a person has a resting tidal volume of .5L, anexpiratory reserve volume of 1 L, a residual volume of 1.5L and avital capacity of 5L. About 150ml of the tidal volume representsdead space and 350 ml represents alveolar ventilation. at the endof a normal expiration, 2500 ml of alveolar gas remains in thealveoli and airways (the function residual capacity) In thesubsequent inspiration, this volume is mixed with 359 ml ofinspirer air to give a total of 2850 ml.
a. what proportion of the original alveolar gasremains in the alveoli after this one breath?
b. why is this value important?
c. what proportion is left on renewed after anotherbreath?
