How to increase blood oxygen level

Oxygen in the human circulatory system

The human body has two interconnected blood systems: How to increase the blood oxygen level.

The circulatory system brings oxygen-rich blood from the heart into all body tissues via arteries and leads the now oxygen-depleted blood back to the heart via the veins. How to increase blood oxygen level

However, When breathing, the human lungs fill up with air down to the alveoli. The atmosphere contains mainly water vapor and three gases: Oxygen (O 2 ), carbon dioxide (CO 2 ), and nitrogen (N).

On the side of the body, capillaries, the smallest blood vessels that are part of the pulmonary circulation and carry oxygen-poor blood, border the alveoli. Gas exchange now takes place via the thin membranes of the alveoli and capillaries. However, Oxygen passes from the alveoli into the blood, while the blood releases carbon dioxide into the air in the alveoli.

The oxygenated blood is currently distributed in the body. How much blood arrives in an organ or tissue depends on the blood flow. This can regulate by the body via the vessel width and adapted to the oxygen demand of the organ. Therefore, The cells convert Oxygen into energy to maintain their structure and function. Thus, This creates carbon dioxide, which the tissue releases into the blood and later exhales through the lungs.

Measure oxygen saturation

There are several ways to measure oxygen saturation. Blood can be taken from different vessels via catheters. And the oxygen content can determine via a blood gas analysis. The oxygen partial pressure (PO 2 ) is usually given in the blood gas analysis. This partial pressure is directly related to oxygen saturation.

The measured value of the oxygen saturation is given in percent.

The abbreviation with which the oxygen saturation is specified depends on the measuring location:

sO 2: general oxygen saturation

The San O 2: arterial

S p O 2: pulse oximetry

The S v O 2: venous

S zv O 2: central venous

S VG O 2: mixed venous

Therefore O 2 -sat: abbreviation more commonly used in English-speaking countries for oxygen saturation in general.

What is the normal oxygen saturation?

The average values ​​for oxygen saturation as part of a blood gas analysis or measured with a pulse oximeter are between 94 and 98 percent.

Value too low: When is oxygen saturation critical?

The oxygen partial pressure in the blood and tissue can also decrease as a result. In this case, it is called hypoxia. If there is no oxygen at all, it is anoxia.

How is low oxygen saturation created?

However, Hypoventilation, i.e., breathing that is too shallow. However, Can be responsible for too low saturation values as a result. There is not enough Oxygen in the alveoli for gas exchange. The blood flow in the lungs can also disturb. This means that not enough blood can participate in the gas exchange.

In the case of pneumonia, too oxygen saturation can be reduced. The inflammation causes the alveoli wall to thicken. How to increase blood oxygen level This increases the distance between the air and the blood in the capillaries, which restricts the passage of oxygen and carbon dioxide particles. Less Oxygen passes from the alveoli into the blood, and oxygen saturation drops.

Other diseases that associate with decreased oxygen saturation are: How to increase the blood oxygen level

  • bronchial asthma
  • chronic obstructive pulmonary disease ( COPD )
  • Pulmonary edema
  • Pulmonary embolism
  • Poor tissue circulation or anemia can also manifest as hypoxia. The blood is, therefore, more desaturated, so that venous saturation is lower than expected.

If the fingers are cold, the blood circulation is poor. In this case, the pulse oximeter incorrectly shows too low values when measuring on the finger. How to increase blood oxygen level Therefore, It makes sense to repeat the measurement on a warmer finger.

In addition, the oxygen saturation is slightly reduced in smokers.

Symptoms of low oxygen saturation

The performance of the body is heavily dependent on a sufficiently large supply of Oxygen. 

  • low load capacity
  • shortness of breath
  • Fatigue and exhaustion
  • bluish discoloration of the lips and skin (cyanosis)
  • Fainting and fainting

How can you improve blood oxygen saturation? How to increase the blood oxygen level

However, It is essential to know the cause of the low oxygen saturation to treat. Suppose there is an acute lack of Oxygen. How to increase blood oxygen level It can be helpful to give Oxygen through a mask or nasal cannula. This increases the partial pressure of oxygen in the alveoli and facilitates the transition from the lungs to the blood. However, This increases the oxygen saturation.

If you want to do something yourself for a good oxygen supply for your own body and increase it, you can keep fit with physical training and breathing exercises.

Is oxygen saturation too high – is that possible? How to increase the blood oxygen level

The oxygen saturation cannot exceed 100 percent, and even this value reaches under normal circumstances. However. This can be harmful. On the one hand. The carbon dioxide content in the blood. Which is responsible for the respiratory drive, decreases with increasing oxygen content. On the other hand. However, Oxygen can form so-called radicals that damage the cells and trigger mutations.

Therefore, Too much Oxygen is also harmful in the event of a heart attack. Therefore.

However, With hyperventilation, i.e., increased breathing, the blood’s Oxygen. And carbon dioxide levels also change as described. However. The carbon dioxide content is more influenced by breathing. How to increase blood oxygen level The effect on oxygen saturation is relatively tiny.
