1. If lung compliance decreases with advancing age, in the absence of other changes: a) the work of breathing would increase. b)the lungs would be easier to inflate. c) lung elastance would decrease d) airway resistance would increase during inspiration 12. Assume a normal female with a resting tidal volume of 400 mL, respiratory rate of 13 breaths/min, and dead space of 125 mL. When she exercises, which of the following scenarios would be most efficient for increasing her oxygen delivery to the lungs? a) increase respiratory rate to 20 breaths/min but no change in tidal volume b) increase tidal volume to 550 mL but no change in respiratory rate c) increase tidal volume to 500 mL and respiratory rate to 15 breaths/min
