|
capacities
|
are made up of 2 or more volumes
|
|
|
volumes are measured using a ______
|
spirometer
|
|
|
tidal volume
|
the volume of air inspired or expired during the breathing cycle. (Breathing at rest)
|
|
|
vital capacity =
|
inspiratory reserve volume
+ Tidal Volume + expiratory reserve volume = ~4800 ml |
|
|
TLC=_______
|
sum of all volumes~6000 ml
|
|
|
inspiratory reserve volume
|
the maximum volume of air that can be inspired from the tidal end-inspiratory level (the peak of the tidal volume cycle)
|
|
|
expiratory reserve volume
|
the maximum volume of air that can be expired from the tidal end-expiratory level (the trough of the tidal volume cycle)e
|
|
|
residual volume
|
the volume of air in the pulmonary apparatus at the end of a maximum expiration. The volume cannot be measured directly, because the pulmonary apparatus cannot be emptied voluntarily
|
|
|
inspiratory capacity
|
the maximum volume of air that can be inspired from the resting tidal end-expiratory level.
IC=TV+IRV |
|
|
vital capacity
|
the maximum volume of air that can be expired following a maximum inspiration.
VC=IRV+TV+ERV |
|
|
functional residual capacity
|
the volume of air in the pulmonary apparatus at the resting tidal end-expiratory level.
FRC=ERV+RV |
|
|
Total lung capacity
|
the volume of air in the pulmonary apparatus at the end of a maximum inspiration.
TLC=IRV+TV+ERV+RV |
