what is the difference between lung volumes and lung capacities? - Correct Answer
volumes: measure for obstructive disease
capacities: measure for restrictive disease
alveolar volume formula - Correct Answer VA= VE- VD
(VE= pulm. ventilation)
VD= dead space vetilation
dead space formula - Correct Answer VD/VT = (Paco2 - Peco2)/ Paco2
what is methacholine bronchoprovocation testing used for? - Correct Answer A
bronchial challenge test is a medical test used to assist in the diagnosis of asthma. The
patient breathes in nebulized methacholine or histamine.
tidal volume (Vt) - Correct Answer volume of air inhaled or exhaled during each normal
breath (500ml)
inspiratory reserve volume (IRV) - Correct Answer maximal volume of air that can be
inhaled OVER and ABOVE the inspired tidal volume (3100ml)
expiratory reserve volume (ERV) - Correct Answer maximal volume of air that can be
exhaled after exhaling a normal tidal breath (1200ml)
residual volume (RV) - Correct Answer volume of air remaining in lungs after maximal
exhalation (1200ml)
total lung capacity (TLC) - Correct Answer maximal volume of air in the lings at the end
of a maximal inhalation (RV + Vt + ERV + RV)
(6000ml)
functional residual capacity (FRC) - Correct Answer volume of air present in the lung at
end-expiration during tidal breath (RV + ERV)
(2400ml)
inspiratory capacity (IC) - Correct Answer max volume of air that can be inhaled from
the resting end-expiratory level (IRV + Vt)
(3600ml)
