Chapter 22 - Spirometery Flashcards
instrument for measuring respiratory volumes and capacities
spirometer
curve up
inspire
curve down
expire
amount of air inhaled or exhaled with each breath under resting conditions
tidal volume (tv)
amount of air that can be forcefully inhaled after normal tidal volume inspiration
inspiratory reserve volume (irv)
amount of air that can be forcefully exhaled after normal tidal volume expiration
expiratory reserve volume (erv)
amount of air remaining in the lungs after a forced expiration
residual volume (rv)
inspiratory capacity (IC)
IC = TV + IRV
vital capacity (VC)
VC = TV + IRV + ERV
forced vital capacity
gas expelled forcefully and rapidly
vital capacity
gas expelled forcefully and slowly
total lung capacity (TLC)
TLC = TV + IRV + ERV + RV
seconds/breath
breath period
breath rate
60/BP
