This is a small initial assessment for oxygen administration as well as your familiarity with aspirin. A passing score will be at least an 80%, which is 12 out of 14 questions. After passing this assessment, the EMT must demonstrate how to properly set up an oxygen tank and provide oxygen through a NRB. The EMT must attach the regulator, properly check the pressure, and then flow oxygen through an NRB and attach to a patient (proctor or EMT if they would like, or just explain how to do it).
