Systems and methods for monitoring physiological parameters during diathermy

Disclosed is a system for monitoring physiological parameters during a medical interventional procedure involving high intensity/energy radiofrequency electrical currents/voltages applied through a body of a subject, the system including an electrode-based sensor, configured to close an electrical conduction path passing through a body of a subject, and one or more non-electrode-based sensors, a plurality of electrical lines, a monitor, and a filter array including EMI filters mounted at specific locations and characterized by a frequency response curve having a magnitude of an attenuation in a first frequency range (typical of operating frequencies of high intensity/energy radiofrequency medical interventional equipment), which is greater than a magnitude of an attenuation in a second frequency range (typical of the sampling frequencies of the electrode-based sensor and the one or more non-electrode-based sensors), the system being thereby configured for suppressing noise induced by the medical interventional equipment.
