Question

D: Frank has a relatively sudden onset of Guillain-Barre syndrome, a neurological disease that can, as in Frank's case, impair diaphragmatic and intercostal muscle function, and hence the ability to move air in and out of the lungs. The disease creates a number of problems for its victims, but we will concentrate on Frank's respiratory problems. If there are no other problems (airways, lungs, chest wall, respiratory effort, changes in respiratory rate) Questions 61-64 concern the following elaboration of Scenario D Scenario E: Suppose that Frank changes his respiratory frequency (but not tidal volume) so that his minute volume returns to the value before the onset of the disease. 61. How would this affect intrapleural pressure - compared to Scenario D? a) significantly increased (less negative) b) largely unchanged c) significantly decreased (more negative) 62. How would you expect this to affect Frank's alveolar PO2 - compared to Scenario D? a) increased back to normal b) increased beyond normal c) increased but not back to normal d) largely unchanged e) decreased significantly 63. How would this affect O2 delivery to the systemic tissues - compared to Scenario D? a) increased back to normal b) increased beyond normal c) increased but not back to normal d) largely unchanged e) decreased significantly 64. How would this affect CO2 elimination - compared to Scenario D? a) increased back to normal b) increased beyond normal c) increased but not back to normal d) largely unchanged e) decreased significantly
