What is pulmonary cerebral disease, common causes and clinical performance?

Pulmonary cerebral disease is a serious complication caused by chronic pulmonary disease, mainly due to low oxygen and high carbonate haematosis due to respiratory failure.I. Causes1. Chronic obstructive pulmonary disease (COPD)COPD is one of the most common causes of lung cerebral disease. Chronic respiratory inflammation and restriction of air currents contribute to a lack of pneumatic air. As the conditions develop, carbon dioxide retention increases, leading to high carbonate and low oxygen haemorrhage. When CO2 retention exceeds a certain limit, it causes brain blood vessels to expand, increases brain blood flow and increases brain pressure, thereby affecting brain function. For example, many cases of severe COPD caused by long-term tobacco use are prone to co-opulmonary cerebral disease in cases of acute increase.2. Pulmonary heart diseasePulmonary heart disease (pulmonary heart disease) causes pulmonary artery stress due to pulmonary disease, leading to right heart failure. The right heart failure can cause the circulation of blood, while the circulation of blood in the lungs is also affected, and the flue ratio is exacerbated. This further exacerbates oxygen deficiency and carbon dioxide retention and causes lung cerebral disease. The risk of pulmonary cerebral disease is higher, especially when such factors as infection induce an acute increase in pulmonary heart disease.3. Other lung diseasesPulmonary cerebral diseases, such as severe pneumonia, pulmonary fibrosis and bronchial asthma persistence, may also result. For example, during severe pneumonia, lung inflammation is widespread, pneumoconiosis is filled with inflammated seepages and gas exchange functions are severely impaired, resulting in oxygen deficiency and carbon dioxide retention. The pulmonary tissues of pulmonary fibrosis patients are becoming hardened, the pulmonary fibrosis structure is damaged, and the pulmonary respiration function is declining and can also cause pulmonary cerebral disease.II. Clinical performance1. Awareness barriersThis is one of the main manifestations of pulmonary cerebral disease. The patient ‘ s state of consciousness can evolve from sleep addiction and unconsciousness. The early stages may be characterized by infirmity and a high level of sleep during the day, which can easily be woken up, but soon thereafter again. As the disease progresses, it is more difficult to awaken and react to stimuli such as pain. When serious, they go into a coma and do not respond to all kinds of irritation.2. Mental symptomsPatients may suffer from mental disorders, hallucinations, delusions, etc. For example, objects that do not exist, voices that do not exist, or ideas that do not fit into reality. It may also be manifested in irritation, excitement, multilingualism, etc., with more volatile emotions. These psychotic symptoms are due to a lack of oxygen in the brain tissue and the irritation of brain neurons by carbon dioxide retention.3. Symptoms of the nervous systemHeadaches: More common, usually episodic, with varying levels of pain. This is because of the brain vascular expansion caused by carbon dioxide larvae and because of the rise in internal pressure.The piston shiver: this is a typical sign of pulmonary cerebral disease. When the patient’s hands are stretched, there is a fast, irregular shaking of the fingers and wrists, similar to the movement of bird wings. This is due to the effects on neurocell function in the nucleotode area.Dilution or disappearance of thorium reflection: A lack of oxygen and carbon dioxide retention can affect neurotransmission and lead to a change in thorium reflection. Some of the patients may experience a dilution of the thorium reflection, which disappears in serious cases.Pathological Reaction Positive: e.g. Babinsky positive, which indicates damage to the central nervous system.Patients with pulmonary diseases, especially chronic bronchitis, chronic obstructive pulmonary diseases, bronchial asthma and other changes in their state of consciousness, such as sleep addiction, neuropsychiatric symptoms such as headaches and tremors in their hands, need to consider the possibility of pneumococcal cerebral disease and need to be treated in a timely manner.
