Topic 3 - Spirometry Flashcards
Flow-Volume Loop
TV
Tidal Volume
Amount of air that normally enters the lungs during regular breathing
ERV
Expiratory Reserve Volume
Amount of air you can forcefully exhale past a normal tidal expiration
IRV
Inspiratory Reserve Volume
Extra amount of air that can be brought into the lungs during forced inspiration
RV
Residual Volume
Air left in the lungs after complete full exhalation
VC
Vital Capacity
Amount of air a person can move into or out of their lungs, sum of TV ERV IRV
FRC
Functional Residual Capacity
Volume of air present in the lungs at the end of regular expiration, sum of ERV RV
FVC
Forced Vital Capacity
Deep inspiration + fast (forceful) expiration, sum of TV ERV IRV
FEV(1,2,3)
Forced Expiratory Volume
Volume of air at 1s, 2s, 3s, of forceful expiration after deep inspiration
Tiffenaeu Index
FEV1/FVC
> 80 % = Healthy
< 80 % = Diseased
BMR Equation
