1
Q
Vt
A
Tidal Volume
-how much air you inhale
2
Q
IRV
A
Inspiratory Reserve Volume
-how much more you can inhale on top of what you already inhaled (number above tidal volume)
3
Q
VC
A
Vital Capacity
- IRV + ERV + TV
- everything but RV
4
Q
ERV
A
Expiratory Reserve Volume
- how much more you can forcibly exhale
- does not include tidal volume
5
Q
FRC
A
Functional Residual Capacity
- ERV + RV
- cannot be determined by spirometry
6
Q
RV
A
Reserve Volume
- how much air is always in your lungs
- cannot be determined by spirometry
7
Q
IC
A
Inspiratory Capactiy
IRV + Vt
8
Q
TLC
A
Total Lung Capactiy
- IC + FCR
- basically everything combined
- cannot be determined by spirometry
9
Q
Influences on Lung Volume
A
body size, age, posture, sex, ethnicity, obesity, disease
10
Q
Is the volume of CO2 or O2 greater in the blood?
A
CO2
*tissue only adds less than 10% of the CO2 being carried (the kidney adds bicarb, so that accounts for the rest)
11
Q
Do peripheral or central chemoreceptors change firing rate faster?
A
peripheral
