The answer is A. This a favorite question of Dr. Yaster. The halogenated agents (halothane, sevoflurane, isoflurane and desflurane) all depress the ventilatory drive and responsiveness to carbon dioxide in a dose dependent fashion. This is mainly done through a DECREASE IN TIDAL VOLUME. Respiratory rates tend to increase up to 1 MAC and then decrease at levels above 1 MAC. Decreased airway tone is an effect, but usually causes obstruction, not decreased alveolar ventilation. | The answer is A. This a favorite question of Dr. Yaster.
