Of the following oxygen administration devices, which has the advantage of providing high oxygen concentration?
a) Non-rebreather mask
The non-rebreather mask provides high oxygen concentration but is usually poor fitting.
b) Venturi mask
The Venturi mask provides low levels of supplemental oxygen.
c) Catheter
The catheter is an inexpensive device that provides a variable fraction of inspired oxygen and may cause gastric distention.
d) Face tent
A face tent provides a fairly accurate fraction of inspired oxygen, but is bulky and uncomfortable. It would not be the device of choice to provide high oxygen concentration.
