  • Patent number: 11406272
    Abstract: A method of determining a blood pressure of a patient includes determining a plurality of pressure pulses, wherein each pressure pulse of the plurality of pressure pulses comprises a profile having a maximum profile height. The method also includes determining a pulse score associated with the plurality of pressure pulses, wherein the pulse score is determined based on the profiles of the pressure pulses and the maximum profile heights. The method further includes determining that the pulse score is above a pulse score threshold, and generating, in response to determining that the pulse score is above the pulse score threshold, a pulse curve based on the maximum profile heights. The method also includes determining the blood pressure of the patient without completely occluding a blood vessel of the patient, wherein the blood pressure is determined based on a plurality of values corresponding to respective points on the pulse curve.

  • Patent number: 11202578
    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.

  • Patent number: 11039795
    Abstract: A method of estimating oxygen saturation includes illuminating a target site with light of three different wavelengths, for example green, red and infrared, and detecting light returned from the site at each of the wavelengths. The method distinguishes between cardiac pulsatility and nonpulsatility based on a parameter of the return light of the shortest wavelength. The method formulates an estimate of oxygen saturation as a function of a parameter of the light of the two longer wavelengths taken at both a period of pulsatility and at a period of nonpulsatility. An oximeter adapted to carry out the method is also disclosed. Aspects of the method and oximeter may be used to estimate other physiological parameters.
