Respiratory protection and countermeasures of COVID-19 epidemic situation

Objective To guide correct selection and use of respiratory protection in the epidemic of Coronavirus disease 2019(COVID-19),and furthermore to promote the research on respiratory protection in the future.Methods The exposure risk,the essential and principles of respiratory protection were discussed in this epidemic,based on the pathogenic characteristics and transmission route of 2019 novel coronavirus.Results The guidelines for correct selection and use of respiratory protection in this epidemic was proposed after the technical standards and key technical parameters of protective masks both in China and abroad were compared.The main problems in use of respiratory protection at present,such as improper selection,in-correct wearing,facial crush injury caused by use of respiratory protection,and no standards available for respiratory protection specific for children,were discussed.Conclusion We should pay attention to the applicability of respiratory protection,optimize the protection process against infectious disease,strengthen the training of individual user,and speed up the research and development of new respiratory protection products.
