Resumen de Exercise-Induced Intrapulmonary Arteriovenous Shunting and Pulmonary Gas Exchange

Michael K. Stickland, Andrew T. Lovering

• Recent research suggests the recruitment of intrapulmonary shunt vessels during exercise, which may contribute to the exercise-induced impairment in pulmonary gas exchange. These findings are consistent with substantial anatomical data demonstrating large-diameter (>25 [mu]m) anatomical shunts in the lung, but are contrary to the considerable functional gas exchange-dependent research that has not detected right-to-left physiological shunt during exercise.
