Abstract:
1. A device for measuring depth, velocity or rate of CPR chest compressions performed on the thorax of a cardiac arrest victim, where the thorax is characterized by a chest wall, a back and a thickness, said device comprising: a frame sized and dimensioned to fit at least partially around the thorax of the cardiac arrest victim, said frame having an anterior segment and a posterior segment, the anterior segment and the posterior segment joined by an arcuate segment to form said frame, wherein said frame is resiliently biased to an open configuration as large or larger than the thickness of the victim's thorax; an anterior sensor capable of producing a signal corresponding to motion of the chest wall during compressions, said anterior sensor disposed in or on the anterior segment of the frame; a posterior sensor capable of producing a signal corresponding to motion of the thorax during compressions, said posterior sensor disposed in or on the posterior segment of the frame; and a control system operable to receive the signal corresponding to motion of the chest wall and the signal corresponding to motion of the thorax and determine the depth, velocity or rate of chest compressions therefrom.
