What is anoxia?
In this article, we analyze the most common causes and symptoms of anoxia.
The anoxia occurs when the body or the brain of a person stops receiving oxygen . It is an extreme form of hypoxia. The loss of oxygen in the body or brain can be extremely damaging and even life threatening.
Lack of oxygen can cause serious damage or even death, so anyone who suspects that they may have hypoxia should seek medical attention immediately. Only about 4 minutes are needed without oxygen so that the brain is permanently damaged.
The lack of oxygen in the brain causes neurons to die and may increase the likelihood of brain damage or death.
symptom
Mood changes or personality changes
Difficulty speaking or forgetting words
Weakness
Feeling dizzy or disoriented
Incapacity to concentrate
Memory loss
Headache
Difficulty walking
Problems with coordination
The longer a person is without oxygen, the more apparent the symptoms will be. Experiencing anoxia for several minutes can cause: loss of consciousness, fainting, convulsions or hallucinations.
It is important to keep in mind that the symptoms of anoxia may not be immediately apparent because the brain can compensate for the decrease in oxygen for a few minutes before the symptoms appear.
The initial symptoms may be mild. However, immediate medical attention is vital for cases of anoxia.
Types of anoxia
Anemic anemia
Anemic anoxia occurs when there is not enough hemoglobin in the blood or the hemoglobin present has become ineffective. Hemoglobin carries oxygen throughout the body through the blood and if it can not deliver enough oxygen to the organs, they may stop working properly.
Toxic anoxia
Toxic anoxia prevents the blood from transporting oxygen around the body effectively. It can occur after a person ingests, absorbs or inhales certain toxins or other harmful chemicals, such as carbon monoxide.
Anoxia due to stenosis
Stroke anoxia occurs when blood does not reach the brain or other parts of the body that require blood to function properly. Cardiovascular problems, such as stroke or heart failure, are often the cause of anoxia due to stenosis.
Anoxic anoxia
Anoxic anoxia can occur when there is not enough oxygen available to ensure that the body functions properly. This can happen if a person is at high altitude, with a sudden change in altitude, where there is limited oxygen in the air.
Causes of anoxia
- Heart or respiratory
disease - Strangulation or
suffocation - Drug
overdose - Carbon monoxide or smoke
inhalation - Blood
loss - Irregular heart disease or damaged heart muscles that can not pump enough blood and oxygen to the brain -
Other cardiovascular events, such as stroke cardiac arrest, stroke, or heart failure
- acute asthma attack
- severe electrical shock
- exposure to certain toxic chemicals and poisoning
- high altitudes where oxygen levels are low -
near drowning
- a reaction to general anesthesia
- Inadequate oxygen supply or cardiac arrest under general anesthesia -
Pneumonia -
Low levels of hemoglobin in the blood -
Sickle cell anemia or thalassemia (hereditary anemia that causes destruction of red blood cells).
The anoxic hypoxic brain lesions are very serious and can cause serious and permanent damage. Knowing the symptoms and seeking immediate medical attention is crucial. A quick medical response can help reduce complications and determine the speed and success of recovery.
