Effect of intravenously infused noradrenaline on the cardiovascular system of cold-acclimated rats.

Total metabolism, body temperature and basic circulatory parameters (the heart rate, blood pressure, blood oxygen content and hind limb blood flow) were measured in anaesthetized cold-acclimated male laboratory rats exposed to the calorigenic action of noradrenaline. In addition, cardiac output, the oxygen extraction coefficient and peripheral vascular resistance were calculated from these data.
