Blood redistribution during exercise
WebHypoxia and hyperoxia are both worrisome issues potentially affecting SCUBA divers, but validated methods to monitor these two conditions underwater are still lacking. In this experiment, a volunteer SCUBA diver was equipped with a pulse oximeter to detect peripheral oxygen saturation (SpO2) and a device to monitor the oxygen reserve index … Web•Vascular shunting is the process of redistribution of blood. •Blood diverted to active areas and diverted away from inactive areas. •Occurs through vasoconstriction (narrowing of arteries) and vasodilation (widening of arteries). •Active areas during exercise = brain and working muscles. •Inactive areas = digestive systems.
