What is the reaction to hypoxia?
The phrases of the "response to hypoxia" usually concern how internal organs, muscles and cells of the body react when hypoxia is experiencing. As a medical condition, hypoxia occurs when insufficient oxygen enters the body. One observed response to hypoxia is increased activity of the respiratory system, usually observed in human hyperventilation. The speed of breathing becomes fast, the depth of breathing increases and the intervals between the breath decrease to absorb more oxygen. Hyperventilation also allows carbon dioxide to end the body faster, but may be more harmful when it is prolonged because low carbon dioxide levels can also limit blood vessels and prohibit oxygen. When the blood vessels are widespread, the muscles are also more relaxed and blood pressure decreases. In this way, vasodilation acts as a double sword by leaving more oxygen to enter the expansion blood vessels and signal the body to require less oxygen by slowing its activity. That's why a patient whoIt experiences hypoxia, it may suffer from dizziness and muscle numbness, all of which are effects of lower blood pressure and relaxed muscles. In worse cases, fainting and even coma can become.
Unlike vasodillation, muscles and blood vessels in the lungs, which is formally known as "hypoxic lung vasoconstriction" (HPV). This is a way of body to adapt to insufficient oxygen supply. When the lungs are experiencing HPV, they redirect blood flow, especially into alveoli that act as lung air pockets. When more blood is distributed to the alveol, it increases the gas exchange rate in the body and the blood containing oxygen has been better absorbed.
Some geneticists observed that the cellular level also has a reaction to hypoxia. Cells have the ability to "remember" and may document the incident of hypoxia by receiving a "signature". In this way, the cells will remember how the hypoxia should be fought next time. On the other hand, some studies have shown that breast cancer prognosis and ovaries are worse when the cells contain a signature of the occurrence of hypoxia.
The adaptation and response of the body to hypoxia can only help humans in a limited time, so urgent treatment of hypoxia is very important. A person may be dependent on the external supply of oxygen or can be introduced by cardio-pulmonary resuscitation (CPR). In some cases, the person is also provided by fluids through intravenous administration.
