A Bag Valve Mask delivers what oxygen concentration (when providing supplemental oxygen)?

A bag-valve mask with an oxygen source and reservoir delivers near 100% oxygen when used with a good seal and adequate flow. The reservoir stores oxygen, so during each ventilatory cycle the patient inhales mostly oxygen-rich air rather than room air. With about 15 L/min flow and a proper seal, the FiO2 approaches 1.0, i.e., 100%. If the seal is poor or flow is insufficient, the concentration drops, but the setup is designed to provide the highest oxygen concentration among common airway devices.
