Abstract: A system for monitoring a patient includes one or more processors and a sensor device implemented in circuitry. The system is configured to measure, using the sensor device, an impedance of tissue of the patient and determine, using one or more processors, a physiological parameter comprising at least one of a heart rate, cardiac output, vascular tone, perfusion level, fluid status, respiration effort, or respiration rate of the patient based on the impedance of the tissue of the patient. The system is configured to facilitate therapy, using the one or more processors, based on the determined physiological parameter.
