Term
Total lung capacity (TLC)
Definition
Volume of air in the lungs after a maximal (forced) inhale
Term
Vital capacity (VC)
Definition
Max volume of air that can be exhaled after a maximal (forced) inhalation
Term
Inspiratory capacity (IC)
Definition
Max volume of air that can be inhaled after a normal (unforced) inhalation
Term
Expiratory capacity (EC)
Definition
Max vol of air that can be exhaled after a normal (unforced) inhalation
Term
Tidal volume (Vt)
Definition
volume of air inspired or expired during each normal (unforced) ventilation cycle
Term
Inspiratory Reserve Volume (IRV)
Definition
Max vol of air that can be forcefully inahled after a normal inhalation
Term
Expiratory Reserve Vol (ERV)
Definition
Max vol of air that can be forcefully exhaled after a normal exhalation
Term
Functional Residual Capacity (FRC)
Definition
Vol of air remaining in the lungs after a normal (unforced) exhalation
Term
Residual vol (RV)
Definition
Vol of air remaining in the lungs after a maximal (forced) exhalation
Term
Eupnea aka eupneic breathing
Definition
Normal unforced ventilation, where the thoracic volume is regulated by the action of the diaphragm and the intercostal muscles
Term
Obstructive or restrictive pulmonary diseases
Definition
When air passages are obstructed (ie by mucus) or lungs lose their normal elasticity
Term
Dyspnea
Definition
Condition of labored breathing. Person recruits additional muscles to aid ventilation - scalene muscles, sternomastoids and pectoralis major. These muscle groups also used in hyperventilation (ie during excersise)
