The aepEX depth of anaesthesia monitoring system presents the start of a new era in patient monitoring. The conscious intraoperative awareness of pain, fear and complete helplessness is an extremely serious complication. It occurs at a frequency of between 0.1 and 0.2% and, in the worst case, leads to post-traumatic stress disorder (PTSD)¹. Whereas the depth of sleep is measured as the priority in conventional EEG measurements, the aepEX PLUS records the acoustic perceptual capacity (auditory evoked potentials). Human acoustic awareness has the highest priority within human senses with regard to alarm functions in the evolutionary history. The lack of acoustic awareness (measured by the aepEX PLUS) can therefore inferentially exclude any awareness.
