Neal L. Benowitz, MD; April 2019
A woman who required oxygen at home via nasal cannula and used a continuous positive airway pressure (CPAP) machine at night was admitted for an exacerbation of chronic obstructive pulmonary disease without any signs of infection. During her hospital stay, she continued to require 5 liters of oxygen by nasal cannula. Although the patient had received smoking cessation education and no longer smoked regular cigarettes, she did continue to vape with an electronic cigarette (e-cigarette). Having not been told to avoid vaping in the hospital, the patient took a puff on her e-cigarette while she was receiving oxygen through her nasal cannula and sparked an explosion. She ripped off the nasal cannula, which had melted, and sustained burns to her face and hand, resulting in a prolonged hospitalization for burn care and extensive pain management.
