This is Symptoms of Lack of Oxygen to the Brain

The Importance of Oxygen to the Brain

The human body needs oxygen to sustain itself. Reduction of oxygen at least one part of the body is known as hypoxia. Total lack of oxygen is known as anoxia. Brain cells would be damaged after 4 to 6 minutes without oxygen. When the flow of oxygen to the brain is cut off, a person will lose consciousness within 10 seconds. Prolonged hypoxia causes brain damage and eventually death.

Side effects of lack of oxygen to the brain

Oxygen carried in the blood to the brain. Anoxic brain damage can occur if:

1. Blood flow to the brain is blocked or slowed. This can happen because:

• Blood clots or stroke-blood flow to an area of ​​the brain is blocked
• Shock and heart problems, such as heart attack-not pumped enough blood to reach the brain effectively

2. Normal blood flow, but blood does not carry enough oxygen. This could happen due to medical conditions such as:

• Lung disease-oxygen difficulty passing from the lungs to the blood
• Chronic anemia is a condition that causes low red blood cells; these cells carry oxygen in the blood

3.  You are exposed to certain toxins or other poisons. For example, carbon monoxide poisoning makes the obstructed blood pick up oxygen.

4. There is a lack of oxygen in the air. This can happen at a height

The brain is the largest oxygen users, though less than 5 percent of body weight. The brain consumes 20 percent of the oxygen the body needs. Cerebral hypoxia is a shortage of needed oxygen to the brain. There are several causes of brain hypoxia, and largely due to an accident or health complications such as smoke inhalation, head trauma, choking, carbon monoxide poisoning, drowning, drug overdose, stroke and strangulation.

Symptoms in cases of mild brain hypoxia did not get special attention, poor decision making and uncoordinated. In cases of severe hypoxia, a person would become unresponsive and fell into a coma, stopped breathing and did not respond to light. If there is only blood pressure and heart rate, people are likely to experience brain death.

Risk factors lack of oxygen to the brain such as:

• Heart Failure (HF)
• Choke
• Almost drowned
• Exposed electrical
• Heart attack
• Cardiac arrhythmias 
• Stroke
• Brain tumors
• The use of illegal drugs (narcotics)

Life expectancy for someone who has suffered from a lack of oxygen depends on how long the person is suffering with no/less oxygen and if there is damage to the brain. People can usually recover fully if they are not aware of a moment. The more time a person spends time in a state of unconsciousness, the less chance for a full recovery. Even if recovered, a person can suffer from psychological and neurological damage, including amnesia, hallucinations and muscle spasms.
