Warming a capillary bed to 42° C increases blood flow by causing vasodilation, not constriction, thereby increasing blood flow well above tissue needs. This increased blood flow also "arterializes" the capillary blood, meaning it makes the blood in the capillaries have oxygen levels more similar to arterial blood.
