Abstract: This disclosure is directed to devices, systems, and techniques for identifying a respiration rate based on an impedance signal. In some examples, a medical device system includes a medical device including a plurality of electrodes. The medical device is configured to perform, using the plurality of electrodes, an impedance measurement to collect a set of impedance values, where the set of impedance values is indicative of a respiration pattern of a patient. Additionally, the medical device system includes processing circuitry configured to identify a set of positive zero crossings based on the set of impedance values, identify a set of negative zero crossings based on the set of impedance values, and determine, for the impedance measurement, a value of a respiration metric using both the set of negative zero crossings and the set of positive zero crossings.

Abstract: An example device includes memory configured to store a measure of COPD severity of a patient and processing circuitry communicatively coupled to the memory. The processing circuitry is configured to receive an electromyogram (EMG) of the patient, receive one or more signals indicative of respiration rate of the patient, and receive one or more signals indicative of tidal volume of the patient. The processing circuitry is configured to determine, based on the respiration rate of the patient and the tidal volume of the patient, a minute ventilation of the patient. The processing circuitry is configured to determine, based on the minute ventilation of the patient and the EMG of the patient, the measure of COPD severity of the patient, and generate an indication for output that is based at least in part on the measure of COPD severity of the patient.

Abstract: An example device includes memory configured to store an N-dimensional model, where N is equal to a count of a plurality of physiological parameters and processing circuitry communicatively coupled to the memory. The processing circuitry is configured to determine a plurality of signals indicative of physical quantities of the patient and to process the plurality of signals indicative of physical quantities of the patient to determine a plurality of physiological parameters of the patient. The processing circuitry is configured to process the plurality of physiological parameters of the patient to the N-dimensional model to determine a chronic obstructive pulmonary disease (COPD)-exacerbation risk score and determine whether the COPD-exacerbation risk score satisfies a threshold. The processing circuitry is configured to, generate an indication for output that is based at least in part on the COPD-exacerbation risk score satisfying the threshold.

Abstract: An example device includes memory configured to store a first impedance and a second impedance each associated with a heart of a patient, and processing circuitry communicatively coupled to the memory. The processing circuitry is configured to determine at least one of a measure of hematocrit, an indication of fluid overload, or an indication of true anemia based at least in part on the first impedance and the second impedance. The processing circuitry is configured to output an indication of the measure of hematocrit, the indication of fluid overload, or the indication true anemia.
