... turtles can alter cardiac shunting patterns, which will affect arterial P O 2 values. Consequently, little is known about arterial O 2 regulation and use in undisturbed turtles. We conducted the first study to continuously measure arterial P O 2 using implanted microelectrodes and a backpack logger...

.... A possible functional significance for this intra-cardiac shunt has been debated for almost a century. Unilateral left vagotomy rendered the single effective pulmonary artery of the South American rattlesnake, Crotalus durissus , unable to adjust the magnitude of blood flow to the lung. The higher constant...

... ventilatory cycles are associated with characteristic increases in pulmonary blood flow and tachycardia. In animals with central vascular shunts, the rise in pulmonary blood flow during ventilation is associated with the development of left-to-right (L–R)cardiac shunt (pulmonary recirculation of oxygenated...
