Lack of oxygen in the blood will lead to serious consequences, knowing the cause and the body's response to lack of oxygen will help in timely emergency and prevent dangerous complications.1. Causes of lack of oxygen in the body
There are many causes of hypoxia in the body, specifically:
The respiratory tract is obstructed by obstacles such as swallowing foreign objects, choking, choking on water, diphtheria, tumors in the airways. respiratory (high position), asthma , bronchitis , pneumonia (low position) increases mucus secretion, or the bronchial spasm muscles become swollen, causing the airways to narrow, Reduces oxygen and increases carbon dioxide in the body. The reduced thoracic volume causes the body to lack oxygen due to trauma (scoliosis, broken ribs), spinal cord injury, spinal nerve damage causing paralysis of the respiratory muscles, effusion or pneumothorax . Some diseases affect the diffusion of air in the lungs such as pneumonia, bronchopneumonia, acute pulmonary edema, emphysema. Some circulatory disorders affect the process of transporting oxygen in the blood such as anemia (including acute such as blood loss or chronic such as hemoglobin or carbon monoxide poisoning, nitrite...). At that time, the amount of red blood cells in the blood is reduced, unable to carry out the function of carrying oxygen in the body, causing the body to lack oxygen. Heart diseases, such as congenital heart disease or heart failure, affect oxygenation and oxygen transport throughout the body.

2. Reaction when the body lacks oxygen
Respiratory failure is a common manifestation when the body is deprived of oxygen, the respiratory activity and the oxidation process in the body are disordered and functionally impaired, specifically;
Shortness of breath, rapid and shallow breathing, cyanosis. The body is excited, restless, struggling. Fatigue, sweating, headache, nausea. Heart and pulse palpitations, confusion. Decreased visual acuity, blurred vision. Decreased muscle tone and coordination as well as muscle groups. Psychosis, lethargy, decreased consciousness. Blood pressure increases in the early stages and decreases in the late stages.
3. Indication of oxygen therapy
The body's lack of oxygen will cause damage to most cells and tissues inside the body, especially brain cells... In some cases, especially respiratory failure, therapy oxygen is indicated for treatment. At this time, the patient will be able to breathe gas with an oxygen concentration greater than 21% (higher than normal air conditions) through means such as:
Nasopharyngeal catheter, mask, or cage

Although oxygen therapy has high therapeutic effect, however, patients need to be treated according to indications to avoid the risk of complications such as oxygen poisoning, atelectasis, bacterial superinfection, disease retinal detachment (occurs in premature infants).
The lack of oxygen in the body can lead to respiratory failure and seriously affect health and life, so it is necessary to find out the causes and symptoms of hypoxia for timely emergency treatment.
You can go directly to Vinmec medical system to be examined and accurately diagnosed with brain hypoxia. If you have any questions about the medical examination process at Vinmec, please contact HERE for support.
