Which one of the following setups on the bag-valve mask (BVM) will enable the EMT to deliver the highest concentration of oxygen to the patient?

Question

Quizplus · Accepted Answer

Using a BVM with an oxygen reservoir attached and receiving oxygen at 15 lpm will provide the highest concentration of oxygen to the patient. The reservoir bag will fill with oxygen during exhalation and deliver a higher concentration of oxygen during inhalation. Using room-air oxygen, as in A, will not provide any additional oxygen. Using oxygen at 15 lpm without a reservoir bag, as in B, will not provide as high a concentration of oxygen as using oxygen with a reservoir bag. Using a BVM with a reservoir bag but not receiving supplemental oxygen, as in D, will not provide as high a concentration of oxygen as using oxygen at 15 lpm with a reservoir bag.
