Experiments in the Revival of Organisms (Russian: О́пыты по оживле́нию органи́зма) is a 1940 motion picture, directed by David Yashin, that documents Soviet research into the resuscitation of clinically dead organisms. The operations in the film, as well as the design of the heart-lung machine demonstrated in it, the autojektor, were done by Sergei Brukhonenko, whose work in the film is said to have led to the first operations on heart valves.
