Flashcards in Respiratory System Spirometer Readings Deck (12):
1

Minute ventilation (MV)
def? measured how?

total volume of air inhaled and exhaled each minute
MV equals breathing rate times TV (about 6L/min)

2

Forced expiratory volume (FEV)
def? measured as? used to...?

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

3

Inspiratory Reserve Volume (IRV)
def?

(inhale extra)
amount of air that can be forcefully inhaled after normal TV inspiration

4

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

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

5

Expiratory Reserve Volume (ERV)
def? measure?

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

6

Residual Volume (RV)
def? measure?

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

Vital Capacity (VC)
def? formula? measure?

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

8

Total lung capacity (TLC)
def? formula? WHAT IS THE MEASURE FOR THIS? (on test)

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

9

measurement of air volumes is called?

Spirometry

10

lung capacities
what are they?

they are combinations of specific lung volumes

11

what is used to diagnose restrictive pulmonary diseases?

lung volumes and lung capacites

12

how are spirograms read?

read from right to left!
