low blood oxygen level

What are the dangers of low oxygen levels?

Oxygen saturation is a measure of the amount of oxygen in the blood at 100% maximum. Normal blood oxygen levels are measured with a pulse oximeter and range from 95-100%, below 90 is too low. Low oxygen saturation or hypoxemia is a condition that can have serious consequences without proper treatment.

Low blood oxygen levels can result in abnormal circulation and cause the following symptoms:
Shortness of breath.
Rapid breathing.
Chest pain.
High blood pressure.

Shortness of breath

Shortness of breath is one of the symptoms of low oxygen saturation. It represents this dangerous disease that needs immediate treatment. Shortness of breath can also be caused by a variety of factors such as chronic obstructive pulmonary disease. Emphysema and chronic bronchitis are two examples of lung diseases that block enough oxygen to reach the bloodstream. Sustained low oxygen saturation can result in permanent damage that the body cannot breathe. Chronic obstructive pulmonary disease is mainly caused by smoking and causes many deaths every year.


Oxygen supplies energy to the body and cells. Low oxygen saturation deprives the cell of its energy source. Fatigue, sloppiness and muscle weakness are representative symptoms of energy deficiency. The cells are hypoxic and do not respond to the entire supply. If you are experiencing extreme fatigue symptoms, consider whether it is the result of low blood oxygen saturation. You can get this information through a blood test.


Brain function is dependent on oxygen. Brain cells die without oxygen. Low oxygen saturation can cause psychological problems such as confusion of thought and loss of short-term memory. If accompanied by other symptoms such as finger tingling and chronic cough, such as low blood oxygen saturation, should be treated immediately.

High altitude pulmonary edema

This happens when traveling at high altitudes. The thin air here has a low oxygen content and the body quickly becomes hypoxic. Air drying and dehydration can also be a problem. Symptoms include headache, edema, coughing and shortness of breath. This disease can affect anyone who travels to high altitudes and is fatal without proper treatment.

Therefore, low blood oxygen level has a hazard that can not be ignored, it is very necessary to have a fingertip pulse oximeter around.
