Abstract

Non-invasive ventilatory support is used in COVID-19 treatment, but little is known about associated virus transport, putting healthcare professionals at risk. This study reveals treatment-related aerodynamics by passive tracer visualisation. All therapies showed extensive jet dispersion, illustrating the risk of droplet-driven transmission that depends on jet-extension and jet-orientation. Aerosol transport is inevitable in non-filtered methods. Further research is needed to guide therapy setup adjustments depending on actual infectious SARS-CoV-2 spread.
