The bag valve mask simulation demonstrates how a typical self-inflating manual resuscitator bag (commonly known as an Ambu bag) functions. Viewers can see inside the bag and visualize how gas flows inside the bag during inspiration and expiration, visualize failures, and learn how to properly perform and interpret a pre-use check of a self-inflating manual resuscitator. This check can be done with the bag inside its transparent plastic bag to save time during the anesthesia machine pre-use check. Users can adjust the size of the extensible O2 reservoir (corrugated hose at the gas entrainment port) as well as the O2 flowrate and observe their interplay on efficient O2 utilization.
