Final answer:
Anoxia is the term used when hypoxia results in a complete deprivation of oxygen supply, leading to severe health consequences such as organ failure. Treatment with 100 percent oxygen is critical in certain conditions, such as carbon monoxide poisoning, as it helps displace carbon monoxide from hemoglobin to restore normal oxygen transport.
Step-by-step explanation:
When hypoxia leads to a complete deprivation of oxygen supply, it is called anoxia. Anoxia occurs in severe circumstances where tissue receives no oxygen at all, which can lead to cell death and failure of affected organs. For instance, in cardiac muscle or brain tissue, anoxia can result in severe impairment of heart or brain function, potentially causing dire health consequences.
The administration of 100 percent oxygen to patients is a critical treatment for conditions such as carbon monoxide poisoning because it helps to displace carbon monoxide from hemoglobin, allowing normal oxygen transport to resume. Unlike carbon dioxide, which is a waste product of metabolism, 100% oxygen therapy increases the concentration gradient of oxygen, enhancing its binding to hemoglobin despite the presence of carbon monoxide.
