Abstract

A dummy for practicing cardiopulmonary resuscitation (CPR) of a human being comprising a simulation of the thorax and the head and a lungs simulation in the form of a bag which can be inflated through the mouth or nose opening of the head. The thorax is formed by a hollow body of plastic material, which is in air exchange relationship with the atmosphere and which has stiffening ribs which reproduce approximately human ribs. In that arrangement the number and size of the stiffening ribs are so selected that the compressibility and return force of the thorax correspond to those of a human thorax not only in regard to extent but also in terms of their nature and form, and thus provide a particularly good approximation to the behavior of a human thorax.
