1
Q
Minute ventilation (MV)
def? measured how?
A

total volume of air inhaled and exhaled each minute

MV equals breathing rate times TV (about 6L/min)

2
Q

Forced expiratory volume (FEV)

def? measured as? used to…?

A

rate of exhalation
usually measured as the volume of air forcefully exhaled in 1 sec
used to diagnose obstructive pulmonary diseases

3
Q

Inspiratory Reserve Volume (IRV)

def?

A

(inhale extra)

amount of air that can be forcefully inhaled after normal TV inspiration

4
Q
Tidal Volume (TV)
def? WHAT IS THE MEASURE FOR THIS? (on test)
A

(EX: Tide in & out)
volume of air in 1 normal breath
-approx. 500 mL both male and female!

5
Q

Expiratory Reserve Volume (ERV)

def? measure?

A

Amount of air that can be forcefully exhaled additionally after normal TV expiration
1,200 mL

6
Q
Residual Volume (RV)
def? measure?
A

amount of air that remains in lungs at all times (after exhalation) (can’t use this to breathe, like underwater)
1,200 mL
(can’t be measured w/ spirogram, use other test)

7
Q
Vital Capacity (VC)
def? formula? measure?
A

max amount of exhaled after max inhale
VC=TV+IRV+ERV
4,800 mL

8
Q

Total lung capacity (TLC)

def? formula? WHAT IS THE MEASURE FOR THIS? (on test)

A

max amount of air lungs can hold (max inhalation)
TLC=VC+RV
6,000 mL !

9
Q

measurement of air volumes is called?

A

Spirometry

10
Q

lung capacities

what are they?

A

they are combinations of specific lung volumes

11
Q

what is used to diagnose restrictive pulmonary diseases?

A

lung volumes and lung capacites

12
Q

how are spirograms read?

A

read from right to left!
