Is Extracorporeal Membrane Oxygenation More Than Just Salvage Therapy in Acute Life-Threatening Asthma?

A 46-year-old previously healthy woman presented with dyspnea, fatigue, and diarrhea. She had been experiencing these symptoms for > 1 year, but they had worsened in the few weeks prior to presentation. She had become progressively dyspneic on exertion and at rest and had increased the number of pillows she was sleeping on at night. She reported having episodes of nonbloody, watery diarrhea five to six times a day. The episodes were not associated with abdominal pain or recent travel and occurred even with fasting. Review of systems was positive for intermittent hot flashes, heart palpitations, and myalgias. She was premenopausal. She denied fever, weight loss, cough, hemoptysis, chest pain, or new edema. She had a pertinent medical history of gastritis, a nonspecific murmur since childhood, current tobacco use with a five pack-year history, and a family history of non-first-degree relatives having lung, breast, and colon cancer. She had not received medical care since moving from Brazil to the United States 4 years earlier.
