Vt
tidal volume
IRV
Inspiratory reserve volume
ERV
Expiratory reserve volume
RV
Residual volume
IC
Inspiratory capacity
VC
Vital capacity
FRC
Functional residual capacity
TLC
total lung capacity
Tidal volume
volume of air inspired/expired during a single breathing cycle under resting conditions
Inspiratory reserve volume
Max volume of air that can be inspired after a normal inspiration
Expiratory reserve volume
Max volume of air that can be expired after a normal expiration
Residual capacity
Volume of air that remains in the lungs after a maximum expiration
Functional residual capacity
Volume of air in the lungs at the end of a normal expiration (RV+ERV)
Inspiratory volume
Maximum volume of air that can be inspired after a normal expiration (RV+IRV)
Vital capacity
Maximum volume of air that can be expired after a maximum inspiration (IRV+Vt+ERV)
Forced expiratory volume in one second
Volume of air that can be exhaled from the lungs in one second with maximal effort following maximal inspiration
Total lung capacity
Total volume of air in the lungs after a maximum inspiration (VC+RV)
FRC
Functional residual capacity
IC
Inspiratory capacity
VC
Vital capacity
TLC
Total lung capacity
__________ pulmonary disease: associated with increased airway resistance
Obstructive
_________ pulmonary disease: associated with decreased lung compliance
Restrictive
FEV1 < 80% indicates….?
Obstructive pulmonary disease
PEFR
Peak expiratory flow rate
Peak expiratory flow rate:
Maximum rate at which a person can exhale
Minute ventilation
total volume of air entering and leaving respiratory system each minute
