The Resusci Anne QCPR with Airway Head is a full-body CPR manikin with a rechargeable battery. It simulates a standard adult patient in cardiac arrest (in terms of the chest compression force required). Each Resusci Anne model simulates an adult with average physiology and is designed for realistic Basic Life Support training according to international guidelines. The Resusci Anne QCPR comes in a handy trolley bag. Two additional (light and heavy) chest springs are included with the manikin to vary the compression force required to compress the chest to the target depth, allowing trainees to practice compressions in a more realistic way; as patients' chest stiffness can vary.
