- 15-year-old Lewis Blackman underwent elective surgery for pectus excavatum (sunken chest) at an academic medical center.
- In the days following surgery, Lewis experienced worsening abdominal pain but nurses dismissed it as constipation and insisted he walk more.
- His condition deteriorated over several hours but nurses were busy preparing for an inspection and did not take his worsening vital signs seriously.
- It was not until Lewis said "It's going black" that a cardiac code was called, but he could not be resuscitated and died 31 hours after reporting the abdominal pain.
