biostudies-literatureUnknown12(9)Nishimura H<h4>Background</h4>The pandemic of COVID-19 caused confusion in medical settings because of increased patient load, and caused many infections among medical staff which occurred through exposure to bio-particles discharged from patients. The risk of exposure became maximum at the examination of patients, particularly in the collection of respiratory specimens. Effective interventions to reduce the risk are needed.<h4>Methods</h4>A one-person booth consisting of curtain walls, frames, and fan-HEPA filter-unit (FFU) was designed. Using the airstream from/to FFU, it has dual functions as a positive/negative pressure machine to prevent pathogens in patient's cough to reach the medical staff inside/outside the booth, respectively. The curtain walls and positioning of the patient and staff were Journal of thoracic disease4633-4642https://www.ebi.ac.uk/biostudies/studies/S-EPMC7578461biostudies-literatureDevelopment of positive/negative pressure booth generating airflow for protection of medical staff from contagious respiratory pathogens.PMC7578461Nishimura HSakata SfalseDevelopment of positive/negative pressure booth generating airflow for protection of medical staff from contagious respiratory pathogens.<h4>Background</h4>The pandemic of COVID-19 caused confusion in medical settings because of increased patient load, and caused many infections among medical staff which occurred through exposure to bio-particles discharged from patients.
