ABSTRACT:
A CPR mannequin for practising cardiopulmonary resuscitation of a human has a simulated human head and neck portion with an air passage extending from a mouth opening to neck opening in an end of the neck remote from the head, and an inflatable simulated human chest portion secured to the neck and having a flexible wall member simulating a chest which rises and falls with inflation and deflation of the chest portion. The inflatable chest portion has an air capacity representative of a lung capacity of a human adult, and a further air passage connecting the air passage in the neck to the inflatable chest portion. The inflatable chest portion has a releasable retainer which operates before release to reduce the air capacity of the chest portion to a column representative of the lung capacity of a human child, the releasable retainer being released by air pressure caused by continued blowing of air into the mouth opening when the chest portion has been inflated to an extent representative of the lung capacity of a human child. The mannequin also has a resiliently compressible simulated human heart portion located beneath the inflatable simulated human chest portion.
