So let's wrap this up. Nasal cannula, simple face mask, and reservoir mask are examples of
low-flow oxygen delivery methods. Now the nasal cannula provides FiO₂ concentrations of
approximately 24%-40%. Remember that a lot of it depends on the patient's individual
variables. A simple face mask can be set between 5 and 10 liters per minute which is about
35%-55% FiO₂. Partial rebreathers and non-rebreather masks are considered reservoir masks.
A non-rebreather delivers the highest concentration of oxygen and it has the difference of
valves on the mask and in the piece in between the mask and the reservoir. Thank you for
