Abstract
Clinical vignette: An 8-year-old boy presents to the pediatric ICU after two days of cough with increasing secretions. The patient is progressing to respiratory failure and requires noninvasive mechanical ventilation. His past medical history is remarkable for premature birth at 25 and 6/7 weeks gestational age, cerebral palsy, developmental delay, epilepsy, and gastrostomy tube dependence. His chest x-ray is remarkable for multifocal opacities that are consistent with atelectasis. A complete blood count reveals a wbc count of 9.2 with a normal differential, Hg of 11.7, and platelet count of 276,000. A respiratory viral panel from a nasal swab returns positive for rhinovirus. Additional patient history from the parents uncovers that he has been hospitalized three times over the course of the past 2 years with a similar presentation.
