A laryngeal mask airway manages the airway during which phase of anesthesia?
The book’s answer is:
Induction
(However, it can also be used during maintenance)
Where is the respiratory center located?
Both the medulla oblongata and pons
The pontine respiratory group includes the pneumotaxic center and apneustic center, which limit inhalation (pneumotaxic) and controls the intensity of breathing (apneustic)
The medulla holds the dorsal respiratory group and the ventral respiratory group, which control the muscular contractions for both inspiration and expiration. The ventral group is only active during forceful breathing. The dorsal group is the primary controller of the rate of respiration.
