Abstract:
1. A method of training first aid providers in the application of the Heimlich maneuver to a choking victim, said method comprising: providing a compression monitor, comprising: an accelerometer, a signaling mechanism and a microprocessor, operable to receive and interpret acceleration signals from the accelerometer and operate the signaling mechanism, to provide feedback to a first aid provider; wherein the microprocessor is further programmed to convert the acceleration signals into a distance value indicative of displacement of an abdominal area of a mannequin caused by an abdominal thrust, compare the distance value to a desired range, and operate the signaling mechanism to indicate when the distance value is within the desired range; wherein the desired range is 4 to 5 inches; securing the compression monitor to a portion of the first aid provider's hand or wrist which remains in substantially fixed relation to a surface of the mannequin's abdominal area which is to be compressed; operating the compression monitor to determine depth of the abdominal thrust performed by the first aid provider; performing an abdominal thrust on the mannequin; and providing feedback to the first aid provider indicating adequacy of the abdominal thrust.
