20.500.12556/RUL-136172 Size- and time-dependent aerosol removal from a protective box during simulated intubation and extubation procedures Because the SARS-CoV-2 virus primarily spreads through droplets and aerosols, a protective box could provide adequate protection by shielding medical professionals during the intubation and extubation procedures from generated droplets and aerosols. In this study, size- and timedependent aerosol concentrations were measured inside and outside the protective box in the particle size ranging from 14 nm to 20 µm during simulated intubation and extubation procedures. An improved protective box with active ventilation was designed based on a plastic bag with armholes covered with latex sheets that utilizes a supportive frame. Coughing during the intubation and extubation procedure was simulated using an aerosol generator which dispersed the aerosol powder into the protective box. During the intubation and extubation procedure, the concentration of particles increased inside the protective box but, due to the high negative airflow, quickly dropped to background levels. The particle concentration of all measured particle sizes decreased within the same time frame. No leakage of particles was observed through the armhole openings. The presented protective box design provides excellent protection against generated droplets and aerosols. The decrease in concentration does not depend on the particle size. Outside the box, particle concentration did not change with time. aerosol-generating procedure COVID-19 extubation intubation protective box true false true Angleški jezik Ni določen Članek v reviji 2022-04-14 11:45:22 2022-04-14 11:45:23 2022-09-15 04:13:30 0000-00-00 00:00:00 2021 0 0 Str. 315-324 iss. 1 Vol. 1 2021 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 61 2673-8112 10.3390/covid1010025 93028355 covid-01-00025-v2.pdf covid-01-00025-v2.pdf 1 ADB8D0782BA5B44877806B72A3FB01F2 0a28417d69fa408d51943772e390334b9c128a3184da24a9eec8281baf2e5e46 df868c41-bbd7-11ec-8aca-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=155673 https://www.mdpi.com/2673-8112/1/1/25 0 b0131874-bbd7-11ec-8aca-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=155672 Fakulteta za matematiko in fiziko 0 0 0
