A 35-year-old man with no significant
medical history was scuba diving in moderate-depth water. He had a
generalized tonic-clonic seizure and then stopped breathing.
Resuscitation efforts were started. The patient was intubated on his
way to the hospital. On arrival in the emergency department, the
patient was not responsive. Both pupils were dilated with no
response to light, the BP was 60/20 mm Hg, the heart rate was 110
beats/min, and a chest radiograph was obtained (Fig 1). Mechanical ventilatory support and
cardiopulmonary resuscitation were started. Despite extensive efforts,
he had a cardiopulmonary arrest and was pronounced dead.
