Highlights
Aeromedical transport of COVID-19 patients creates exposure risk to clinicians and non-medical aircrew
Airflow characteristics in fixed-wing and rotary-wing aircraft vary depending on environmental control system settings
Physical barriers were observed to limit airflow movement from the cabin to the cockpit in both aircraft types
Patient positioning may decrease the risk of exposure to aircrew positioned in the cockpit
Understanding cabin airflow movement can assist in flight planning
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
