Brain hypoxia

Introduction Cerebral hypoxia is a symptom that occurs when the oxygen supply to the brain is insufficient. Cerebral hypoxia Slow thinking, slow response, and sleepy, do not have a lot of physical exertion but feel tired, mentally ill, mood swings, temperament changes, sleepy life can not sleep, in severe cases will be accompanied by a number of cerebral hypoxia. The human body is exposed to symptoms of oxygen concentration less than 18%. Generally, the concentration of oxygen in the atmosphere is about 21%. The biggest victim of hypoxia syndrome is brain cells, because the brain consumes 25% of the total oxygen content in the body. % Symptom manifestation Oxygen concentration 16%: pulse speed, headache, nausea, nausea, concentration Oxygen concentration 12%: weakness, dizziness, nausea, body temperature rise Oxygen concentration 10%: pale, confusion, vomiting, cyanosis (skin blue) Oxygen concentration 8%: lethargic Oxygen concentration 6%: , breathing stopped

Cause

Cause of cerebral hypoxia

Alteration, respiratory disorders, cerebrovascular disease, cervical spondylosis, anemia, Ménière's syndrome, geriatric disease, altitude sickness, etc. Improve cerebral hypoxia: The above-mentioned cerebral hypoxia manifests sudden and often without signs, especially in the morning The incidence of post- and nighttime attacks is high, which seriously affects daily work and life. The method of rapid relief can properly absorb oxygen. In most cases, the symptoms can be alleviated after 0.5~1 hours of oxygen inhalation.

Excessive use of the brain

When we exercise, our breathing will be short, and our heartbeat will speed up, but no one has ever seen anyone who has been working at the desk for a long time. Why? There are two reasons for this: First, long-term mental work will increase the brain's consumption of oxygen, and this excessive consumption of oxygen by the brain does not cause the body's compensatory breathing rate and heart rate to accelerate ( The reason is not clear). Second, however, the brain is sensitive to hypoxia. The hypoxic state that is completely tolerable to other organs of the human body is unforgivable for the brain, and the hypoxic symptoms described above appear.

Our breathing ability is related to the volume of our chest. When we do the thoracotomy, the volume of the thoracic cavity is enlarged, which is conducive to the relaxation of the lungs. When we are in the state of arms extension, the chest is The state of being squeezed is not conducive to the relaxation of the lungs. The chest of the person working at the desk is under pressure for a long time, and even if there is a habit of chest hunchback. Therefore, cerebral hypoxia caused by insufficient ventilation is also one of the reasons that cannot be ignored.

Mental influence

The ups and downs of the business, the endless work tasks, the competition of the company's peers, the competition among the companies, and so on, often have large fluctuations in moods, etc. (large outs, big advances, family life problems, etc. when stocks and financial markets fluctuate greatly) Cause) Long-term exposure to this mental stress or volatility, its lethality is far greater than the impact of the cold virus on the human body, people will become fatigue, resistance decline, irritability, temper, depression, etc., this mental impact The reason for this cannot be explained by medical methods.

1. Cerebral hypoxia: dizziness, headache (migraine), hair swelling (high blood pressure also has similar symptoms), and even more tinnitus, vertigo, sometimes accompanied by nausea and vomiting symptoms.

2. Cerebral hypoxia performance: slow thinking, slow response, and sleepiness.

3. Cerebral hypoxia performance: There is not a lot of physical exertion but it feels tired, heart and soul, mood swings, temperament changes, sleepy life can not sleep.

Differential diagnosis

Differential diagnosis

The diagnosis should be differentiated from the following symptoms:

1. Cerebral ischemia: The transient blood supply to the brain and the appearance of symptoms are called transient ischemic attacks, which is a common acute cerebrovascular disease. Sudden onset of the patient, similar to the performance of cerebral hemorrhage or cerebral infarction, generally returned to normal within 24 hours, often causing a family to stun a battle, but can be repeated. Patients with transient ischemic attack may develop cerebral infarction within 1 to 5 years. A transient ischemic attack occurred in 1/3 to 2/3 of patients with cerebral infarction.

2. Hydrocephalus: Hydrocephalus is a general term for cerebrospinal fluid production or circulatory absorption process, resulting in excessive cerebrospinal fluid volume, increased pressure, and enlarged space occupied by normal cerebrospinal fluid, which in turn increases intracranial pressure and ventricular enlargement.

3. Cerebral edema: When the cerebrospinal fluid circulating in the ventricle is blocked by bleeding due to the passage, the hydraulic pressure causes the brain to swell and press to the brain, causing brain dysfunction (the result is insufficient intelligence), ie Called cerebral edema.
