Analysis on distribution characteristics and influencing factors of moxa smoke in the traditional Chinese medicine moxibustion diagnosis and treatment room of a provincial-level hospital in Guangzhou City

Abstract

Abstract: Objective To understand the particle size distribution characteristics of moxa smoke and the influencing factors of air quality in moxibustion diagnosis and treatment rooms. Methods From June to July 2023,an aerosol spectrometer was used to sample and analyze the moxa smoke generated by the burning of moxa columns during diagnosis and treatment in the moxibustion diagnosis and treatment room. Real time monitoring was conducted on the particle concentrations of four particle sizes：ultrafine particles,fine particles,inhalable particles,and total particles,and the results were analyzed. Results The particle size distribution of moxa smoke did not change with the changes of acupuncture position and the time of diagnosis and treatment. There was no significant difference in the concentration of particulate matter with different diameter（P>0.05）. The concentration of particulate matter with different particle sizes was related to burning time and ventilation mode,and decreases as the particulate matter concentration reaches its peak during moxibustion stick combustion. The peak ranges of ultrafine particles,fine particles,inhalable particles,and total particles were 664.75-1 774.35,681.17-1 991.25,728.63-2 468.61 and 737.93-2 572.72 μg/m³,respectively. Conclusion The air quality in the moxibustion diagnosis and treatment room is related to the ventilation mode of the treatment room. The smoke produced by the combustion of moxibustion stick is mainly composed of inhalable particles,especially fine particles and ultrafine particles.
