Dual sensor electrodes for providing enhanced resuscitation feedback

A medical system for assisting a user in providing resuscitation care for a patient, comprising:

• a first electrode assembly comprising a therapy side configured to sense ECG signals and deliver a therapeutic shock and a first motion sensor, and
• a second electrode assembly comprising a therapy side configured to sense ECG signals and deliver a therapeutic shock and a second motion sensor;
• an output device;
• and
• at least one processor operatively connected to the first motion sensor, the second motion sensor, and the output device, the at least one processor configured to:
• receive and process signals from the first motion sensor and the second motion sensor to determine a placement orientation of the first motion sensor and the second motion sensor on the patient,
• in response to a determination that the first motion sensor is positioned on a first portion of the patient's anatomy and the second motion sensor is positioned on a second portion of the patient's anatomy in an anterior-anterior orientation, receive and process signals from the first motion sensor without contribution from the signals received by the second motion sensor to estimate compression depth during administration of chest compressions by the user;
• in response to a determination that the first motion sensor is positioned on a first portion of the patient's anatomy and the second motion sensor is positioned on a second portion of the patient's anatomy in an anterior-posterior orientation, receive and process signals from the first motion sensor and the second motion sensor to estimate compression depth during administration of chest compressions by the user,
• cause the output device to provide chest compression feedback for the user based on the estimated compression depth,
• receive and analyze the ECG signals sensed by the first and second electrode assemblies to determine if a shockable rhythm exists;
• and
• configure the medical system to generate a therapeutic shock if a shockable rhythm is present.
