20110245711METHOD AND APPARATUS FOR PERSONALIZED PHYSIOLOGIC PARAMETERS - Methods and apparatus combine patient measurement data with demographic or physiological data of the patient to determine an output that can be used to diagnose and treat the patient. A customized output can be determined based the demographics of the patient, physiological data of the patient, and data of a population of patients. In another aspect, patient measurement data is used to predict an impending cardiac event, such as acute decompensated heart failure. At least one personalized value is determined for the patient, and a patient event prediction output is generated based at least in part on the personalized value and the measurement data. For example, bioimpedance data may be used to establish a baseline impedance specific to the patient, and the patient event prediction output generated based in part on the relationship of ongoing impedance measurements to the baseline impedance. Multivariate prediction models may enhance prediction accuracy.10-06-2011
20110270049Method and Apparatus for Remote Detection and Monitoring of Functional Chronotropic Incompetence - Methods and apparatus to determine the presence of and track functional chronotropic incompetence (hereinafter “CI”) in an in-home setting under conditions of daily living. The functional CI of the patient may be determined with one or more of a profile of measured patient heart rates, a measured maximum patient heart rate, or a peak of the heart rate profile, such as the peak of a heart rate distribution profile. The functional CI of the patient may be determined with the measured heart rate profile, in which the measured heart rate profile may correspond to heart rates substantially less than the maximum heart rate of the patient, such that the heart rate can be safely measured when the patient is remote from a health care provider. The functional CI of the patient may be determined based a peak of the remotely measured heart rate profile, for example a peak corresponding to the mode of the heart rate distribution profile. For example, the relative amounts of the profile of heart rates above the peak and heart rates below the peak can be compared to determine the CI. The peak of the heart rate profile of the remote heart rate data may be used to determine the heart rate reserve and functional CI of the patient. The changes in HR can be measured and correlated to one or more sensor parameters such as activity to determine CI of the patient.11-03-2011

20110295142Detector for identifying physiological artifacts from physiological signals and method - The present invention relates to a physiological monitor and system, particularly to an electroencephalogram (EEG) monitor and system, and a method of detecting the presence and absence of artifacts and possibly removing artifacts from an EEG, other physiological signal or sensor signal without corrupting or compromising the signal. The accurate, real-time detection of the presence or absence of artifacts and removal of artifacts in EEG or other signals allows for increased reliability in the efficacy of those signals. The strategy of rejecting artifact-corrupted EEG can result in unacceptable data loss, and asking subjects to minimize movements in order to minimize artifacts is not always feasible. The present invention allows for increased accuracy in detection and removal of artifacts from physiological signals, substantially in real time, and without loss or corruption of signal or data in order to increase the accuracy of such signals for diagnosis and treatment purposes.12-01-2011
