title: [Sitting on a chair method for teaching the movement of trunk and arms for chest compression].
abstract: Manikin practice does not teach us how to do chest compression properly. Chest compression and Heimlich maneuver for a lying down subject are methods in which one man uses two hands and body weight. Main difference between them is how to hold arms on the compressed subject's body surface. Chest's elasticity is contributory for chest compression. At first, we can compress it easily by moving our trunk forward because it is not so hard but this can not be done easily because the chest has strong bounding force to our hands. So probably at the bottom, we must apply another force to remain the chest stopping there for a moment besides the force that moves the trunk of the body forward. Latissimus dorsi muscle is most likely to produce that force and it is only used sufficiently when legs are sustained tight. Sitting on a chair, we can move our trunk forward and backward without difficulty and easily pull our arms to our trunk. We advocate that doing the chest compression movement sitting on a chair is a more instructive method for beginners and the public than the manikin practice.
