Causes 84 oxygen saturation brain damage

Breathing and lack of oxygen

The oxygen saturation of the blood is in the normal range between 94 and 98 percent. If the value is lower, one speaks of a lack of oxygen in the blood (hypoxemia). This can manifest itself as a feeling of weakness, dizziness and general malaise. Depending on the duration of the condition, breathing and pulse are accelerated. Those affected can experience shortness of breath even with low exertion, chest pain, tremors, sweating, alternating feelings of heat and cold, as well as altered perception and even loss of consciousness. The symptoms are often quite diffuse and unspecific. In order to prevent organ damage due to long-term oxygen deficiency, a quick medical clarification of the symptoms is recommended.


If hypoxemia is suspected, the immediately available carbon dioxide and oxygen pressure in the blood are measured using a blood gas analysis, using easily available, since it is inexpensive, bloodless oximetry, only the oxygen saturation of the red blood cells is measured - however, this can result in incorrect values ​​in the case of circulatory disorders in the fingers Show. A lack of oxygen in the blood can have many causes, such as reduced oxygen levels in the surrounding air, anemia, COPD or other lung diseases and cardiovascular diseases. Treatment for lack of oxygen in the blood depends on the cause diagnosed.
