Other lung function acronyms:
TLC
|
Total lung capacity: the volume in the
lungs at maximal inflation
|
RV
|
Residual volume: the volume of air
remaining in the lungs after a maximal exhalation
|
ERV
|
Expiratory reserve volume: the maximal
volume of air that can be exhaled from the end-expiratory position
|
IRV
|
Inspiratory reserve volume: the maximal
volume that can be inhaled from the end-inspiratory level
|
IC
|
Inspiratory capacity: the sum of IRV
and TV
|
IVC
|
Inspiratory vital capacity: the maximum
volume of air inhaled from the point of maximum expiration
|
VC
|
Vital capacity: the volume equal to TLC
− R
|
VT
|
Tidal volume: that volume of air moved
into or out of the lungs during quiet breathing (VT indicates a subdivision
of the lung; when tidal volume is precisely measured, as in gas exchange
calculation, the symbol VT or VT is
used.)
|
FRC
|
Functional residual capacity: the
volume in the lungs at the end-expiratory position
|
RV/TLC%
|
Residual volume expressed as percent of
TLC
|
VA
|
Alveolar gas volume
|
VL
|
Actual volume of the lung including the
volume of the conducting airway.
|
FVC
|
Forced vital capacity: the
determination of the vital capacity from a maximally forced expiratory effort
|
FEV1
|
Volume that has been exhaled at the end
of the first second of forced expiration
|
FEFx
|
Forced expiratory flow related to some
portion of the FVC curve; modifiers refer to amount of FVC already exhaled
|
FEFmax
|
The maximum instantaneous flow achieved
during a FVC maneuver
|
FIF
|
Forced inspiratory flow: (Specific
measurement of the forced inspiratory curve is denoted by nomenclature
analogous to that for the forced expiratory curve. For example, maximum
inspiratory flow is denoted FIFmax.
Unless otherwise specified, volume qualifiers indicate the volume inspired
from RV at the point of measurement.)
|
PEF
|
The highest forced expiratory flow
measured with a peak flow meter
|
MVV
|
Maximal voluntary ventilation: volume
of air expired in a specified period during repetitive maximal effort
|
