    摘要： Devices and methods for detecting disordered breathing involve determining that the patient is asleep and sensing one or more signals associated with disordered breathing indicative of sleep-disordered breathing while the patient is asleep. Sleep-disordered breathing is detected using the sensed signals associated with disordered breathing. The sensed signals associated with disordered breathing may also be used to acquire a respiration pattern of one or more respiration cycles. Characteristics of the respiration pattern are determined. The respiration pattern is classified as a disordered breathing episode based on the characteristics of the respiration pattern. One or more processes involved in the detection of disordered breathing are performed using an implantable device.

    摘要： This patent document discusses, among other things, systems, devices, and methods for enhancing detection of pulmonary edema using, in addition to thoracic impedance, one or a combination of: physiologic information about a subject, at least one statistical parameter, a user-programmable detection level, at least one parameter associated with a previous pulmonary edema event, and patient symptom information about the subject. In one example, a (base) thoracic impedance threshold is modified to an adjusted thoracic impedance threshold. The adjusted thoracic impedance threshold provides an increased sensitivity of pulmonary edema detection as compared to the base thoracic impedance threshold. In another example, an alert is provided to a subject, a caregiver, or other user based on a pulmonary edema indication determined by the present systems, devices, and methods. In a further example, a therapy (provided to the subject) is adjusted or initiated in response to the pulmonary edema indication.

    摘要： A system includes an implantable medical device that includes a trans-thoracic impedance measurement circuit providing a trans-thoracic impedance signal of a subject. A controller is coupled to the trans-thoracic impedance circuit. The controller extracts a respiration signal from the trans-thoracic impedance signal, measures a breathing volume of the subject using the amplitude of the respiration signal and a breathing volume calibration factor, computes an adjusted breathing volume calibration factor using a reference baseline value of the trans-thoracic impedance and a measured baseline value of the trans-thoracic impedance, and computes a calibrated breathing volume using the adjusted breathing volume calibration factor.

    摘要： This patent document discusses, among other things, systems, devices, and methods for predicting an occurrence of impending thoracic fluid accumulation and in one example, invoking a responsive therapy, such as to prevent or minimize the consequences of the impending thoracic fluid accumulation. One example of the present systems, devices, and methods senses or receives at least one parameter that is statistically associated with impending thoracic fluid accumulation from a subject. Using such parameter(s), a probability of impending thoracic fluid accumulation is estimated. A list of parameters determines which values are recurrently sensed or received at various desired time intervals. Another example of the present systems, devices, and methods weights the sensed or received parameter value(s) to compute the probability estimate of impending thoracic fluid accumulation. A responsive preventive thoracic fluid accumulation therapy or other therapy is selected and activated using the probability estimate of impending thoracic fluid accumulation.

    摘要： This document describes, among other things, systems, devices, and methods that use frequency domain analysis of a thoracic signal. One example uses frequency domain analysis for discriminating between different pulmonary physiological states. Examples of breathing states include normal breathing, periodic breathing, Cheyne-Stokes breathing, obstructed respiration, restrictive respiration, and pulmonary edema. The frequency domain analysis may also be used for performing heart rate variability (HRV) diagnostics. In one example, a frequency domain adaptive filter implements a variable cutoff frequency for separating heart contraction spectral content and other spectral content from lower frequency respiration spectral content and other lower frequency spectral content.

    摘要： This document discusses, among other things, a cardiac function management device or other implantable medical device that includes a test mode and a diagnostic mode. During a test mode, the device cycles through various electrode configurations for collecting thoracic impedance data. At least one figure of merit is calculated from the impedance data for each such electrode configuration. In one example, only non-arrhythmic beats are used for computing the figure of merit. A particular electrode configuration is automatically selected using the figure of merit. During a diagnostic mode, the device collects impedance data using the selected electrode configuration. In one example, the figure of merit includes a ratio of a cardiac stroke amplitude and a respiration amplitude. Other examples of the figure of merit are also described.
