Title: Pressure-flow relationships in the peripheral circulation of the dog with isoprenaline. Author: Green JF. Journal: Clin Exp Pharmacol Physiol; 1975; 2(2):181-4. PubMed ID: 1139800. Abstract: 1. The effects of isoprenaline on the pressure-flow relationships in the peripheral circulation were studied in five anaesthetized dogs during right heart bypass procedures. 2. Isoprenaline (1 mug/kg per min) produced a significant drop in arterial pressure and arterial resistance. 3. There was a significant decrease in the resistance to venous return which resulted in a significant increase in venous return. 4. The findings suggest that the increase in cardiac output produced by isoprenaline results in large part from dilatation of venous resistance vessels.[Abstract] [Full Text] [Related] [New Search]
