CPR chest compression monitor with reference sensor

摘要

Methods and devices for chest compression depth measurement for CPR.

主权项

1. A device for assisting resuscitation of a victim during CPR chest compressions comprising:
an anterior sensor disposed on an anterior segment, said anterior segment configured to be held adjacent to an anterior surface of the victim and said anterior sensor operable to produce a first signal corresponding to motion of the anterior surface during compressions; a posterior sensor disposed on a posterior segment, said posterior segment configured to be held adjacent to a posterior surface of the victim and said posterior sensor operable to produce a second signal corresponding to motion of the posterior surface during compressions; a control system operable to receive the first signal corresponding to motion of the anterior surface and the second signal corresponding to motion of the posterior surface and determine compression depth therefrom; and a feedback device configured to provide CPR advisory prompts to a rescuer based on a calculated compression depth, velocity or rate; wherein the anterior segment and the posterior segment are configured to provide active decompression during CPR chest compression cycles.
