Temporary reduction in oxygen delivery to the brain is known as what?

• A. Hyperoxia
• B. Hypoxia
• C. Anoxia
• D. Hypercapnia

Answer: (B)

The situation described is hypoxia. It means there is not enough oxygen reaching the tissues, in this case the brain, which can be temporary if ventilation or oxygen levels dip briefly. It differs from hyperoxia, which is too much oxygen; anoxia, which is no oxygen at all reaching the tissues; and hypercapnia, which is elevated carbon dioxide levels rather than a lack of oxygen. In dental care, staying aware of oxygen delivery is important during procedures or sedation, so recognizing hypoxia helps you act quickly to restore normal oxygenation.
