Causes

Chronic obstructive pulmonary disease is the main underlying cause of pulmonary encephalopathy, which caused chronic pulmonary heart disease accounted for 85% of the common causes leading to pulmonary encephalopathy are:. ① acute respiratory and lung infections, severe bronchospasm, airway mucus obstruction, adding to the already impaired pulmonary function decline further in vivo induced CO2 retention .② iatrogenic factors, such as improper use of sedatives, high concentrations of oxygen, resulting in respiratory depression aggravated CO2 anesthesia; inappropriate use of diuretics dehydration agents, induced sputum viscosity and increase the airway obstruction .③ chronic obstructive pulmonary disease associated with right heart failure, due to cerebral blood volume reduction, increased cerebral anoxia and cerebral metabolic disorders.Brain anoxia


(B) the pathogenesis

1. The effect of carbon dioxide to carbon dioxide is the main brain of cerebral blood flow regulator, when paco2 increased cerebral blood vessels to dilate cerebral blood flow increases, increased vascular permeability, leading to increased intracranial pressure and cerebral edema. There are similar high paco2 nitrous oxide (N2O) anesthetic effects, causing coma.

2. On acid poisoning clinical brain cells common paco2 has reached a very high level, the brain is still pulmonary encephalopathy symptoms, but if the ph of the cerebrospinal fluid once lowered, neuropsychiatric symptoms occur rapidly, hypercapnia respiratory failure, resulting in an increase in blood hydrogen ion concentration, when more than the ability to regulate blood buffering and compensatory range of kidney, causing blood ph drops and respiratory acidosis excess hydrogen ions in the blood slowly through the blood – brain barrier into the cerebrospinal fluid, cerebrospinal fluid ph value decreased, the increase of hydrogen ion concentration within brain cells, leading to brain tissue acidosis.Brain anoxia

3. The role of hypoxic brain cells to hypoxia can lead to anaerobic metabolism of brain cells, resulting in non-volatile acidosis and metabolic acidosis, severe hypoxia can affect the function of brain cells, and even cause irreversible damage to brain cells and death.
