Estimating FiO2
The flow rate of a simple oxygen mask when the estimated FiO2 is 0.50-0.60.
What is 7-8 L/min?
The flow rate range of a low-flow nasal cannula
What is 1-6 L/min?
The estimated FiO2 for a non-rebreathing mask at 12 L/min.
What is 0.80?
The common types of low flow oxygen devices (5).
What are low-flow nasal cannula, transtracheal catheter, simple oxygen mask, partial rebreathing mask, and non-rebreathing mask?
This low-flow device reduces O2 use by ≈ 50%
BONUS: What are the two types of this device?
Reservoir Cannula
BONUS: Moustache, Pendant
The two benefits of using a high-flow nasal cannula
What is:
Flushes out CO2 from upper airway
Increases expiratory pressure (improves lung inflation)
