Meaning of Anoxia
The term anoxia refers to insufficient oxygen in the body's tissues or in the bloodstream. It is a process that is related to hypoxia and represents the lack of oxygen in a part of the body or in the whole organism. The lack of oxygenation could be conceived as a pulmonary pathology , among them, acute anoxia, a decrease in hemoglobin that paralyzes the adherence of oxygen in the quantities that are necessary, or also due to stenosis , a decline in blood circulation or anoxia histotoxic an inability of tissues to establish oxygen.
Anoxias are medical pathologies through which the partial or total lack of oxygen in a body tissue originates, although it is also known as the low amount of oxygen that exists in the body's cells.
People who suffer from oxygenation problems generally have lung problems or strong alterations in hemoglobin that do not allow the tissues to have enough oxygen.
It can also be due to decreased blood circulation . But you can also speak of this term as a cerebral anoxia, which is nothing more than an injury to the brain that is caused by a lack of oxygenation.
Cerebral anoxia occurs when the nervous system totally loses its natural oxygen supply, this is also due to a result of hypoxia and anoxia. The affections for the cerebral tissue that last 5 or 6 minutes, produce irreparable damage in the human organism, although there may also be cases in which patients can die.
Causes of anoxia
This disease is caused by lung disease , anemia, heart failure and lack of oxygenation in the brain . If this type of thing occurs on the skin or mucosa, this pathology can generate cyanosis , a type of blackening (color from blue, purple or dark tones) in the affected area.
If the pathology is cerebral, then the results are irreversible. The brain is not able to last too long without oxygen supplies. Perinatal anoxia, prenatal anoxia, or intrauterine anoxia are quite likely .
This is due to the fact that too many painkillers are given to women before and during labor and the stability of the baby or fetus is complicated, this causes the circulation and oxygen supplies to be paralyzed for a few minutes, although it is also possible that these cases when the umbilical cord has been cut before the due time and, consequently, the fetus does not receive the necessary amount of oxygen . Another case is that the fetus wraps the umbilical cord around its neck, this is also called intrauterine anoxia.
Types of anoxia
Of course, there are different types of anoxia , all with different characteristics and with alarming consequences that will be explained below.
Anoxic anoxia
This is produced by a diminished amount of oxygen in the air that is breathed regularly , a classic example of this type of pathology is when someone gets sickle or altitude sickness. People who travel to places where the altitude is too high, tend to have episodes in which they do not receive enough oxygen because that found in the environment is lower than normal.
This type of pathology can also occur in mechanical drowning , by choking or immersion, as well as the different types of physical aggressions that are known today.
Ischemic anoxia
People tend to refer to these pathologies as hypoxia and anoxia , as it is caused by a systematic lack of oxygen in the brain, this as a consequence of changes in blood pressure. This is usually quite common, as well as anoxic encephalopathy or other pathologies such as brain hemorrhages, hypotension , stroke or cardiac arrest.
Anemic anoxia
It is produced by the lack of oxygen in the brain system , but this occurs because there are alterations in the oxygen that must be supplied or that exists in hemoglobin.
Toxic anoxia
It is a type of insufficiency in oxygenation that is produced by harmful substances that prevent the correct use and distribution of oxygen. The causes are varied, but intoxications, narcotics, cyanides, formaldehyde, alcohol, anesthetics and toluene stand out.
Consequences of anoxia
To be able to mention the consequences that this condition generates , it is really important to highlight those situations that trigger pathologies like these or some similar ones, one of them refers to respiratory problems such as asthma, respiratory and cardiac arrest, overdose of alcohol or drugs , inhalation of carbon monoxide, electric shocks, drowning or having any type of reaction to local and general anesthesia.
All these situations are classified as triggers that require urgent treatment by a medical professional.
Now, the consequences or results that trigger this condition range from consciousness, motor or sensory disorders, movement disorders, epilepsy seizures, cognitive and visual disorders and, in extremely strong or traumatic cases, death.
Prevention of anoxia
In order to prevent this condition , doctors were able to determine different aspects that explain the symptoms that a patient with this pathology may have. These symptoms must be treated in time, otherwise, it can lead to severe brain problems and the death of the patient will be caused.
Symptoms range from mood or personality changes, disorientation, trouble concentrating, dizziness, temporary dyslexia, trouble maintaining coordination, and trouble walking properly.
All people should be aware of these symptoms because if the patient spends more time without oxygenation, they will have less chance of life, in addition, with each minute that passes, the symptoms become quite evident, so much so that they can occur from hallucinations to fainting spells. .
