This is not the main reason:
The molecular mass of CO is 28 a.m.u while that of O2 is 32 a.m.u therefore the rate of diffusion of CO is higher than O2 and it enter fast into respiratory track and lungs and causes the deficiency of oxygen.
Added:
(The more important reason is):
CO is about 200 times more reactive to 'ferro'-hemoglobin than O2, so it can hardly be replaced by the available excess of oxygen in air, thus preventing the life-essential O2-transfer to parts of the body like brains and hart & lung muscles.

How do high-altitude locations affect breathing rate?
The amount of oxygen is same. The partial pressure of oxygen is lower at higher altitude. The reason why lungs must work harder is because oxygen is required in the body to supply hemoglobins in the blood. The affinity of hemoglobin to oxygen becomes lower as the partial pressure of oxygen decreases, creating a higher breathing rate in order to acquire more oxygen. Take an example of llama that lives up high in mountains. Their body is well adapted to it, such that their hemoglobin's affinity to oxygen is much higher than that of humans, and does not require extra work in order to acquire more oxygen.
Is electron affinity of N is greater than F?
No, it is not. Electron affinity follows a trend like electronegativity and hence increases as we move from left to right across a period. So, Fluorine has the highest electron affinity among 1st period elements.
Does steel get rust easily?
Yes. The steel is very high affinity for oxygen. The steel is harder than it is oxidized. Need to avoid oxidizing the surface of steel, steel coated with grease or oil can. Or to paint the steel surface.
Why do smaller highly charged ions have a greater affinity for an ion exchange column than larger ions with a smaller charge?
it is the governments fult
How does baby blood differ from adult blood?
fetal hemoglobin differs most from adult hemoglobin in that it is able to bind oxygen with greater affinity than the adult form, giving the developing fetus better access to oxygen from the mother's bloodstream.
Is oxygen has more electron affinity than sulfur?
Yes. Oxygen has greater electron affinity than any other element except fluorine.
How many time greater is the affinity of hemoglobin for carbon monoxide greater than the affinity of hemoglobin for oxygen?
The affinity of hemoglobin for CO is roughly 20,000 times greater than that of oxygen in vitro. In vivo, the affinity of hemoglobin for CO is roughly 200-225 greater than that of oxygen. ------------------------------------------------------------------------------------------------- O2 has stronger bond than CO. Therefore, the oxygen in CO loves the iron in the hemoglobin as iron ends with two electrons which complete the 6 electrons in the oxygen. In vivo, the affinity of hemglobin for CO is about 153 from 141x153/141. by amin elsersawi
Carbon monoxide is a deadly odorless and colorless gas?
Yes, and it has an affinity for hemoglobin 400 times greater than oxygen.
Which has a greater electron affinity fluorine or bromine?
Fluorine has greater electron affinity than bromine, or any other element.
Does a low pH decrease hemoglobins affinity for oxygen?
Yes. This an example of the Bohr effect. If pH is lower than normal (normal is 7.4), then hemoglobin does not bind oxygen as well. The higher the pH, the lower the H ion concentration, the lower the carbon dioxide level, and the GREATER affinity hemoglobin has for oxygen. The binding of oxygen to hemoglobin in the lungs is not affected by changing the pH.
Why sulphur have higher negative electron affinity than oxygen?
Due to small size and high electron density of oxygen compared to sulphur, interelectronic repulsion is higher in oxygen, resulting in less energy being released when an electron is added to oxygen, due to lesser stability after electron is added, which is due to the interelectronic repulsion in the small oxygen atom. Hence electron affinity value is lower. It is an abnormality and exception to the general periodic trend of electronic affinity values.
Does magnesium sodium neon or oxygen have the highest first electron affinity?
Oxygen: It has higher electronegativity than any of the others listed.
Why can carbon be used to extract copper oxide?
Mg is a highly electro positive metal and hence has high affinity towards more electronegative element oxygen and thus ,oxide of Mg is very stable and can not be reduced by carbon (Carbon has less affinity than Magnesium towards oxygen). On the other hand , Zn being moderately strong electro positive metal , it has less affinity towards the more electronegative oxygen atom and its oxide is not very stable and hence can be reduced by Carbon easily (carbon has greater affinity than Zinc towards oxygen).
Why is it that the nitrogen have greater amount than oxygen?
nitrogen is lighter than oxygen
Which has more electron affinity oxygen or chlorine?
Electron affinity of chlorine is far grater than oxygen. For oxygen, its value is 141 KJ/mole whereas for Chlorine, it is 349 KJ/mole. Thus, adding an electron is more favourable in case of a gaseous chlorine atom
What effect does cigarette smoking have on oxygen delivery?
Since oxygen transport requires healthy lungs, the answer would be "Yes." Smoking releases carbon monoxide that has an affinity some 500 times greater than oxygen's for hemoglobin. This binds up the hemoglobin and prevents oxygen transport.
What are the adaptations of a yak?
Indigenous mountain animals like the llama, alpaca, and vicuña in the Andes or the yak in the Himalayas are adapted rather than acclimatized to the low oxygen partial pressures of high altitude. Their hemoglobin has a high oxygen affinity, so that full saturation of the blood with oxygen occurs at a lower partial pressure of oxygen. In contrast to acclimatized humans, these indigenous,...
