Simulation illustration and aerosol concentration measurements. The negative airflow face tent evacuation system was placed on an airway manikin in two positions, on the forehead and below the chin. A forceful cough was simulated using an aerosol nebuliser while simultaneously emptying a resuscitator bag. The face tent was attached to a high-efficiency smoke evacuation system which, when turned on, evacuated the visible aerosol into the face tent and away from the simulated healthcare provider (see video). (Top) Different negative airflow tent positions for aerosol-generating medical procedures (AGMP).
