摘要： A method and apparatus for providing congestive heart failure therapy status. An electronic device, preferably a cardiac rhythm management device, capable of measuring transthoracic impedance and for sensing a level of physical activity is implanted in a patient. The transthoracic impedance signal is processed to obtain an estimate of the subject's minute ventilation, respiratory rate, tidal volume, inspiratory rate and expiratory rate. From accelerometer measured activity, an estimate is obtained of oxygen uptake, carbon dioxide production and work rate. Ratios of tidal volume to respiratory rate, tidal volume to inspiratory time, tidal volume to expiratory time, heart rate to minute ventilation, respiratory rate to minute ventilation, tidal volume to minute ventilation, minute ventilation to oxygen uptake, minute ventilation to carbon dioxide production, minute ventilation to work rate, heart rate to work rate, oxygen uptake to heart rate and other ratios are meaningful status indicators for assessing the efficacy of particular therapy regimens to CHF patients.

摘要： Changes in patient status are assessed based at least in part on respiration parameters. A user can make selections regarding alert criteria options to be used in assessing patient status. Respiration is implantably sensed and respiration data is stored by an implantable device. A respiration parameter, such as respiration rate, is measured from the respiration data. The change in patient status is assessed by comparing the respiration parameter to the configured alert criteria. If the comparison of the respiration parameter and the configured alert criteria indicates a significant change in patient status, an alert signal is generated.

摘要： A system receives signals indicative of cardiopulmonary conditions sensed by a plurality of sensors and provides for monitoring and automated differential diagnosis of the cardiopulmonary conditions based on the signals. Cardiogenic pulmonary edema is detected based on one or more signals sensed by implantable sensors. If the cardiogenic pulmonary edema is not detected, obstructive pulmonary disease and restrictive pulmonary disease are each detected based on a forced vital capacity (FVC) parameter and a forced expiratory volume (FEV) parameter measured from a respiratory signal sensed by an implantable or non-implantable sensor. In one embodiment, an implantable medical device senses signals indicative of the cardiopulmonary conditions, and an external system detects the cardiopulmonary conditions based on these signals by executing an automatic detection algorithm.
