摘要:
An implantable respiration monitor can be used to detect disordered breathing or periodic breathing events that can be categorized, such as according to one or more of sleep, exercise, and resting awake states. The categorized frequency of such events can be compared to independently specifiable thresholds, such as to trigger an alert or responsive therapy, or to display one or more trends. The information can also be combined with detection of one or more other congestive heart failure (CHF) symptoms to generate a CHF status indicator or to trigger an alarm or responsive therapy or to display one or more trends. The alert can notify the patient or a caregiver, such as via remote monitoring. The sleep state information can be further categorized according to central sleep apnea (CSA) or obstructive sleep apnea (OSA) events.
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 system, device and method for neural control of respiration are provided. One aspect of this disclosure relates to an implantable medical device for sensing and controlling respiration during incidence of central respiratory diseases. According to various embodiments, the device includes a sensing circuit to receive sensed signals representative of an incidence of a central respiratory disease. The device also includes a neural stimulator adapted to generate neural stimulation signals, and a controller to communicate with the sensing circuit and to control the neural stimulator to stimulate a desired neural target in response to the detection of the incidence of a central respiratory disease. In an embodiment, the device includes a plurality of sensors which are adapted to monitor physiological parameters to detect the incidence of a central respiratory disease and to send signals to the sensing circuit. Other aspects and embodiments are provided herein.
摘要:
A neural stimulation system controls the delivery of neural stimulation using a respiratory signal as a therapy feedback input. The respiratory signal is used to increase the effectiveness of the neural stimulation, such as vagal nerve stimulation, while decreasing potentially adverse side effects in respiratory functions. In one embodiment, the neural stimulation system detects apnea and, in response, adjusts the delivery of the neural stimulation pulses and/or delivers a respiratory therapy treating the detected apnea.
