Final answer:
The administration of 100 percent oxygen helps save a patient from carbon monoxide poisoning by increasing oxygen concentration in the bloodstream. Giving carbon dioxide wouldn't work as it doesn't have the same affinity for hemoglobin as carbon monoxide.
Step-by-step explanation:
The administration of 100 percent oxygen helps to save a patient from carbon monoxide poisoning by increasing the oxygen concentration in the bloodstream. Carbon monoxide (CO) is a toxic gas that binds strongly to hemoglobin, reducing its ability to carry oxygen. Giving the patient 100 percent oxygen helps to displace the carbon monoxide from hemoglobin and restore normal oxygenation.
Giving carbon dioxide would not work to treat carbon monoxide poisoning because carbon dioxide does not have the same affinity for hemoglobin as carbon monoxide. In fact, carbon dioxide is a waste product that is normally produced by the body during cellular respiration and is transported by the blood back to the lungs to be exhaled. Administering carbon dioxide would not address the underlying problem of carbon monoxide toxicity.
