Low blood oxygen level, also known as hypoxemia, is a serious health condition that requires urgent medical care. It occurs when the organs and tissues in the body do not get enough oxygen to function properly. Hypoxemia is often the result of a problem with gas exchange in the lungs, although it can have other causes. Some of the most common causes of low blood oxygen levels include:
- Lung diseases such as chronic obstructive pulmonary disease (COPD), asthma, and emphysema.
- Heart diseases such as heart failure and congenital heart defects.
- Sleep apnea.
- High altitudes where the air has less oxygen.
- Anemia, a condition in which the body doesnt get enough oxygen due to a lack of healthy red blood cells.
- Carbon monoxide poisoning.
- Pulmonary embolism, a blockage in the arteries of the lungs.
Symptoms of low blood oxygen levels include shortness of breath, confusion, rapid breathing, chest pain, and bluish skin. If you are experiencing symptoms of hypoxemia, it is important to seek medical attention immediately.
