Flashcards in O2 therapy Deck (21):
1

What does oxygen increase?

PaO2

2

How does oxygen effect WOB

decreases it

3

Oxygen corrects Hypoxemia and decreases what?

Cardiac output.

4

What are some hazards of O2

Absorption atelectasis
Oxygen Toxicity
o2 induced hypoventilation

5

Indications for O2

Hypoxemia
severe acute myocardial infarction
severe trauma
short term therapy

6

To qualify as a high-flow device, a system should provide at least

60 L/min total flow

7

T/F High flow always exceeds the patients flow and provides fixed fio2.

True

8

Low flow does not exceed the patients flow, variable fio2, because ?

it becomes diluted with air

9

How many liters for low flow

8lpm or less

10

Nasal Canuula - humidifier is used only when the input flow is greater than

4 L/min

11

Nasal cannula is best indicated for.

Best used Patient in stable condition who needs low FiO2; home care patient who needs long-term therapy, low to moderate FiO2 while eating.

12

How do you calculate FIO2 for nasal cannula

22% at 1lpm, add 4% with every liter.

13

Nasal Cannula FIO2

22%-40%

14

Simple mask is indications

Emergencies; short-term therapy requiring moderate FiO2; mouth breathing patients requiring moderate FiO2

15

How many lpm for a simple mask?

5-10 L/min

16

Simple mask FIO2

35%-50%

17

Partial rebreathing mask

Emergencies; short-term therapy requiring moderate to high FiO2

18

Partial rebreathing mask FIO2

40-70%

19

High flow AEM FIO2

24-50%

20

High flow AEM indication

Patients in unstable condition who need precise low FiO2

21

High-flow nasal cannula system indication

Patients of all ages with high or variable VE who need supplemental O2, positive pressure, or humidity
