摘要:
Methods and systems for diagnosing disorders, including, for example, disordered breathing, involve sensing one or more of a blood chemistry parameter and/or an expired gas parameter, such as expired respiratory gas concentration, blood gas concentration, and blood pH. Diagnosis of the disorder may be performed by a medical device, such as a respiratory therapy device or a cardiac therapy device, based on implantably detected blood gas/pH concentration/level or externally detected expired respiratory gas concentration. Cardiac and respiratory therapies for addressing the disorder may be adjusted based on the detected parameters.
摘要:
A gas therapy system involves sensing the blood gas concentration of the patient and adapting a gas therapy based on the sensed gas concentration. Disordered breathing may be detected bases on blood gas concentration, and gas or cardiac electrical therapy may be adapted to treat the detected disordered breathing. One or more of sensing the blood gas concentration, detecting disordered breathing, or adapting the therapy may be performed at least in part implantably. The gas therapy is delivered to the patient through an external respiratory device, such as a positive airway pressure device.
摘要:
An approach for predicting disordered breathing involves detecting one or more conditions associated with disordered breathing. The detected conditions are compared to disordered breathing prediction criteria. A prediction of disordered breathing is performed based on the comparison of the detected conditions to the prediction criteria. At least one of comparing the detected conditions to the prediction criteria and predicting disordered breathing is performed at least in part implantably.
摘要:
An evaluation of heart failure status is provided based on a disordered breathing index. Patient respiration is sensed and a respiration signal is generated. Disordered breathing episodes are detected based on the respiration signal. A disordered breathing index is determined based on the disordered breathing episodes. The disordered breathing index is trended and used to evaluate heart failure status. The disordered breathing index may be combined with additional information and/or may take into account patient activity, posture, sleep stage, or other patient information.
摘要:
A posture detection system includes an implantable device and a patient-external respiratory therapy device coupled via a communications channel. At least one of the implantable device and the patient-external respiratory therapy devices includes a posture detector. Posture information is transferred between the implantable device and the patient-external respiratory therapy device. The posture information may be used in connection with sleep detection or to modify therapy delivered by the implantable cardiac device and/or the patient-external respiratory therapy device.
摘要:
Methods and systems are directed to evaluating a pathological condition and involve acquiring muscle movement signals, such as electromyogram (EMG) or accelerometer signals, and detecting the presence of the pathological condition. Methods and systems also provide for detecting sleep-related involuntary muscle disorders and non sleep-related involuntary muscle disorders using muscle movement signals. Drug therapy, transcutaneous electric nerve stimulation therapy, or other therapy may be delivered to treat a detected or diagnosed involuntary muscle disorder.
摘要:
Methods and systems provide an integrated approach to respiratory and cardiac monitoring, diagnosis and/or therapy. A medical system includes one or more cardiac electrodes coupled to an external respiratory therapy device. The cardiac electrodes sense cardiac electrical activity that is used to generate an electrocardiogram (ECG) signal. Cardiac events, such as arrhythmia, myocardial infarction and/or ischemia, may be detected based on the sensed cardiac electrical activity.
摘要:
Methods and systems involve coordinating therapies used for treating disordered breathing. Disordered breathing therapies may include cardiac electrical stimulation therapy and external respiratory therapy as well as other therapies for treating disordered breathing in a patient. The therapies delivered to the patient may be coordinated to enhance effectiveness of the therapy, to reduce therapy interactions, to improve patient sleep, or to achieve other therapeutic goals.
摘要:
A lead system, coupled to an implantable device, is configured for subcutaneous, non-intrathoracic placement relative to a patient's heart. Cardiac activity detection circuitry is coupled to the lead system and configured to detect cardiac rhythms. Disordered breathing detection circuitry is coupled to the lead system and configured to detect disordered breathing. One or both of cardiac therapy circuitry and disordered breathing therapy circuitry may be coupled to the lead system and configured to delivery therapies to treat disordered breathing. Such therapies include cardiac pacing, diaphragmatic pacing, and hypoglossal nerve stimulation therapies. A patient-external respiratory device, such as a positive airway pressure device, may be configured to deliver a disordered breathing therapy. One or more of a patient-internal drug delivery device, a patient-external drug delivery device, or a gas therapy device may be employed to treat disordered breathing.
摘要:
Systems and methods provide for gathering of patient related data during non-sleep periods and modulating a therapy delivered to the patient during sleep using the gathered data. Data associated with a patient is gathered while the patient is awake. A therapy delivered to the patient during patient sleep is adjusted using the acquired data. The therapy delivered to the patient may include one or more of a respiratory therapy, such as a positive airway pressure (xPAP) therapy, a sleep disordered breathing therapy, a cardiac rhythm management therapy, such as a cardiac overdrive pacing therapy, a medication therapy, or a drug delivery therapy. The therapy delivered to the patient may be optimized using the acquired data.
