Answer

Findings in status asthmaticus with often imminent respiratory arrest include the following:

  • Paradoxical thoracoabdominal movement

  • Wheezing may be absent (in patients with the most severe airway obstruction)

  • Severe hypoxemia may manifest as bradycardia

  • Pulsus paradoxus may disappear; this finding suggests respiratory muscle fatigue
