Abstract: Techniques are disclosed for measuring an analyte in a biological system. A system may include a medical device with an electrochemical sensor configured to sense the concentration of a plurality of analytes present in a biological system. Processing circuitry of the system may retrieve, identify, and process a respective signal from a respective work electrode to determine the concentration of a respective analyte. The system may further include an implantable medical device configured to sense a cardiac electrogram (EGM). In some examples, the system may be configured to determine one or more patient-specific relationships between the respective signals of the electrochemical sensor and the cardiac EGM during a first period of time. Based on the patient-specific relationships, the system may estimate concentrations of the one or more analytes corresponding to the respective signals based on the cardiac EGM of the patient collected over a second period of time.

Abstract: Apnea events may be detected based on a primary biomarker, e.g., respiration, in the one or more physiological signals. The apnea events may be characterized as one of an obstructive sleep apnea (OSA) event, a central sleep apnea (CSA) event, or a combination OSA/CSA event based on a secondary biomarker, e.g., a frequency spectrum or a morphology of the respirations in the one or more physiological signals. A first electrical stimulation may be provided to treat OSA in response to a first one or more of the apnea events being characterized as OSA events. A second electrical stimulation may be provided to treat CSA in response to a second one or more of apnea events being characterized as CSA events. A third electrical stimulation may be provided to treat combination OSA/CSA in response to a third one or more of the apnea events being characterized as combination OSA/CSA events.

Abstract: In some examples, an apparatus configured to be worn by a patient for cardiac defibrillation comprises sensing electrodes configured to sense a cardiac signal of the patient, defibrillation electrodes, therapy delivery circuitry configured to deliver defibrillation therapy to the patient via the defibrillation electrodes, communication circuitry configured to receive data of at least one physiological signal of the patient from at least one sensing device separate from the apparatus, a memory configured to store the data, the cardiac signal, and a machine learning algorithm, and processing circuitry configured to apply the machine learning algorithm to the data and the cardiac signal to probabilistically-determine at least one state of the patient and determine whether to control delivery of the defibrillation therapy based on the at least one probabilistically-determined patient state.

Abstract: An example method includes receiving one or more physiological signals; detecting an apnea event based on the one or more physiological signals; determining that the apnea event cannot be characterized as one of a normal, OSA (obstructive sleep apnea), CSA (central sleep apnea), or combination OSA/CSA event; and outputting an electrical stimulation as a default based on determining that the apnea event cannot be characterized as a normal event, an OSA event, a CSA event, or combination OSA/CSA events.

Abstract: A system for sensing one or more physiological traits and obstetric conditions, such as a fertility phase, pregnancy, labor, post-partum conditions, and other conditions related to the reproductive system of the patient. The system may use the one or more physiological traits sensed to define one or more patient attributes for the patient, such as a hormone level, heart rate, blood pressure, respiration rate, temperature, oxygen saturation level, uterine contractions, fluid level, and/or other patient attributes. The system is configured to compare the one or more patient attributes to one or more attribute signs describing a threshold for the one or more patient attributes. The system is configured to issue a communication to the patient and/or a clinician based on the comparisons. The system may be configured to assess and indicate reproductive phases for the patient over a life-cycle from the fertility phase to the post-partum phase.
