1

The amount of gas that can be forcibly inhaled after a tidal inhalation is known as:

Inspiratory Reserve Volume (IRV)

2

What's a normal Inspiratory Reserve Volume (IRV)?

IRV = 3,000 mL

3

The amount of gas that enters and exits the lungs during tidal breathing is known as:

Tidal Volume (Vt)

4

What's normal Tidal volume is (mL):

Vt = 500 mL

5

The volume of gas that can be forcibly exhaled after a tidal exhalation is known as:

Expiratory Reserve Volume (ERV)

6

What's the normal the Expiratory Reserve Volume (ERV) for a healthy 70-kg male?

ERV = 1,100 mL

7

The volume of gas that remains in the lungs after complete exhalation is known as: 

Residual Volume (RV)

8

What's the normal Residual Volume (RV) for a healthy 70-kg male?

RV = 1200 mL

9

True or False

Residual Volume (RV) can be exhaled from the lungs

False

Residual Volume (RV) CANNOT be exhaled from the lungs

10

The Volume of alveolar gas that serves as oxygen reservoir during apnea is known as:

Residual Volume (RV)

11

The volume above residual volume where the small airways begin to close is known as: 

Closing Volume

12

What's the normal Closing Volume for a healthy 70-kg male?

Variable

13

What do 2 or more lung volumes constitute?

A lung capacity

14

I RV + TV + ERV + RV

equals:

Total Lung Capacity

15

What's normal TLC (mL) for a healthy 70-kg male?

TLC = 5,800 mL

16

IRV + TV + ERV

equals:

Vital Capacity

(TLC minus RV)

17

What's the normal Vital Capacity (VC) for a healthy 70-kg male?

VC = 4,500 mL

18

I RV + TV equals:

Inspiratory Capacity (IC)

19

What's the normal Inspiratory Capacity (IC) for a healthy 70-kg male?

IC = 3,500 mL

20

RV + ERV equals

Functional Residual Capacity (FRC)

21

What's the normal Functional Residual Capacity (FRC) for a healthy 70-kg male?

FRC = 2,300 mL

22

RV+ CV equals:

Closing Capacity

23

What's the normal Closing Capacity?

Variable

(Because Closing Volume is variable)

24

What's the normal Tidal volume in mL/kg?

6 - 8 mL/kg

25

What's the normal Vital capacity in mL/kg?

65 - 75 mL / kg

26

What's the normal Functional residual capacity (FRC) in mL/kg?

35 mL/kg

27

Tidal volume, Vital capacity, Functional residual capacity values in mL/kg are calculated on

A. Ideal body weight

B. Total body weight

A. Ideal body weight

28

In the obese patient, you would calculate tidal volume based on the patient's

A. IBW

B. TBW

A. IBW

29

Selecting a tidal volume based on TBW would result in:

Excessively high tidal volume

30

Lung volumes are

A. ~ 25% smaller in females.

B. ~ 25% larger in females.

A. ~ 25% smaller in females.
