Flashcards in Midterm 1 (Duration of flow + AEM) Deck (10):
1

Duration of flow

Cylinder factor x psi / flow = mins

minutes/60 = hours

2

Cylinder factor for E

0.28

3

Cylinder factor for H/K

3.14

4

Air entrainment: what will happen if the jet nozzle size decreases?

Lower FiO2 and higher total flow

why? because you entrain more air.

5

What principle effects air entrainment?

Bernoulii

6

The more air entrained, the less?

FIO2

7

How will Condensation/obstruction in the tubing effect Fio2 and Flow rates

Increase Fio2% and decrease flow rate

8

What is the entrainment ratio for FIO2 40%

3:1

9

What is the entrainment ratio for FIO2 60%

1:1

10

What is the entrainment ratio for FIO2 80%

0.3:1
