The reaction of O2 and CO with hemoglobin gives

When carbon monoxide binds to hemoglobin, the entire oxygen-hemoglobin curve shifts to the left as well as down. The leftward shift occurs because when carbon monoxide binds to hemoglobin, it increases the like hood of other unoccupied hence groups binding to oxygen (increases its affinity).
