What condition refers to an inadequate supply of oxygen to the tissues?

The condition that refers to an inadequate supply of oxygen to the tissues is known as hypoxia. This term is used to describe a situation where there is insufficient oxygen available for cellular metabolism, which can occur for various reasons, including respiratory issues, circulatory problems, or environmental factors.

In the context of neonatal care, hypoxia is particularly critical because neonates are vulnerable to oxygen deprivation, which can lead to serious complications such as brain injury or organ dysfunction. Understanding hypoxia allows healthcare providers to promptly identify and treat underlying issues, ensuring adequate oxygenation and preventing long-term effects on the newborn's health.

Anemia, while it involves a reduced capacity of the blood to carry oxygen due to a deficiency in red blood cells or hemoglobin, does not specifically define the condition of inadequate oxygen supply to tissues as hypoxia does. Hypercapnia refers to an excess of carbon dioxide in the bloodstream, which might suggest a respiratory issue but does not directly indicate a lack of oxygen. Respiratory distress typically describes a clinical state where the infant has difficulty breathing, which may or may not result in hypoxia. Thus, hypoxia is the most accurate term for the condition of inadequate oxygen supply to tissues.
