Abstract

Coronavirus disease 2019 (COVID-19) is transmitted mainly by respiratory droplets and close contact, probably by aerosol. Pulmonary function testing procedures have been associated with an increasing risk of COVID-19 transmission among patients/subjects and medical staffs. Effective prevention and control strategies must be compulsorily implemented to prevent nosocomial infection. This recommendation is intended to be followed by healthcare workers (HCWs) of pulmonary function testing laboratory when COVID-19 is in epidemic. Based on the features of pulmonary function testing, precaution principles and considerations are developed in three aspects of management for HCWs, operating procedure, environment and equipment. Indications of pulmonary function testing should be followed strictly. It is strongly recommended to suspend the test for the confirmed or suspected cases of COVID-19 during the contagious stage, and to postpone the test for other patients if it is not imperative. Medical personnel should mandatorily adhere to the standard stratification of precaution measures. Patients/Subjects should be isolated in a separate area for testing. Disposable in-line filters must be used during pulmonary function testing. Cleaning and disinfection procedures for environment and equipment in pulmonary function testing laboratory should be paid more attention.

新型冠状病毒肺炎(COVID-19)主要通过呼吸道飞沫传播及密切接触传播,也可能会通过气溶胶传播。肺功能检查可增加医务人员和受检者发生COVID-19传播的风险,必须严格执行有效的预防和控制措施以防止院内感染。为了指导肺功能检查室医务人员做好防控工作,本文结合肺功能检查的特点,总结了当前疫情下肺功能检查在医务人员管理、检查流程管理和检查环境物品管理3个方面的要求及注意事项。文中强调在疫情流行期间,必须严格掌握肺功能检查的适应证,强烈建议COVID-19确诊病例或疑似病例在传染期内暂缓检查,其他病患如非病情急需也暂缓检查;肺功能室医务人员应严格执行标准分级防护措施;受试者应在单独区域进行隔离检查;检查时必须使用一次性呼吸过滤器;并重视肺功能检查环境和设备的清洁消毒。.
