Abstract: The present disclosure relates generally to medical devices and, more particularly, to optical medical sensors used for sensing physiological characteristics of a patient. In one embodiment, a system includes a physiological sensor having a photodetector array with a plurality of photodetectors configured to receive light from patient tissue. The physiological sensor also includes a multiplexor configured select and output a signal from the photodetector array. The physiological sensor may also include a signal analyzer configured to determine the signal quality for each of the output signals of the photodetector array and select an output signal, based on the signal quality determination, for the calculation of a physiological parameter of the patient. In another embodiment, a system includes a pulse oximetry sensor having a multiplexed array of photodetectors configured to receive light from patient tissue.

Abstract: Systems and methods are disclosed for producing audible indicators that are based on a subject's measured blood pressure. Audible properties of the indicators are processed to represent blood pressure. For example, the duration or volume of the audible indicators may be varied based on the values of the subject's blood pressure. The audible indicators may further be varied based on the subject's blood pressure's deviation from a normal blood pressure and/or previously calculated blood pressure. For example, the audible indicators may be indicative of changes in the subject's blood pressure over time. The audible indicators representing blood pressure may be synchronized with other audible indicators that represent other physiological parameters of the subject, such as, the subject's heart rate.
