Lack of oxygen, called hypoxia, is the reduction of the amount of oxygen required by all tissues in the body. Lack of oxygen in the blood, called hypoxemia, is a serious disease that can lead to significant tissue injury and therefore increase the risk of death. .
The brain is the most damaged organ when this happens, as your cells could die from lack of oxygen in about 5 minutes, so whenever signs of lack of oxygen are identified, such as shortness of air, confusion, tone, fainting. or residual fingers, it’s important to help as much as possible in a health center.
- To identify a lack of oxygen.
- Your doctor will identify signs through a physical exam and laboratory tests.
- Such as pulse oximetry or arterial gasometry.
- To determine the concentration of oxygen in your bloodstream.
- He knows more about oxymetry.
Lack of oxygen in the blood and therefore in tissues can have different causes, including:
It occurs when the amount of oxygen in the air that is not breathed enough, is usually present in areas at higher altitudes at 3000 meters, lower sea levels, lower concentration of oxygen in the air.
This is known as hypobaric hypoxia and can lead to complications such as pulmonary edema from acute cardiogenesis, cerebral edema, dehydration and hypothermia.
Changes in the lungs caused by diseases such as asthma, emphysema, pneumonia, acute pulmonary edema, for example, make it difficult for pulmonary membranes to enter oxygen for blood flow, reducing the amount of oxygen in the body.
There are also other types of situations that prevent breathing, such as neurological diseases or a coma, in any properly functioning lung condition.
Anemia is caused by a lack of hierarchy or vitamins, bleeding or genetic diseases such as sickle cell anemia, for example, that cause a lack of oxygen in the body, even if breathing works properly.
In fact, anemia has a degradation of hemoglobin, which is a protein present in red blood cells, whose function is to capture oxygen in the lungs and distribute it throughout the body.
In this situation, the amount of oxygen in the blood is sufficient, however, it is not possible to gracefully link the bodies to an obstruction, as this occurs during a heart attack when blood circulation is low, caused by heart failure. For example.
Situations such as carbon monoxide poisoning or poisoning caused by certain medications, cyanide, alcohol or psychoactive substances could prevent hemoglobin from sticking to oxygen and prevent oxygen from being caught, causing a lack of oxygen.
Neonatal hypoxia is caused by a lack of oxygen in the baby from the placenta, causing injury to the fetus, a situation that could occur before, during childbirth, by changes in the maternal body, related to the placenta and fetus, resulting in intellectual disability (mental retardation).
There are people who experience certain psychological disorders and when in stressful situations use more oxygen, resulting in signs and symptoms such as shortness of breath, palpitations and confusion.
Under extreme environmental conditions, from cold to heat, oxygen demand increases to maintain metabolism and normal bodily functions, thus reducing tolerance to hypoxia.
Symptoms that indicate a lack of oxygen in the blood include
Lack of air;
Accelerated breathing;
Palpitations;
Irritation;
Dizziness;
Excessive sweating;
Confusion;
Drowsiness;
Weed out;
Cyanosis, which is identified by the tips of the fingers and lips become purple;
With him.
It should be noted that the lack of oxygen located in an organ in the region of the body causes specific lesions in this tissue, causing what is called ischemia and infarction, some examples of this are heart, intestinal, pulmonary or stroke attacks.
In addition, lesions caused by lack of oxygen in the tiles could be reversible due to correction of this problem and cell recovery, however, in some cases, lack of oxygen causes tissue change, causing permanent damage. Know how many major sequences can occur, after a stroke.
Treatment of lack of oxygen should begin with the use of oxygen masks to normalize blood levels, however, the situation will only be resolved by treating the cause.
Depending on the cause, your doctor will tell you specific treatments such as antibiotic use for pneumonia, nebulization in case of asthma, medications to improve lung or heart function, treatment of anemia, or medications for poisoning.
In severe cases where the lack of oxygen is caused by a brain injury that cannot be resolved immediately, artificial respiration will be indicated by mechanical ventilation devices, as they are located in the intensive care unit and sedative medications. The doctor is able to stabilize the patient, respiratory capacity. Depending on what is indicated and the incentive induced.
