oxygen delivery systems

Question 1

nasal cannula (low flow)

Answer 1

1-2L/min = 24-28%
3-5L/min = 32-40%
6L/min = 44%
For patients with chronic lung disease, limit rate to the minimum oxygen saturation to maintain a level of 88-92%

Question 2

nasal cannula (high flow)

Answer 2

maximum flow 60 L/min
10L/min = 65%
15L/min = 90%
High flow nasal cannula oxygen delivery is often better tolerated by children than other noninvasive delivery methods.

Question 3

Simple Mask

Answer 3

Low flow
5-8L/min = 40-6-% (5L/min is minimum setting)
This mask is only meant for patients who are able to breathe on their own, but who may require a higher oxygen concentration than the 21% concentration found in ambient air.

Question 4

partial rebreather mask

Answer 4

low flow
8-11L/min = 50-70%
set flow rate so that the mask remains two thirds full during inspiration

Question 5

nonrebreather mask

Answer 5

low flow

10-15L/min = 80-95%

Question 6

venturi mask

Answer 6

high flow 
4-6L/min =24-40% 
blue = 24%
yellow = 28%
white = 31%
green = 35%
pink = 40%
orange = 50%
