Aid To Bloodless Surgery Invented
Experiments on dogs have proved the practical'value of a remarkable artificial lung-heart unit constructed by Professor Clarence Crafoord, famous Swedish heart specialist, and a Stockholm engineer. The unit is used for oxygenation of blood diverted from the heart, leaving the latter free for practically bloodless surgical incisions. > The machine consists of an automatic pump for circulating the blood, in combination with a contrivance for eliminating carbon dioxide, which is personally done in the lungs. From previous experiments Professor < Crafoord has found that the bloodstream can be arrested for as long as 20 or 25 minutes without' injurious effects, provided that the blood circulation in the brain can be maintained in some manner or other. The brain cannot do without oxygen for more than a few minutes, or irreparable damage or death will ensue.
