Abstract:
A probabilistic digital signal processor using data from multiple instruments is described. In one example, a digital signal processor is integrated into a biomedical device. The processor is configured to: use a dynamic state-space model configured with a physiological model of a body system to provide a prior probability distribution function; receive sensor data input from at least two data sources; and iteratively use a probabilistic updater to integrate the sensor data as a fused data set and generate a posterior probability distribution function using all of: (1) the fused data set; (2) an application of Bayesian probability; and (3) the prior probability distribution function. The processor further generates an output of a biomedical state using the posterior probability function.

Claim (Index 1):
An apparatus for estimation of a biomedical state of a body having a cardiovascular system, comprising:\n a biomedical device comprising: a pulse oximeter; an electrocardiogram device; an output display screen; and a digital signal processor integrated into said biomedical device, said biomedical device configured to:\n use a dynamic state-space model, implemented with a probability distribution function representative of a physiological description of the cardiovascular system, to provide a prior probability distribution function; \n receive sensor data input from at least two data sources, wherein the sensor data from said at least two data sources comprises:\n first output from said pulse oximeter, said pulse oximeter configured to monitor a first sub-system of the cardiovascular system, said pulse oximeter used to determine a first parameter comprising a first unit of measure; and \n second output from said electrocardiogram device, said electrocardiogram device configured to monitor a second sub-system of the cardiovascular system, said electrocardiogram device used to determine a second parameter comprising a second unit of measure, said first unit of measure distinct from said second unit of measure; \n \n iteratively use a probabilistic updater to integrate the sensor data as a fused data set and generate a posterior probability distribution function using all of:\n (1) the fused data set; \n (2) an application of Bayesian probability; and \n (3) said prior probability distribution function; and \n \n generate an output of a biomedical state using said posterior probability function, \n wherein said output of a biomedical state comprises an indirect parameter having a third unit of measure distinct from both said first unit of measure and said second unit of measure, said indirect parameter calculated using both said first output and said second output, \n wherein said indirect parameter comprises at least one of:\n a stroke volume of a heart; \n a filling rate of the heart; and \n a measure of contractility of the heart; and \n \n at least one of said pulse oximeter and said electrocardiogram device comprise an element of a medical rack system.
