The smoker would have elevation of his blood carbon monoxide level and, as a result, would have a reduction of his blood oxygen carrying capacity, the higher the level of CO, the greater the reduction of oxygen in his blood.  At rest at sea level this might not be noticeable but with exercise or at high altitude the reduction of oxygen could restrict physical performance.

CO elevation also interferes with the transfer of oxygen from the blood to the body tissues.  Thus does CO reduce the amount of oxygen getting to all tissues including vital organs and exercising muscles.  If extreme the tissues may be "starved" for oxygen, no matter how fast or deeply a person breathes.

Please do your best to stop smoking.  You will never regret quitting and will reduce your chances of heart disease, emphysema and lung cancer.

Good luck
