However, if they are not used properly, they will not have any effect. The author gave fluticasone/salmeterol inhalation treatment to uncle Chen, who had a history of chronic bronchitis for 5 years, with symptoms of shortness of breath after activity, and the effect was not particularly obvious. Mr. Zhao said that he had used this drug before, but it had little effect after use, but he felt uncomfortable in his throat. The author immediately took the drug inhalation device and asked Uncle Zhao to “demonstrate” on the spot, the results were very surprising, only to see Uncle Zhao pick up the device, head up to “pour” the drug into the mouth, the author immediately stopped, and then gave Uncle Zhao a demonstration while standardizing the operation, 2 weeks 2 weeks later, Zhao came to the follow-up consultation and his symptoms were significantly improved.
