Hypoxia – Symptoms, Causes, Definition, Treatment, Types

Hypoxia – Symptoms, Causes, Definition, Treatment, Types

What is Hypoxia?

This is a state of the human body where the body tissues are hungry for oxygen. It is oxygen shortage in the body. In the most extreme hypoxia, oxygen is totally missing from the body which is a condition known as anoxia. Four kinds of hypoxia include:

Hypoxemic Hypoxia
In this type, the oxygen pressure of the blood which goes to the body tissues is much too low to push and flood the hemoglobin with oxygen

Anemic Hypoxia
In this type, the total quantity of hemoglobin is much too small and so the ability of the blood to carry oxygen is much too low

Stagnant Hypoxia
In this type, blood is or can be typical but the blood flow to the tissues is reduced or is not distributed evenly

Histotoxic Hypoxia
In this type of hypoxia, the cells of the tissue are poisoned and because of this poisoning, the cells are unable to make use of oxygen properly

Diseases of the heart, circulation, blood as well as the lungs can all cause some type of hypoxia.

Hypoxia Symptoms

Often the signs or symptoms of hypoxia are not readily recognized because hypoxia is subtle in the onset. The symptoms and signs are normally different in each person and often will not occur in the same order as listed below. Because of this, it is important to be conscious of all the symptoms and signs.

Signs include:

  • Breathing which is rapid

  • Cyanosis

  • Coordination becomes poor

  • Lassitude/lethargy

  • Poor judgment

Symptoms include:

  • Hunger for air

  • Dizziness

  • Muscle as well as mental fatigue

  • Headache

  • Nausea

  • Cold or hot flashes

  • Visual impairment

  • Tingling

  • Euphoria

Hypoxia Causes

A main cause of hypoxia which must be discussed is often referred to as altitude sickness. Individuals who travel to altitudes higher in the mountains from lower altitudes can be affected by the oxygen levels which are decreased in the air they breathe. This can result in fatigue, nausea, headache as well as shortness of breath. Individuals who suffer from altitude sickness should rest, drink lots of fluid and stop or slow down their ascent to the higher altitudes so that the body can adjust to the oxygen levels step by step. detect diseases at an early stage symptoms, and find out the causes and treatments best suited.

There are many other situations which can also cause generalized hypoxia. Individuals who use nitrous oxide as well as other forms of inhalants as recreational drugs are at a great risk of decreased oxygen levels in the body. Those individuals with problems affecting breathing for instance asthma, sleep apnea or emphysema can be also develop hypoxia. There are also complications which happen from the use of anesthesia which may lead to deprivation of oxygen in the body. Another cause can also be heart failure.

Stagnant hypoxia which is also known as Ischemic hypoxia may affect many different areas of the body as well as cause tissue damage. This is a serious type of hypoxia especially when there is loss of oxygen to the brain – leading to irreversible, severe damage to that organ. Some causes which can affect the brain include strangling, suffocation or choking. Arteries which are blocked and lead to the head can also be blamed. Blood clots as well as cerebral trauma also can cut off the supply of blood to regions of the brain.

In cases of Histotoxic hypoxia, there are cells which are damaged, and therefore are unable to use and absorb oxygen. This can happen often because of overuse of alcohol or drugs. The intake of certain poisons like hydrogen sulfide as well as cyanide can also be a cause of this type of hypoxia.

Some individuals can experience oxygen levels which are decreased because of deformities or hemoglobin deficiency. This condition is also known as carbon monoxide poisoning as well as hypemic hypoxia.

Smoking is also a common cause of hypoxia as it is a common cause of many problems with the body. No matter what illness you read about, you will almost always find smoking as a contributing cause. The most important thing that any individual can do to improve their overall health is to stop smoking.

Hypoxia Treatment

Hypoxia can often be a condition which is fatal. There are a variety of ways to treat hypoxia depending on how severe the hypoxia is. If an individual is suffering from hypoxia, the most important step is to establish an airway by assisted breathing. This individual needs immediately to be taken to the hospital where he can be put on a ventilator to assist with breathing. The heart rate and blood pressure needs to be monitored. They need to be kept in control with the aid of medications as well as plenty of fluids. If there are seizures they need to be suppressed. Fluids as well as medications which are needed can be delivered by intravenous fluids or IV. Often cold blankets can be used to slow down the activity of the cells of the brain as well as decreasing the oxygen need. These should be the immediate first steps in treating hypoxia even before the underlying reason for hypoxia is treated.

Along the pathway to recovery, the individual can experience personality regression, memory loss, hallucinations, and amnesia, twitches as well as muscle spasms.

Recovery is always possible especially when the brain has not been starved for oxygen for a very long period. For this reason, it is important to give air which is adequate and medical aid to the individual who is suffering from hypoxia.
