Question

Match the device with the appropriate O2 Concentration.

	Nasal Cannula (Flow Rate: 2 L/min)
	Simple Face Mask (Flow Rate: 5-8 L/min)
	Partial Nonrebreather (Flow Rate: 6-10 L/min)

A.	28%
B.	60%-95%
C.	40%-60%

Answer 1

1)Nasal cannula is generally used wherever small amounts of supplemental Oxygen are required, 2 liter/ min ----- 28% of oxygen concentration

2) Simple Face Mask (Flow Rate: 5-8 L/min)------C.40%-60%

A simple face mask is usually used to deliver a low to moderate amount of oxygen. It can deliver around 40%-60% oxygen at 6 to 10 L/min. It’s used for people who can breathe on their own but may have low blood oxygen levels.

A simple face mask doesn’t deliver as high of an oxygen concentration as a non-rebreather mask but is safer in the case of a blockage

3) Partial Nonrebreather (Flow Rate: 6-10 L/min)------B.60%-95%

A partial non-rebreather face mask fits over your mouth and nose and attaches with an elastic band around your head. The mask is connected to a plastic reservoir bag filled with a high concentration of oxygen.
