| When a person using inhalants becomes hypercapnic and hypoxic by rebreathing from a closed bag, the effects of the inhalant are intensified. |
| Seizures are usually due to hypoxic encephalopathy, hemorrhage or cerebral infarction. |
| Such damage might emerge after cerebellar maldevelopment, or an earlier undetected hypoxic or ischemic event. |
| The patient became febrile, hypoxic, developed hemorrhagic pneumonia, and died. |
| Control tissues were free of significant autolysis and showed no signs of hypoxic or ischemic injury. |
| Subjects were studied at baseline and during hypoxic and hypercapnic rebreathing tests. |
