The effects of graded changes in oxygen and carbon dioxide tension on coronary blood velocity independent of myocardial energy demand.
In humans, coronary blood flow is tightly regulated by microvessels within the myocardium to match myocardial energy demand. However, …

Role of CO2 in the cerebral hyperemic response to incremental normoxic and hyperoxic exercise.
Cerebral blood flow (CBF) is temporally related to exercise-induced changes in partial pressure of end-tidal carbon dioxide (PetCO2 ); …
