摘要:
An event-based approach to collecting and organizing information associated with events affecting respiration is presented. The detection or prediction of an event affecting the respiration of a patient initiates acquisition of information associated with the event. The respiratory logbook system acquires information associated with the event during the event and during intervals proximate in time to the event. The information is organized as a respiratory log entry. The user can access the information by operating a user interface. The information may be presented in textual or graphical form.
摘要:
Method and systems are directed to acquiring and organizing information associated with at least one syncope event. A syncope event may be a suspected syncope event, a verified syncope event or a syncope event that is suspected and verified. Automated processes are used to collect information associated with at least one syncope event and organize the information as a syncope log entry. At least one of acquiring the information and organizing the information is performed at least in part implantably.

摘要:
Disordered breathing events may be classified as central, obstructive or a combination of central an obstructive in origin based on patient motion associated with respiratory effort. Central disordered breathing is associated with disrupted respiration with reduced respiratory effort. Obstructive disordered breathing is associated with disrupted respiration accompanied by respiratory effort. A disordered breathing classification system includes a disordered breathing detector and a respiratory effort motion sensor. Components of the disordered breathing classification system may be fully or partially implantable.
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:
Patient respiration may be characterized using a marked respiration waveform involving a respiration waveform annotated with symbols, markers or other indicators representing one or more respiration characteristics. A respiration waveform may be acquired by sensing a physiological parameter modulated by respiration. A marked respiration waveform may be generated based on the acquired respiration waveform and one or more detected respiration waveform characteristics and/or respiration-related conditions. One or more components used to generate the marked respiratory waveform may be fully or partially implantable.

An approach to collecting and organizing information associated with events affecting sleep is presented. The sleep logbook system may acquire information associated with the sleep during periods of sleep and/or during periods of wakefulness. The information is organized as a sleep logbook entry. The user can access the sleep information by operating a user interface. The information may be presented in textual or graphical form.
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:
Systems and methods involve an implantable device configured to perform at least one cardiac-related function, a patient-external respiratory therapy device, and a communication channel configured to facilitate communication between the implantable device and the respiratory therapy device. The implantable and respiratory therapy devices operate cooperatively via the communication channel to provide one or more of patient monitoring, diagnosis, and therapy. The communication channel may be configured to facilitate communication between an external processing system and at least one of the implantable device and the respiratory therapy device. The processing system is communicatively coupled to at least one of the implantable and respiratory therapy devices via the communication channel to provide one or more of patient monitoring, diagnosis, and therapy.
摘要:
Systems and methods provide for detecting snoring, and for determining the presence of sleep disordered breathing using detected snoring. Snoring indicative signals generated by one or more patient-internal or external sensors are detected. The presence of sleep disordered breathing is algorithmically determined, patient-internally or externally, using the snoring signals. Algorithmically determining presence of sleep disordered breathing may include computing a snoring index developed from the detected snoring. Sleep apnea may be detected using the snoring index. Sleep apnea may be verified using internal or external sensors. A positive airway pressure device may operate cooperatively to verify and treat sleep disordered breathing.
