Qi resistance is a pathological change of qi resistance in zang-fu organs and meridians. Qi stagnation is mostly caused by wind-cold, damp-heat and phlegm. Trapped in zang-fu organs or meridians, making a tunnel lose its patency. If the heart is closed, it will be delirious and crazy, and the spirit will faint and spasm; If the chest and lungs are blocked by qi, chest obstruction will lead to chest obstruction, wheezing and hoarseness; If the bladder is closed, urine will be blocked; Constipation caused by large intestine gas closure; Qi obstruction in meridians leads to joint pain. Among them, the most serious is closed heart coma. Generally speaking, closed syndrome mainly refers to stagnation of heart-qi.
Qi depression is one of the pathogenesis of qi deficiency, and it is a pathological change characterized by the weakness of qi movement. Most of the air traps are further developed due to qi deficiency. Spleen ascending is healthy, and spleen deficiency is easy to be depressed, which is often called "depression of middle qi" The relatively constant position of the internal organs of the body depends entirely on the normal up-and-down movement of qi. Therefore, when the lifting force is weakened due to qi deficiency, some internal organs will droop.
Qi deficiency refers to a pathological change in which qi deficiency is extremely serious and is in danger of loss and extinction. Due to the serious loss of qi, blood and body fluid in the body, the physiological function of zang-fu organs is extremely declining, and the true qi leaks out, which is on the verge of extinction. Loss of qi can be divided into collapse and sudden loss: the gradual consumption of essence leads to extreme failure of viscera function, which is collapse; Exhaustion of essence; What causes yin exhaustion and yang death is violence detachment.
