Abstract
Optimum conditions for coronary flow under hypothermia were experimentally investigated on dogs. The control of coronary perfusion by flow rate alone was occasionally accompanied by undesirable side-effects, and adequate perfusion pressure was found to be important in sustaining optimum coronary flow. The most favorable results were obtained at perfusion pressures of 90mmHg at 30&C, 50mmHg at 25°C and 40mmHg at 20°C.
