22. Pathogen and Size Characterization of Aerosols Produced during Aerosol-generating Procedures in COVID-19 Positive Patient Intensive Care Units

Introduction: Airborne transmission of SARS-CoV-2 is thought to be greatest during aerosol-generating procedures (AGP) in the hospital. The true risk posed by AGPs is not well understood. Methods: Aerosol capture and real-time particle size characterization were performed in the medical intensive care unit (MICU) during mechanical ventilation, bi-level positive airway pressure (BiPAP) ventilation, high-flow nasal […]

23. Real-time Monitoring for Aerosol Generation in the Emergency Department using Low-cost PM Sensors during the COVID-19 Pandemic

Introduction: Emergency department (ED) healthcare personnel (HCP) provide acute medical care to the ill and injured. The day-to-day burden of aerosol exposure posed to ED HCP during patient care is not well understood, but remains a concern during the COVID-19 pandemic. Methods: Baseline air quality and aerosol characterization during routine ED patient care and emergent […]
