The ultimate purpose of the CPR is to maintain a flow of oxygenated blood artificially into the brain during cardiac arrest to prevent a serious brain damage until the professional hands take over the patient. The BRAYDEN is the first manikin that helps you visualize the effects of CPR. It uses a lighting function which will only illuminate when both compression depth and speed are effective. It helps both the instructor and the end user to visualize what happens to the flow of blood to the brain. BRAYDEN will provide confidence and the ability to the end users, in the event they may have to provide real life CPR to a patient.
