Pathogenic heat injury lung based on pathogen accumulation and damage with aging: main pathogenesis of elderly pneumonia

Based on the clinical research practice and combined with relevant research results, from the aspect of that the deficiency of vital qi due to aging and accumulation of pathogen and damage due to chronic and stubborn diseases is the pathogenesis basis of senile pneumonia, pathogenic heat damage to the lung is the key factor in onset and deterioration of disease, this paper regards that the accumulation of pathogen and damage due to aging and pathogenic heat damage to the lung is the main pathogenesis of senile pneumonia. The accumulation of pathogen and damage due to aging is caused when the aging and chronic and stubborn diseases cause a loss of vital qi, unconsolidation of the lung with defensive qi, and usually complicated dyspeptic disease is caused by the phlegm and blood stasis. Pathogenic heat damage to the lung means that heat toxicity attacking lung. Consequently, phlegm and toxin occurs and body fluid and qi are consumed, which results in the malfunctions of lung. This study provides the theoretical basis for the main therapeutic strategy of the application of strengthening vital qi and detoxication (supplementing qi and nourishing yin) to clinical application.
