If a patient sustained an injury to the apneustic center in the lower pons area, in which of the following areas would you most expect the patient to exhibit problems?
a. Respiratory rate c. Respiratory rhythm
b. Triggering exhalation d. Depth of respiration
D
The apneustic center in the lower pons is thought to work with the pneumotaxic center to regulate the depth of inspiration. The pneumotaxic center in the pons is responsible for limiting inhalation and triggering exhalation. This response also facilitates control of the rate and pattern of respiration. The ventral respiratory group, located in the medulla, is responsible for inspiration and expiration during periods of increased ventilation.
