What symptom does person anoxia have

summary

Oxygen is one of the necessary conditions for our human survival. If we lack oxygen for a long time, we will not survive. Lack of endogenous oxygen is generally manifested as: dizziness, headache, tinnitus, dizziness, weakness of limbs; or nausea, vomiting, palpitation, shortness of breath, shortness of breath, shortness of breath, rapid heartbeat and weakness. Let's share some experience.

What symptom does person anoxia have

First: normal people occasionally have symptoms of hypoxia. Because the human body has a certain tolerance to hypoxia for a period of time, it is not terrible to occasionally appear hypoxia symptoms, but we should be vigilant for the frequent occurrence of hypoxia symptoms, because oxygen is an indispensable element in our human life activities. People who are in a state of hypoxia for a long time will first reduce their immunity, easily catch a cold and exercise endurance.

Second, normal oxygen metabolism begins with ventilation and gas exchange of respiratory system. Any obstacle in the process of respiration will cause insufficient gas exchange. At this time, the human body will first make a compensatory protective response. Due to the direct effect of nerve reflex or blood gas, it can increase the depth of breathing, and then accelerate the respiratory rate. If the compensatory response can not meet the needs of the body, there will be hypoxia.

Third: the arterial partial pressure of oxygen is lower than the normal level, and the partial pressure of carbon dioxide caused by carbon dioxide accumulation is higher than the normal level. This phenomenon is called respiratory insufficiency. If the arterial partial pressure of oxygen is lower than 60mmhg, or the partial pressure of carbon dioxide is higher than 50rnmhg, it is called respiratory failure. The harm of hypoxia, no matter what the cause of hypoxia, will change the body's function and metabolic state. The nervous system is most sensitive to hypoxia.

matters needing attention

With the aggravation of hypoxia, it is easy to have blurred consciousness, blue and purple skin, lips, nails, decreased blood pressure, dilated pupils, coma; serious even lead to dyspnea, cardiac arrest, hypoxia and asphyxia and death.
