From: Beyond dichotomy: patterns and amplitudes of SSEPs and neurological outcomes after cardiac arrest
a Amplitudes of the N20–P25 component according to Cerebral Performance Category (CPC). Two patients in the CPC 3 group and 3 patients in the CPC 5 group had an amplitude above the upper limit for CPC 4 (> 2.31 μV). b Y-axis restricted to low amplitudes. The lower limit for CPC 1 and 2 was N20–P25 amplitudes > 0.64 μV
