Consensus for preventing cross-over infection in the procedure of pulmonary function test under the novel coronavirus pneumonia outbreak: experts from Pulmonary Function Group of Shanghai Respiratory Disease Association of Shanghai Medical Association

Novel coronavirus pneumonia (NCP) is mainly transmitted through respiratory aerosol and contact. This consensus summarizes the key points for NCP prevention focusing on pulmonary function test (PFT) receiver and operator preparation, instrument disinfection, management of special cases and hospital infection control inspection, in order to reduce and prevent cross-over infection. We emphasize that at this important stage for combating NCP, PFT test should be delayed or cancelled. While for those who must receive PFT test, the personnel security and environmental protection should be guaranteed.
