What term describes a reading that shows low blood oxygen levels?

The term that describes a reading showing low blood oxygen levels is hypoxia. Hypoxia occurs when there is an insufficient amount of oxygen in the tissues, which can be a result of various conditions affecting the lungs, circulation, or the ability of blood to carry oxygen. When blood oxygen saturation levels drop below normal ranges, this is a critical sign that the body may not be receiving adequate oxygen, which is essential for cellular function and overall health.

On the other hand, euphoria refers to a state of intense happiness or excitement and is unrelated to oxygen levels. Hyperoxia indicates an excess of oxygen in the tissues, which can also be harmful and is not applicable in this scenario. Normoxia, conversely, indicates a normal level of oxygen in the body, so it does not pertain to readings that reflect low blood oxygen levels. Understanding these terms is crucial in clinical settings for monitoring and addressing patients' respiratory and overall health.
