Systems and methods for contactless control of a physiological monitor are provided. A number of systems utilize an input device for audio-based control of a physiological monitor and/or an input device for gesture-based control of a physiological monitor. Many systems process audio (e.g., voice) or gesture commands to direct a physiological monitor to perform actions, such as begin monitoring, silencing an alarm, changing parameters, navigating screens and/or menus, and/or any other function. Such contactless systems reduce or eliminate physical contact with a physiological monitor, which can mitigate contamination between patients or individuals, which can occur via traditional systems.

A diagnostic Electrochemical Impedance Spectroscopy (EIS) procedure is applied to measure values of impedance-related parameters for one or more sensing electrodes. The parameters may include real impedance, imaginary impedance, impedance magnitude, and/or phase angle. The measured values of the impedance-related parameters are then used in performing sensor diagnostics, calculating a highly-reliable fused sensor glucose value based on signals from a plurality of redundant sensing electrodes, calibrating sensors, detecting interferents within close proximity of one or more sensing electrodes, and testing surface area characteristics of electroplated electrodes. Advantageously, impedance-related parameters can be defined that are substantially glucose-independent over specific ranges of frequencies. An Application Specific Integrated Circuit (ASIC) enables implementation of the EIS-based diagnostics, fusion algorithms, and other processes based on measurement of EIS-based parameters.
