An artificial lung for humans and other mammals inserted within the body or placed externally. The artificial lung comprises an electrically actuated three-way valve, a casing containing parallel loops of oxygenator tubes for oxygenation of blood by an atmosphere of circulating air, and an air circulation driving fan powered by an energizing system. As a safety factor in the event of leakage in the casing, a check valve is inserted in an effluent blood duct from the casing to the aerated effluent blood. Two artificial lungs can be utilized internally as left and right lungs.
