Device for treating an individual suffering from cardiac insufficiency, cardiac arrest, circulatory arrest or stroke

A system providing treatment of cardiac arrest by withdrawing blood from a patient's or an animal's circulatory system during the cardiac arrest and introducing at least modified blood containing the withdrawn blood to which at least one substance has been added to provide whole body reperfusion of the circulatory system with the modified blood during the treatment of cardiac arrest comprising:

• blood analysis means, for connection during the treatment to the blood withdrawn from the circulatory system, for determining during the treatment of the cardiac arrest, at least one parameter of the blood representing a current condition of the patient or animal in cardiac arrest and an output representing the determination during the treatment,
• storage means for storing during treatment of at least two substances from which the at least one substance is selected for treating the cardiac arrest,
• means for selecting during the treatment, based on the output, a type and quantity of the at least one substance from the storage means which is added to the withdrawn blood to form the modified blood, which upon introduction into the circulatory system during the treatment of cardiac arrest lessens or prevents ischemic tissue damage;
• and
• means for introducing during the treatment at least the modified blood into the circulatory system which provides the whole body reperfusion of the circulatory system to treat the cardiac arrest and which lessens or prevents the ischemic tissue damage during the treatment.
