... 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...

... 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...

... period; hence,our experiment was designed to allow evaluation of the effects of net cardiac shunt patterns on heat transfer. It has been suggested that an increased R–L shunt during warming contributes to an increased rate of heating( Tucker, 1966 ), but a comprehensive description of Q̇ pul and Q̇...
