Final answer:
Artificial respiration or oxygenation can save a person's life in certain situations. In carbon monoxide poisoning, the administration of 100 percent oxygen is crucial to displace the CO and restore oxygenation to the body. Giving carbon dioxide would not work and could potentially be harmful.
Step-by-step explanation:
Artificial respiration or oxygenation can potentially save a person's life in certain situations. In the case of carbon monoxide poisoning, the administration of 100 percent oxygen is crucial for the patient's survival. Carbon monoxide (CO) is a toxic gas that binds to hemoglobin in red blood cells, preventing oxygen from binding and being transported throughout the body. By providing 100 percent oxygen, it helps to displace the CO and allow oxygen to bind to hemoglobin, restoring oxygenation to the body.
Giving carbon dioxide (CO2) would not work in the case of carbon monoxide poisoning. Carbon dioxide does not have the same ability to bind to hemoglobin as oxygen does and cannot replace the oxygen molecules that are prevented from binding by carbon monoxide. In fact, administering carbon dioxide could potentially be harmful as it could further reduce the oxygen-carrying capacity of the blood.
