30. Deliver O2 concentration 40-60 % depend
on flow rate 6 -8 L/min
Easy to use
Requires good fit.
Improve humidification
Dryness is less
31. It is simple mask with reservoir bag
It delivers 50-75 %of oxygen when
flow 8 -11L/min
32.
33.
34. Delivery Oxygen concentration :upto 100%
at 15 L/min
Reservoir bag to entrain oxygen
One way valve : prevent oxygen dilution
Tight seal is essential
Reservoir bag must expand freely
35.
36. Mixes - Air and oxygen
Accurate - Oxygen conc delivery
Colour coded valves
Oxygen conc - 24-40 %

39. COLOUR OF ADAPTER % FIO2
Blue 24
Yellow 26
White 28
Green 30
Pink 35
Orange 40
52. Consider two patient on nasal cannula with 100
% O2 at 2 L/min
Normal pt-PIFR-15L/min
Inspired O2=2L/min(100%)+13L/min(21%)
% of O2 received through device 2/13=15.4%
Sick pt-PIFR-30L/min
Inspired O2 =2L/min(100%)+28ltr/mint(21%)
% of O2 received by sick pt=2/28 =7.1%
