Published	01/14/2024	The sum of the tidal volume plus the inspiratory reserve volume is known as {{c1::inspiratory capacity}}
Published	01/14/2024	The sum of the residual volume plus the expiratory reserve volume is known as {{c1::functional residual capacity}}
Published	01/14/2024	The volume of gas remaining in the lungs after normal expiration is the {{c1::functional residual capacity}}
Published	01/14/2024	The sum of the tidal volume, inspiratory reserve volume, and expiratory reserve volume is known as the {{c1::vital capacity}}
Published	01/14/2024	The maximum volume of gas that can be expired after maximal inspiration is known as the {{c1::(forced) vital capacity}}
Published	01/14/2024	The sum of the tidal volume, inspiratory reserve volume, expiratory reserve volume, and residual volume is known as the {{c1::total lung capacity}}

Published	01/14/2024	Functional residual capacity may be measured using {{c1::helium dilution}} or {{c2::body plethysmograph}}
Published	01/14/2024	What is the typical normal value for anatomic dead space (mL)?{{c1::150 mL}}
Published	01/14/2024	The volume of the {{c2::anatomic}} dead space plus the {{c2::alveolar}} dead space comprises the "{{c1::physiologic}} dead space"
Published	01/14/2024	The {{c1::apex}} of a healthy lung is the largest contributor of alveolar dead space
Published	01/14/2024	{{c1::Physiologic dead space}} is the total volume of the lungs that does not participate in gas exchange
Published	01/14/2024	In healthy lungs, the physiologic dead space is approximately equal to the {{c1::anatomic dead space}}
Published	01/14/2024	In certain pathologic situations, the physiologic dead space may become greater than the anatomic dead space, suggesting a(n) {{c1::ventilation/p…
Published	01/14/2024	Pathologic dead space is when part of the respiratory zone is {{c1::ventilated::perfused/ventilated}}, but not {{c1::perfused::perfused/ventilated}}&n…
Published	01/14/2024	What equation may be used to determine the physiologic dead space (VD)?{{c1::}}
Published	01/14/2024	{{c1::Minute}} ventilation is the total volume of gas that enters the lungs per unit time
Published	01/14/2024	{{c1::Alveolar}} ventilation is the volume of gas per unit time that reaches the alveoli (accounts for physiologic dead space)
Published	01/14/2024	What equation may be used to calculate minute ventilation? Minute Ventilation (VE) = {{c1::VT * Respiratory Rate}}
Published	01/14/2024	What equation may be used to calculate alveolar ventilation? Alveolar Ventilation (VA) = {{c1::(VT - VD) * Respiratory Rate}}
Published	01/14/2024	What is the normal range of respiratory rates for a healthy adult (breaths/min)? {{c1::12-20 breaths/min}}
Published	01/14/2024	If CO2 production is constant, then the arterial and alveolar {{c2::Pco2}} is determined by {{c1::alveolar ventilation}}
Published	01/14/2024	What is the effect of increased alveolar ventilation on arteriolar (and alveolar) Pco2?{{c1::Decreased Pco2}}
Published	01/14/2024	What is the effect of decreased alveolar ventilation on arteriolar (and alveolar) Pco2?{{c1::Increased Pco2}}
Published	01/14/2024	The alveolar gas equation states that the alveolar Po2 (PAo2) equals:{{c1::}}
Published	01/14/2024	When using the alveolar gas equation, the respiratory quotient (R) is equal to the ratio of {{c1::CO2 produced}} / {{c1::O2 consumed}}
