Novel Repurposing of a Laerdal® Airway Trainer to Simulate Aerosolization (1090-003992)
CE Hours: 0.25 Session Type: SimVentors
We repurposed a Laerdal® Airway Management Trainer combined with a Hudson RCI® nebulizer and Ambu® bag-valve resuscitator to simulate aerosolization that occurs during breathing, coughing, and respiratory arrest requiring Ambu® bag-valve resuscitation and endotracheal intubation. To do this the lung tube from the Laerdal® trainer was disconnected from the lung and connected to the nebulizer tee where the mouthpiece would typically insert. Tape was used to secure this connection. The other end of the tee was connected to the nebulizer reservoir and this, in turn, was connected to an Ambu® bag-valve via the non-rebreathing valve. Tape was used to cover the exhaust valve of the Ambu® bag-valve, though if available a positive end-expiratory pressure (PEEP) valve could be inserted. Star Lumen® tubing attached to the nebulizer jar was connected to medical air. A saline solution was added to the nebulizer jar. The self-inflating bag of the Ambu® bag-valve was squeezed to create a puff of nebulized air from the mannequin’s mouth. To better visualize this process, Glo Germ™ was dissolved in the saline solution and added to the nebulizer jar. A particle counter was used to take a baseline measurement of the particle size and number in the room prior to and during nebulization.
