Electroencephalogram samples from six different patients undergoing pharmacologically induced burst suppression as treatment for refractory status epilepticus. In each case burst suppression depth was controlled manually by nursing staff adjusting the rate of propofol anesthetic infusions, according to standard clinical practice. Bursts are highlighted in pink, while suppression periods are not highlighted. The approximate burst suppression probability (BSP) values for these examples, given as percentages (100% = complete suppression, 0% = no suppression) are (A) 68%, (B) 55%, (C) 83%, (D) 70%, (E) 39%. Only case (C) is within 5% of the clinical target value, which in all cases was 80%.
