What percent oxygen does a patient receive from a BVM (with O2 flowing at 10-15 LPM)?

A. 50-70 percent
B. 70-80 percent
C. 80-90 percent
D. 90-100 percent

Answer :

Final answer:

A patient receives approximately 90-100 percent oxygen from a BVM with an oxygen flow of 10-15 LPM when used correctly with a full reservoir bag and a tight seal.

Explanation:

The amount of oxygen a patient receives from a Bag-Valve-Mask (BVM) with O₂ flowing at 10-15 LPM (liters per minute) is approximately 90-100 percent. This high concentration is achievable when the reservoir bag is properly attached, fully inflated, and a tight seal is maintained on the patient's face. In contrast, without an oxygen reservoir, or if the seal is inadequate, the oxygen percentage delivered can drop significantly. Healthcare providers are trained to maximize oxygen delivery by ensuring an adequate flow rate, maintaining a good seal, and using a reservoir bag when necessary.
