For animals with respiratory disease, sigh the patient every _______ minutes to reduce these issues of hypoventilation, atelectasis, and/or apnea.

• A. 2 to 3
• B. 5 to 10
• C. 15 to 20
• D. 30

Answer: (B)

Periodic sighing helps recruit alveoli that tend to collapse with shallow breathing, improving ventilation and gas exchange in animals with respiratory disease. By increasing the tidal volume briefly, sighs reopen closed airways and maintain functional residual capacity, reducing hypoventilation, atelectasis, and apnea. The best interval is a moderate, regular pace—every few minutes—so alveoli are recruited regularly without disturbing the patient’s normal breathing pattern or causing discomfort. If sighs are too frequent, they can provoke unwanted hyperventilation or fatigue; if they’re too infrequent, derecruitment and atelectasis can recur. A balanced, steady interval yields the most consistent improvement in oxygenation and ventilation.
