Dual sensor implementations for providing resuscitative chest compression feedback

A system for assisting a user in providing chest compressions to a patient, the system comprising:

• a first electrode configured to measure ECG signals and provide defibrillation shock therapy to the patient;
• a first motion sensor configured to be adhered to the first electrode at a position that is offset from a center of the first electrode and configured for measuring motion of an anterior portion of a thorax of the patient;
• a first housing physically coupled with the first motion sensor and configured to receive at least a portion of at least one hand of the user during chest compressions, the first housing comprising:
• a first frame comprising a base and a first receptacle extending from the base for holding the first motion sensor in place, the first receptacle comprising a substantially semicircular portion, a first leg extending at a first angle from a first end of the substantially semicircular portion toward an edge of the base, and a second leg extending at a second angle from a second end of the substantially semicircular portion toward the edge of the base such that the substantially semicircular portion, the first leg, and the second leg surround the first motion sensor and hold the first motion sensor in place, and
• a padding for receiving at least the portion of the at least one hand of the user during the chest compressions, the padding comprising:
• an overmold encasing the base and the first receptacle of the first frame and the first motion sensor;
• an upper surface;
• and
• a lower surface with a thickness between the upper surface and the lower surface of between about 0.1 inches and about 2.5 inches, the first frame made from a first material having greater rigidity than a second material used to make the padding and configured to position the first motion sensor at a center region of the padding;
• a second electrode configured to measure ECG signals and provide the defibrillation shock therapy to the patient in combination with the first electrode;
• a second motion sensor configured to be adhered to the second electrode and configured for measuring motion of a posterior portion of the thorax of the patient;
• and
• a second housing physically coupled with the second motion sensor and comprising a second frame for holding the second motion sensor in place.
