Abstract: The invention provides a body-worn patch sensor for simultaneously measuring a blood pressure (BP), pulse oximetry (SpO2), and other vital signs and hemodynamic parameters from a patient. The patch sensor features a sensing portion having a flexible housing that is worn entirely on the patient's chest and encloses a battery, wireless transmitter, and all the sensor's sensing and electronic components. It measures electrocardiogram (ECG), impedance plethysmogram (IPG), photoplethysmogram (PPG), and phonocardiogram (PCG) waveforms, and collectively processes these to determine the vital signs and hemodynamic parameters. The sensor that measures PPG waveforms also includes a heating element to increase perfusion of tissue on the chest.

Abstract: A method for estimating blood pressure of a care recipient includes establishing a pre-maneuver reference value of blood pressure and a companion nonreference value of blood pressure, subjecting the care recipient to a maneuver, establishing a post-maneuver reference value of blood pressure and a companion post-manuever nonreference value of blood pressure, establishing an operational post-maneuver nonreference value of blood pressure, and adjusting the operational value as a function of the pre-maneuver and post-maneuver values. An associated apparatus includes a sensor, a processor and a memory which contains instructions. The instructions, when executed, cause the processor to estimate blood pressure as a function of a pre-maneuver reference value of blood pressure, a companion pre-maneuver nonreference value of blood pressure, a post-maneuver reference value of blood pressure, a companion post-manuever nonreference value of blood pressure, and an operational value of blood pressure based on information sensed by the sensor.
