Oxygen and Health<\/span><\/h3>\n\n\n\nAccording to physiology, almost 60% of the human adult body is water (H<\/span>2<\/span>O). Due to the presence of oxygen atoms in the molecule of water, we can freely say that 2\/3 of the human body is made up of oxygen. <\/span><\/p>\n\n\n\nOxygen is the most important chemical element for humans, animals, and plants. It is a major constituent of the DNA and supports the respiration process as the most vital function of life. Each of the organs or tissues of the body require different oxygen concentration to maintain proper functioning. <\/span><\/p>\n\n\n\nThe other vitally significant functions of oxygen in our body include:<\/span><\/p>\n\n\n\n\n- Conversion of the food into energy for the body;<\/span><\/li>\n\n\n\n
- Support of the cellular mechanisms;<\/span><\/li>\n\n\n\n
- Boosting of the immune system.<\/span><\/li>\n<\/ul>\n\n\n\n

The Brain and the Oxygen Levels<\/span><\/h3>\n\n\n\nO<\/span>2<\/span> is especially important for the function of the brain, which requires a constant supply of oxygen and glucose to perform its role. Without a steady flow of oxygen to the brain, all the systems of the body would be endangered because the brain could not translate the sensory data adequately and relay them to the corresponding organs and tissues. For this, our brain consumes 25% of all oxygen intake by an adult person. <\/span><\/p>\n\n\n\nWhat Is Cerebral Hypoxia?<\/span><\/h4>\n\n\n\nIn cases when the regular oxygen flow to the brain is interrupted, cerebral hypoxia (or brain hypoxia) can occur. The oxygen in our body can be depleted by: <\/span><\/p>\n\n\n\n\n- Cigarette smoke inhalation (or any other smoke);<\/span><\/li>\n\n\n\n
- Carbon monoxide poisoning;<\/span><\/li>\n\n\n\n
- Cardiac arrest;<\/span><\/li>\n\n\n\n
- Drowning;<\/span><\/li>\n\n\n\n
- Choking;<\/span><\/li>\n\n\n\n
- All other instances where respiration is obstructed,<\/span><\/li>\n<\/ul>\n\n\n\n
The individuals affected by this dangerous and life-threatening condition may experience:<\/span><\/p>\n\n\n\n\n- Dizziness;<\/span><\/li>\n\n\n\n
- Blurring of vision;<\/span><\/li>\n\n\n\n
- Poor judgment;<\/span><\/li>\n\n\n\n
- A decline in cognitive functions;<\/span><\/li>\n\n\n\n
- Memory loss;<\/span><\/li>\n\n\n\n
- Nausea;<\/span><\/li>\n\n\n\n
- Severe headache;<\/span><\/li>\n\n\n\n
- Loss of consciousness;<\/span><\/li>\n\n\n\n
- Complete unawareness of their surrounding;<\/span><\/li>\n\n\n\n
- Unresponsiveness;<\/span><\/li>\n\n\n\n
- Failure of the respiratory function.<\/span><\/li>\n<\/ul>\n\n\n\n

Types of Cerebral Hypoxia<\/span><\/h4>\n\n\n\nThere are four types of cerebral (brain) hypoxia:<\/span><\/p>\n\n\n\n\n- Hypoxic hypoxia<\/b> – A condition when the amount of oxygen supply for tissues is reduced by the partial pressure of oxygen in arterial blood.<\/span><\/li>\n\n\n\n
