Lung Volume and capacities Flashcards
Tidal Volume (VT)
amount of air we breathe out and in each breath
resiting: 0.5L/breath
aerobic activity: 2-4 L/breath
Breathing Frequency (F)
number of breaths per minute
resiting: 8-12 breaths/min
aerobic activity: up to 50-60 breaths/min
Total Lung Capacity (TLC)
Max lung volume.
adv=5-6 L
Ventiltation (VE)
volume of expired air per minute
*VE= VTxF
resiting: 6 L/min
aerobic activity: 150-200 L/min
Residual Volume (RV)
amount of air left in lungs after a MAX exhalation
*emergency air supply
Adv=1 L
Forced Expiratory volume (in Seconds FEV1 FEV2..)
volume of your FVC that can be expiredd in 1,2, or 3 seconds
*greatly affected by gender, age, height, and OBSTRUCTIVE pulmonary disease
Forced Vital Capacity (FVC)
largest volume of air you can possibily expire in a single breath
FVC=TLC-RV
*greatly affected by gender, age, height, and RESTRICTIVE pulmonary disease
Expiratory reserve volume (ERV)
max expired volume after normal expiration
Inspiratory reserve volume (IRV)
max inspired volume after normal inspiration
Functional reserve capacity (FRC)
remaining lung volume after NORMAL expiration
Inspiratory Capacity (IC)
volume between normal expiration and upper limits of TLC
*all different kinds of pulmonary disease can affect this
