    摘要: Embodiments of the invention are related to methods and devices for respiratory or cardiac disease detection, monitoring, and/or management. In an embodiment, the invention includes a method of calculating a pulmonary function parameter of a subject. The method can include obtaining a first signal indicative of lung volume change during breathing from a first sensor, obtaining a second signal indicative of distending pressure from a second sensor, and calculating the pulmonary function parameter based on the first signal and the second signal. In an embodiment, the invention includes a method of monitoring pulmonary or cardiac disease status. In an embodiment, the invention includes an implantable medical device. The implantable medical device can include a first sensor configured to produce a first signal indicative of lung volume change during breathing, a second sensor configured to produce a second signal indicative of intrapleural pressure, and a processor configured to calculate lung compliance or pulmonary resistance based on the first signal and the second signal. Other aspects and embodiments are provided herein.

    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.

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.
