Abstract
Systems, methods, apparatuses, and software for measuring and determining physiological parameters of a patient are presented. In one example, a physiological measurement system includes a physiological sensor system configured to detect a physiological signal representative of one or more physiological parameters associated with a patient. The measurement system also includes a capacitance system configured to apply one or more electric field signals to the patient and determine a capacitance signal. The measurement system also includes a processing system configured to reduce a noise level in the physiological signal based on at least the capacitance signal.
