bottom: Co(g) is first to bond, while the O2(g) does not
Once the body starts to breath in carbon monoxide [Co(g)] we start to lose oxygen flow in our body. This is because the hemoglobin also bonds to Co(g). Infact, it bonds to the hemoglobin as much as two hundred times better than oxygen. (Worden, 2011)
This means when inhaled, it is bonded to the hemoglobin first and therefore results in a lack of oxygen in our body,(Worden, 2011).
To explain how the poisoning works, we must first give some information on how our body functions normally. According to the work of Dr. Jeni Worden, our body contains red blood cells and a protein within in our blood cells exists called the hemoglobin. The Oxygen we breath [O2(g)] is binded to the hemoglobin and travels through our body. (Worden, 2011).
These Bunsen burners are showing the comparison of complete and incomplete combustion. The first fire results from incomplete combustion and the last one results from complete combustion.
Carbon monoxide (CO) is found in combustion fumes (specifically fumes of incomplete combustion, (CDC, 2013).
Example of Incomplete combustion of Methane:
CH4(g) + 2O2(g) → CO(g) + 2H2O(g)
These fumes can be found in cars trucks stoves and the burning of charcoal and wood, (CDC,2013). Symptoms of carbon monoxide poisoning can include, headaches/chest pain, dizziness, nausea/vomiting and loss of consciousness. (Mayo Clinic Staff, 2012)
Carbon monoxide is a highly toxic and dangerous gas that can cause poisoning if too much is ingested. The reason why is it so dangerous is because it shares many properties with the air we breath.
Some of these similar properties include:
-> colourless
-> odourless
-> tasteless gas
These factors alone show how threatening it is because victims can get severely poisoned without realizing it

For larger amounts of carbon monoxide ingested, more drastic measures need to be arranged.
This includes a technology known as Hyperbaric oxygen therapy (Bose, 2009). What this does is speeds up the process of the Carbon monoxide breakdown in the hemoglobin and delivers oxygen directly to starved tissues. The way this works is by placing a patient in a hyperbaric chamber and giving them treatment under pressure.(Bose,2009)

The treatment of Carbon monoxide poisoning varies depending on the exposure.
When a relatively low amount is ingested, high amounts of pure oxygen gas is pumped into the body. This allows the carbon monoxide to slowly dissociate from the hemoglobin, and form carbon dioxide gas [CO2(g)] and release out our body.(Bose, 2009).
This video done by Jordan explains how the treatment relates to equilibrium and Le Chatelier's principle

The oxygen gas would cause a increase in products which in turn, would cause the system to shift left in order to reach equilibrium. This brings the oxygen gas in our body back to it's original state, while eliminating the carbon monoxide infested hemoglobin. (Worden, 2011).
Le Chaterlier's principle is based pm shifts of equilibrium. Once equilibrium is disturbed, the system is moved either right or left to counteract the change (Athur, 2013).
As Jordan explained in his video, the treatment of pure oxygen gas causes a shift to the left. This forms CO2(g) which we breath out. The carbon monoxide poisoning can be represented with is equation, (Arthur, 2013).
HemoglobinO2 + CO(g) <---------------> HemoglobinCO + O2(g).
