1. Frequency
• How many respiratory cycles you have per minute
• F
• Units: breaths/min
• Normal: 12-15/min
2. Tidal Volume
• The amount of air inspired and expired during normal, quiet respiration
• VT
• Units: L/breath
3. Expired Minute Volume
• The amount of air exhaled in one minute of breathing
• VE=VT x F
• Units: L/min
4. Inspiratory Reserve Volume
• The amount of air forcefully inspired above and beyond normal inspiration
• IRV
• Units: L
5. Inspiratory Capacity
• The maximal amount of air that can be inspired after a normal expiration
• IC=VT+IRV
• Units: L
6. Expiratory Reserve Volume
• The amount of air forcefully expired beyone normal expiration
• ERV
• Units: L
7. Expiratory Capacity
• Themaximal amount of air that can be expired after a normal inspiration
• EC=VT+ERV
• Units: L
8. Vital Capacity
• The maximal amount or air that can be forcefully expired after a maximal inspiration
• VC=IRV+ERV+VT
• Units: L
9. Residual Volume
• The amount of air remaining trapped in the lungs after a forceful expiration
• RV=VC x 0.25
• Units: L
10. Total Lung Capacity
• The sum total of air the lungs can contain
• TLC=VC+RV
• Units: L
11. Functional Residual Capacity
• The amount of air remaining in the lungs after a normal expiration
• FRC=ERV+RV
• Units: L
12. Forced Expiratory Volume
• The amount of air forcefully expired in 1 second
• FEV1
• Units: L
13. Forced Expiratory Volume/Capacity
• FEV1/FVC
• Units: %
• Normal: 75-80%
