International Classification:

A61B 5/0402

US Classification:

600513

Abstract:

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.

Abstract:

A cluster of computer system nodes connected by a storage area network transmit messages using a messaging protocol having multiple layers. The storage area network supports computer system nodes running different operating systems on different endian processors. A heartbeat signal is transmitted in a common wire format over the lowest level of the messaging protocol; however other messages between the nodes may be transmitted in a format different from the common wire format. The node receiving a message is responsible for converting the format as necessary in a layer just above the layer of the messaging protocol handling heartbeat signals. However, conversion may be performed by the sending node if the sending node knows the format used by the receiving node.

Abstract:

This document discusses, among other things, methods of monitoring physiological responses to steady state activity. In an example, a physical activity signal is detected from a human or animal subject using an implantable medical device. A different, other physiological signal is also detected from the subject using the implantable medical device. The physical activity signal is processed to define first and second time periods associated with first and second steady-state physical activity levels of the subject. A first indicator is obtained by combining data from the other physiological signal obtained during the first time period. A second indicator is obtained by combining data from the other physiological signal obtained during the second time period. The first and second indicators are used provide a diagnostic indicator.

US Classification:

600301

Abstract:

An implantable or other ambulatory medical apparatus comprises a posture sensing circuit, a physiologic sensing circuit that senses a time varying physiologic signal, and a processor circuit. The processor circuit includes a posture calculation circuit and a measurement circuit. The posture calculation circuit determines a posture of the subject using posture data obtained using the posture signal and determines when the posture of the subject is steady state. The measurement circuit derives a physiologic measurement using physiologic data extracted from the physiologic signal during at least one time period when posture is determined to be steady state and provides the physiologic measurement to at least one of a user and a process in association with the determined steady state posture.

US Classification:

607 18, 607 42

Abstract:

An inspiratory muscle stimulation system uses an implantable medical device to deliver stimulation to control diaphragmatic contractions for slower and deeper breathing, thereby conditioning and strengthening inspiratory muscles. In various embodiments, respiratory and/or cardiac performance are monitored for controlling parameters of the stimulation.

International Classification:

A61B 5/0205

US Classification:

600301

Abstract:

Patient posture information can be received, such as to indicate a change in patient posture by at least a threshold amount. A transient response signal indicative of a change in a physiological parameter can be received at multiple instances near a change in patient posture. Waveform morphology features can be extracted from a transient response signal and used to provide an indication of a cardiac status, such as a heart failure status.

International Classification:

A61N 1/36

US Classification:

607 42

Abstract:

An apparatus comprises a physiologic sensing circuit and a control circuit. The physiologic sensing circuit is configured to sense an electrical respiration signal representative of respiration of a subject. The control circuit includes a respiration monitor circuit and a therapy circuit. The respiration monitor circuit is configured to extract a respiration parameter from the respiration signal and detect that a value of the respiration parameter is outside of a target value range for the respiration parameter. The therapy circuit is configured to deliver neural stimulation to the carotid sinus of the subject to stimulate respiration and to adjust respiration to maintain the value of the respiration parameter within the target value range.

Abstract:

Various method embodiments of the present invention concern sensing patient-internal pressure measurements indicative of physiological exertion, identifying one or more steady state periods of physiological exertion based on the patient-internal pressure measurements, sensing extra-cardiac response data and cardiac response data corresponding to the one or more physiological exertion steady state periods, respectively comparing the extra-cardiac response data and the cardiac response data to extra-cardiac response information and cardiac response information associated with equivalent levels of physiological exertion intensity of the one or more steady state periods, and determining the likelihood that myocardial ischemia occurred during the one or more steady state periods based on the comparison of the extra-cardiac response data to the extra-cardiac response information and the cardiac response data to the cardiac response information.
