Measures to prevent hypoxia

This is an automatically translated article.

Hypoxia is a complex pathological process because our body is not supplied with enough oxygen for the normal functioning of the cells, or because of a disease in which the cells of the organization cannot use oxygen. The following insights will help you prevent hypoxia and better maintain your own health.

1. Why does the body lack oxygen?

1.1 Lack of oxygen due to respiration Respiratory deficiency can happen in case the air is thin, there is not enough oxygen for the body to breathe when we fly a plane, climb a mountain or live on a high mountain... Then you may be hypoxic due to altitude - is an acute lack of oxygen when we climb suddenly above 3000m or fly above the limit without or damaged oxygen tanks; or hypoxia due to high mountains - is the phenomenon of acute oxygen deficiency when you climb mountains above 3000m such as traveling or climbing.
1.2 Hypoxia due to pathological causes Some cardiovascular, pulmonary and blood diseases reduce the oxygen carrying capacity of the blood leading to hypoxia causing chronic hypoxia. Cases such as hypotension, heart failure, shock, massive blood loss, atelectasis, pneumonia, hemangioma, atrial septal defect, ventricular septal defect, anemia causing a decrease in red blood cell count and hemoglobin count will affect affect oxygen transport. Hemoglobin disease causes the appearance of pathological hemoglobin (HbS or HgF) that alter the function of oxygen transport; CO poisoning in cases of unburnt coal gas, coal stove in airtight, poorly ventilated room or methemoglobin poisoning.
1.3 Hypoxia due to disorders of cellular respiration Cellular respiration is a complex oxidation-reduction process that occurs by the breakdown of respiratory enzymes into closely related chain reactions. The cause of cellular respiration can be due to lack of substrates (anorexia, diabetes, depression...) causing vitamin deficiency and cellular respiratory enzyme deficiency, or poisoning with substances that inhibit cellular respiration. such as sleeping pills, CO, H2S, As, Fluoride, cyanide, toxins created during infection, toxic tumors...
Therefore, the cause of lack of oxygen in the body is very complicated. In fact, the types of hypoxia are often combined with each other, clinical examination and monitoring of biological signs must be sufficient to detect and provide oxygen, but it is not used in all cases but depends on the needs of the patient. nature and extent, depending on the cause, there is an appropriate treatment attitude.

2. Evolution of hypoxia

Acute hypoxia usually occurs in 3 stages:
The stage of excitement arises when hypoxia is mild: Nerves are in a state of excitement, euphoria, pleasant or smiling, metabolism increases sharply and respiration also increases. Compensatory strengthening The inhibitory phase arises when the lack of oxygen continues, the central nervous system is inhibited at first with protective and defensive properties, manifesting as fatigue, drowsiness, headache, intellectual Memory is reduced, reflexes are decreased, body functions are reduced, material metabolism is also reduced... Stage of exhaustion due to severe inhibition of the central nervous system causes disturbances in the whole body when Severe and prolonged hypoxia, which can lead to irreversible disorders of vital organs (brain, heart, liver, kidney) and death when the O2 blood pressure drops to 40-20 mmHg

3. Measures to prevent hypoxia

Hypoxia due to respiration : We are deprived of oxygen due to respiration in case the air is thin, there is not enough oxygen for the body to breathe when flying high (by plane), climbing mountains or living in high mountains, so, The way to prevent hypoxia is to limit going to high places. Do not let the car start the engine in houses, offices... Avoid putting coal stoves in rooms, bedrooms or burning kitchens in airtight rooms with poor ventilation Lack of oxygen due to cellular respiratory disorders: Oxygen deficiency in rooms In this case, it is necessary to eat enough protein, sugar, fat, vitamins and minerals. Avoid being contaminated with the above chemicals. In addition, you can adopt the following lifestyles and remedies to deal with hypoxia:
Quit smoking: If you have been diagnosed with hypoxia or other lung disease, quitting smoking is one of the first things you need to do to improve your hypoxia

Avoid cigarette smoke: Besides quitting smoking, you also need to avoid places with secondhand smoke or people who are smoking. Because cigarette smoke can cause more damage to the lungs than you smoke. Exercise regularly: Exercise is a really useful thing to do to improve strength and your body endurance Eat, rest properly and become a more active person
