Official title

An Observational Study to Investigate the Aerosol Particle Distribution During Aerosol Generating Procedures

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Massive number of clinicians were infected during the outbreak of COVID-19, which raised the concerns of utilizing "aerosol generating procedures", particularly the use of high-flow nasal cannula, noninvasive ventilation, intubation, bronchoscopy examination and pulmonary function test. There appears to be a trend to avoid those treatments. Instead, aggressive intubation might cause shortage of medical devices and add extra workload. Therefore, we aimed to do a clinical observational study to evaluate the aerosol generation in these procedures and explore the potential measures to reduce the aerosol generation or dispersion.
