Question
Hemoglobin (Hb) and oxygen gas form a complex (HbO2) that carries oxygen throughout the human body. Unfortunately, carbon monoxide also binds to hemoglobin so that an equilibrium is established. Carbon monoxide poisoning occurs when the concentration of HbO2 in the blood is reduced.
HbO2 + CO--> HbCO + O2
The first aid for a person suffering from carbon monoxide poisoning is to (1) remove them to an area of fresh air, and (2) administer oxygen. Using the principles of equilibrium, explain how each of these helps to restore the HbO2 concentration.
Explanation / Answer
Both steps attempt to serve the same purpose: Increase the amount of O2 in the system. Increasing the O2 level causes the equilibrium to shift to the left, causing more HbO2 to form and CO to be released. Moving the person to fresh air allows the CO to escape to an area that will not be harmful to the patient nor the health care provider.

HbO2 + CO <--> HbCO + O2
Shifting of equilibrium towards left increases the formation of HbO2 which is required to be restored.As he is moved to fresh air CO escapes in air decreasing CO which forms the compound.
