Carotid blood flow in anesthetized rats: effects of carotid ligation and anastomosis.


An experimental model was developed for continuous measurement of the common carotid blood flow, in the anesthetized rat, with an electromagnetic flowmeter. The mean carotid blood flow for 41 rats averaged 3.2 +/- 0.2 ml/min at an average mean arterial pressure of 101 +/- 2.5 mm Hg and arterial pO2 of 106 +/- 3.4 mm Hg, pCO2 of 38 +/- 1.2 mm Hg, and pH of 7… (More)
