output spirometer Flashcards
total lung capacity
= IRV + TV + ERV + RV
vital capacity
IRV + TV + ERV
functional residual capacity
ERV + RV
inspiratory capacity
TV + IRV
Vital capacity
maximum amount of air exhaled after filling lungs to maximum extent possible
Vital Capacity formula
VC = TV + IRV + ERV
or
ERV = VC - TV - IRV
Tidal Volume
amount of air inhaled and exhaled during a single breath at rest
Expiratory reserve volume
maximum amount of air expelled from lungs by exhaling forceful after end of normal tidal volume
Inspiratory reserve volume
amount of air inhaled in excess of normal inspiration during quiet breathing
Inspiratory capacity
maximum amount of air inhaled from the normal end- expiratory level
Expiratory reserve volume antonym
inspiratory capacity
Inspiratory reserve volume formula
IRV = VC - (TV + ERV)
Inspiratory capacity formula
IC = VC - ERV
Total lung capacity
maximum volume of air lung can hold with distended to greatest possible extent
Total lung capacity formula
TLC = VC + RV
