Lack of Oxygen

Hypoxia and hypoxemia occur due to lack of oxygen in the blood. Oxygen deficiency in the organism leads initially to temporary, and then to permanent damage to the function of vital organs.

If all the cells and tissues in the organism functioned normally, it is necessary to maintain a certain concentration of oxygen throughout the body.

Breathing meets the needs of the organism for oxygen, and there are extremely rare conditions when cells can not be used, but take oxygen from the blood.

However, the complex mechanism of its transportation can disrupt respiratory and pulmonary circulatory diseases, hemoglobin deficiency (anemia), cardiac failure, and many other conditions.

If there is not enough oxygen in the arterial blood, there is hypoxemia, and if the deficiency is in the cells and tissues – hypoxia.

These are linked and mutually dependent.

The organism takes over atmospheric oxygen through the lungs  says Assistant Dr. Vladimir Žugić, a pulmonologist, head of the Department of Functional Diagnosis of the Lung of the Clinic for Pulmonology at the Clinical Center of Serbia. – By breathing, oxygen is introduced into the lung alveoli , from where it freely passes into the lung vessels, where it binds to hemoglobin in red blood cells and is further distributed by circulation throughout the body.

An acute lack of oxygen in the blood (acute hypoxemia) occurs in severe conditions of a respiratory or cardiovascular system that starts suddenly, such as severe lung inflammation, severe asthma, myocardial infarction with acute cardiac failure.

It can also occur in conditions of shock and sepsis.
The chronic lack of oxygen in the blood (chronic hypoxemia) is most often encountered in the long-term diseases of the cardiovascular and respiratory system (chronic heart failure, chronic obstructive pulmonary disease, pulmonary fibrosis), neurological diseases or systemic disease of the organism.

The body’s response to the lack of oxygen in the blood is that the existing oxygen in the body is directed to the key organs: brain, heart, liver, kidneys, and at the expense of other organs – explains Dr. Vladimir Žugić. – That’s why we have skin sometimes with a blonde shade, which is best seen on nails.

The cardiovascular system responds by narrowing the blood vessels in peripheral organs and by accelerating cardiac work and, whenever possible, by increasing arterial pressure. Top benefits of banana barks and peelings to our health

Therefore, patients usually have accelerated pulse and variable blood pressure.

The long-lasting lack of oxygen in the organism initially leads to temporary and then permanent damage to the function of the key organs, so in the clinical picture there are neurological disorders, heart failure, cardiac failure, liver and kidney disorders.

Therefore, the symptomology of oxygen deficiency primarily depends on the organ or organ system whose function is damaged.
Treatment of an acute lack of oxygen in the blood is an emergency medical condition, because the organism does not get to adapt to the already mentioned mechanisms. In addition to treating the underlying disease, it is necessary to apply medical oxygen (100 percent concentration) in high flows, precisely to prevent damage to vital organs.

Treating a chronic oxygen deficiency in the blood implies a different strategy. The basic principle is the treatment of a disease that leads to this deficiency. Given the chronic lack of oxygen, in certain patients, after a strict need assessment, chronic oxygen therapy is applied at home.

This is done using devices that concentrate atmospheric oxygen
