signal and determining if the physiological status is outside predetermined threshold boundaries.

Abstract: Personal health monitoring devices and methods are disclosed. A health monitoring device includes a sensor unit including a source and receiver of optical energy, a housing configured to receive and house the sensor unit, and a coupling mechanism configured to couple the housing to a band to be worn at least partially about one of a wrist or a lower forearm of a wearer of the band. The coupling mechanism is further configured to position the housing pointing the sensor unit inward to the wrist or lower forearm of the wearer with an inward radial force on the sensor unit based on tension in the band. The health monitoring device also includes a data storage device and a processor configured to receive, from the sensor unit, data about received optical energy, and to produce photoplethysmogram data using the received data, and to store data to the data storage device.
