Following are the causes of Hypoxia:
- Reduced blood supply to the brain: This situation can occur when a single blood vessel is blocked or partially hindered, which most of the time gets the same with the stroke issue. It often affects a particular region of the brain, meddling with the functions led by that region.
- No blood supply to the brain: This happens when the blood vessels that supply the brain with blood are entirely hindered in its process, which is extremely rare and generally fatal.
- No blood oxygen: When the body does not hold the capacity to intake oxygen, or the heart or lungs can't properly send the blood with oxygen, the brain and all other organs endure Hypoxia resulting in a rapidly fatal situation.
- Insufficient blood oxygen: Mostly due to illnesses, namely emphysema or a heart attack, the human body can't correctly oxygenate blood as the brain receives less oxygen than it requires to operate properly.
Types of Hypoxia
- Hypoxic Hypoxia: The tissues do not have adequate oxygen because of its inadequacy in the blood flowing to the tissues. It is caused by inadequate breathing and other related causes.
- Stagnant Hypoxia: It is circulatory hypoxia that is caused by insufficient blood flow. Its outcome includes less oxygen that is available to the tissues.
- Anaemic Hypoxia: There is reduced haemoglobin outcome in a reduced capacity of the blood to transport oxygen that is breathed in. Hence, a diminished supply of oxygen exists in the tissues.
- Metabolic Hypoxia: It takes place when there is a higher demand for oxygen by the tissues than generally. Oxygen may have an intake process, carried and used properly by the tissues, but it is still not sufficient due to a condition that contains metabolism. Example: sepsis infection.
