During status asthmaticus, what does it mean when wheezing suddenly stops?

• A. Normal respiratory function
• B. Complete airway obstruction
• C. Partial relief
• D. Improvement with therapy

Answer: (B)

In status asthmaticus, wheezing comes from airflow through narrowed airways. If wheezing suddenly stops, that doesn’t mean the airways have opened up. It often indicates that airflow has fallen so low that little or no air is moving—a silent chest. This is a dangerous sign of near-complete airway obstruction and impending respiratory failure, not improvement. It prompts urgent management: secure the airway if needed, provide high-flow oxygen, continue or escalate bronchodilator therapy, give systemic steroids, monitor ventilation, and be ready for possible intubation. The other scenarios—normal function, partial relief, or improvement with therapy—would not correspond to a silent chest in the context of ongoing status asthmaticus.
