Lung scaling is generally for advanced pneumoconiotics, such as long-term stonemasons, coal miners, and these dust workers. Lung scaling is required if the patient has symptoms such as severe decline in lung function, dyspnea, recurrent respiratory infections, and ineffective treatment after the use of respiratory machines in the advanced stage of pneumoconiotics. Lung scaling is only available in large tertiary hospitals, and the cost is around RMB 20,000, which varies according to the charges in each hospital area. The exact number of lung scaling sessions depends on the actual condition of the patient, and the cost of the treatment will also increase if there are other complications in combination. Therefore, a lung wash needs to be based on the patient’s main symptoms, lung function tolerance, the cost of about 20,000 yuan, can have part of the effect of alleviating the clinical symptoms, but you can not put your hope entirely on the lung wash.
