Question	Answer
Fick's law in relation to gas exchange	Gas diffuses at a rate directly proportional to tissue area and the pressure gradient of the gases on both sides of the membrane
tidal volume	air volume moved during either the inspiratory or expiratory phase of breathing cycle
inspiratory reserve volume	reserve ability for inspiration
expiratory reserve volume	the amount of air left when subject exhales, then continues to exhale and force out additional air
forced vital capacity	total volume of air voluntarily moved in one breath
residual lung volume	air volume remaining in lungs after exhaling as deeply as possible
total lung capacity (TLC)	= RLV(residual lung volume) + FVC(forced vital capacity)
helium dilution method	way to indirectly measure RLV; subject exhales normally then rebreathes a known helium mixture for 5 mins
oxygen dilution method	more rapid assessment of RLV than helium dilution; determines RLV from dilution of lung's original nitrogen concentration, achieved by rapidly rebreathing a volume of 5 L of 100% oxygen
maximum voluntary ventilation	evaluates ventilatory capacity with rapid and deep breathing for 15 secs.
minute ventilation	volume of air breathed each minute; MINUTE VENTILATION = BREATHING RATE X TIDAL VOLUME
ventilation-perfusion ratio	a ratio signifying that alveolar ventilation matches each liter of pulmonary blood flow
dyspnea	inordinate shortness of breath or subjective distress in breathing
Valsalva maneuver	forced exhalation against a closed glottis; can cause an acute drop in BP
