Abstract : Heart rate, mean arterial pressure, right atrial pressure, and blood flow in the femoral and in the carotid artery were monitored in cats whose rectal temperatures (T sub r) were raised to 44C. Blood flows reached a maximum at T sub r 42 to 43C. and vascular resistances in these beds reached minimum values in the same temperature range. Right atrial pressure remained negative throughout the hyperthermic episode. The data support the view that circulatory failure found in extreme hyperthermia has a peripheral origin. (Author)
