Abstract

Ventricular fibrillation was induced in dogs, external heart massage was applied from the 2nd, 3rd, 4th, 5th, 6th and 10th min after the beginning of fibrillation, and blood flow in the cerebral cortex, renal cortex liver and skeletal muscle was determined by Aukland's hydrogen polarographic method. As compared to the original value, an about 50% (33.4±4.2 ml/min/100 g) flow could be maintained in the cerebral cortex by external heart massage started in the 2nd min. If it was started later, severe circulatory deterioration ensued. Heart massage begun in the 2nd min ensured in the renal cortex only 18% (33.8±5.4 ml/min/100 g) of the normal flow, while in the liver a flow of 15.2±3.8 ml/min/100 g tissue. Skeletal muscle flow dropped during massage below the limit of detectability. Thus, during heart massage, blood flow was different in the different organs. For the maintenance of an effective capillary flow, a perfusion pressure of at least 60 to 80 mm Hg is required.
