Diagnostic evaluation profiles of ECMO patients with death by neurologic criteria

ID	Age	Sex	ECMO Mode	Neuro Exam	Head CT	Apnea Test	EEG	TCD
1	51	M	VA	No reflexes	Severe cerebral edema with uncal herniation	+	Absent reactivity, low voltage, and absent physiologic patterns	Absent waveforms and pulsatile indices
2	41	F	VA	No reflexes	Diffuse ischemic injury and uncal herniation	Not Performed	Absent cerebral activity	Short systolic spikes
3	42	F	VA	No reflexes	Intraparenchymal hemorrhage	+	Not Performed	Posterior cerebral circulatory arrest
4	43	M	VV	No reflexes	Intraparenchymal and subarachnoid hemorrhages with midline shift	+	Suppressed cerebral activity with absent variability and reactivity	Not Performed
5	57	M	VV	No reflexes	Diffuse cerebral edema, cerebellar hemorrhage with tonsillar herniation	+	Extremely low voltage with no reactivity or spontaneous variability	Short systolic spikes
6	48	M	VV	No reflexes	Intraparenchymal hemorrhage with uncal herniation	+	Not Performed	Not Performed
7	42	M	VA	No reflexes	Diffuse cerebral edema with brainstem compression	Not Performed	Absent cerebral activity	Not Performed
8	45*	M	VV	No reflexes	Intraparenchymal hemorrhage	+	Not Performed	Anterior and posterior cerebral circulatory arrest with short systolic spikes

^+:Consistent with death by neurologic criteria. -: Not consistent with death by neurologic criteria
