Publication number: 20140316292Abstract: A peripheral arterial flow obstruction detection system for providing a predictive diagnosis correlating to the diagnosis peripheral arterial disease. The system includes a host computer and a sensor used to detect and measure a physiological signal from a subject's finger or toe, such as the measurement of a signal using photoplethysmography using a PPG sensor. Sensor data is processed and filtered before being used to calculate a number of time-domain and frequency-domain calculations corresponding to the signal waveform. The calculations are used in a predictive model using a multi-faceted algorithm to provide a predictive diagnosis that is displayed on an indicator such as a monitor.Type: ApplicationFiled: April 19, 2013Publication date: October 23, 2014Applicant: Semler Scientific, Inc.Inventors: Bob McRae, Paul Mannheimer, James McNames, Doug Murphy-Chutorian

Patent number: 8529458Abstract: Methods and apparatus for determining a cardiac parameter from cardiovascular pressure signals including arterial blood pressure (ABP) and the photoplethysmographic signal to quantify the degree of amplitude modulation due to respiration and predict fluid responsiveness are disclosed. Disclosed embodiments include a method for assessing fluid responsiveness implemented in a digital computer with one or more processors comprising: (a) measuring a cardiovascular signal, and (b) computing a dynamic index predictive of fluid responsiveness from said cardiovascular signal using a nonlinear state space estimator. According to one particular embodiment, and without limitation, the nonlinear state space estimator is based on a model for cardiovascular signals such as arterial blood pressure or plethysmogram signals, and employs a marginalized particle filter to estimate a dynamic index predictive of fluid responsiveness that is substantially equivalent to a variation in pulse pressure of said cardiovascular signal.Type: GrantFiled: September 27, 2010Date of Patent: September 10, 2013Assignees: State of Oregon by and Through the State Board of Higher Education on Behalf of Portland State University, APDM, Inc.Inventors: Sunghan Kim, Pedro Mateo Riobo Aboy, James McNames

Patent number: 8057398Abstract: Disclosed embodiments of the invention include a method, system, and apparatus to monitor cardiovascular signals such as arterial blood pressure (ABP), pulse oximetry (POX), and intracranial pressure (ICP). The system can be used to calculate and monitor useful clinical information such as heart rate, respiratory rate, pulse pressure variation (PPV), harmonic phases, pulse morphology, and for artifact removal. The method uses a statistical state-space model of cardiovascular signals and a generalized Kalman filter (EKF) to simultaneously estimate and track the cardiovascular parameters of interest such as the cardiac fundamental frequency and higher harmonics, respiratory fundamental frequency and higher harmonics, cardiac component harmonic amplitudes and phases, respiratory component harmonic amplitudes and phases, and PPV.Type: GrantFiled: August 29, 2008Date of Patent: November 15, 2011Assignees: APDM, Inc., State of Oregon by and through the State Board of Higher Education on Behalf of Portland State UniversityInventors: James McNames, Pedro Mateo Riobo Aboy
