Definition
Fi02 40-60%/ 5-8L/min
flow rates 5L/min or lower can result in rebreathing C02 |

Definition
60 - 75% Fi02
mask has reservoir bag attach w/no valve, which allows the PT to rebreathe up to 1/3 of exhaled air together w/room air
-->complete deflation during Inspiration = CO2 buildup |

Definition
80 - 95% Fi02/ 10 - 15 L/min to keep the bag 2/3 full during I & E
