Tidal volume | volume of air entering or leaving the lungs during a single breath |
inspiratory reserve volume | volume of air that can be inspired over and above the resting tidal volume |
expiratory reserve volume | volume of air that can be expired after a normal expiration |
residual volume | volume of air remaining in the lungs after a maximal expiration |
inspiratory capacity | maximum volume that can be expired after a maximal inspiration |
vital capacity | maximum volume that can be expired after a maximal inspiration |
functional residual capacity | volume of air left in the lungs after a normal expiration |
total lung capacity | volume of the lungs when fully inflated |
Respiratory rate | number of breaths per minute |
minute ventilation | total volume of air expired per minute |
dead space | volume of inspired air that is not available for gas exchange |
alveolar ventilation | volume of air that reaches the alveoli per minute |
asthma | chronic inflammatory disease typically caused when allergens or other irritating substances cause swelling in the lining of the trachea and bronchial tubes |
