11 symptoms of low oxygen saturationçã

Low saturation is when oxygen cannot reach tissues throughout the body due to changes in the blood, lung disease, or circulation problems, for example.

Lack of oxygen in the blood, also called hypoxia, is a serious condition that can damage cells and, consequently, increase the risk of death.

The brain is the organ most affected in this situation, as its cells can die in about 5 minutes due to lack of oxygen. Therefore, whenever signs of lack of oxygen are identified, it is important to go to the emergency room as soon as possible.

Symptoms of low saturation

The main symptoms of lack of oxygen are:

  1. Shortness of breath;
  2. Accelerated breathing;
  3. Palpitations;
  4. Irritation;
  5. Dizziness;
  6. Excessive sweating;
  7. Confusion;
  8. Drowsiness;
  9. Fainting;
  10. Cyanosis, which are purple fingertips or lips;
  11. Eat.

To identify the lack of oxygen, the doctor can identify the signs through the physical examination and request tests, such as pulse oximetry or arterial blood gases, for example, which can identify the concentration of oxygen in the bloodstream.

How to measure oxygen saturation

The fastest way to measure oxygen saturation is through a finger oximeter, which is a device that must be placed on the fingertip and which contains a light sensor capable of capturing the amount of oxygen that is circulating in the blood.

In general, he althy people have oxygen saturation above 95%, however this saturation can reach up to 93% in case of flu and cold, which is not a cause for concern. However, when oxygen saturation is lower than 90%, it can be a sign of more serious diseases.
