Conox is a non-invasive depth of anaesthesia monitor designed to help the anaesthesiologist assess patient brain activity and to rapidly detect how certain drugs are affecting the patient


  • qCON index provides a rapid indication of the depth of anaesthesia of the patient
  • qCON index range 0-99
  • qNOX index is based on low and high frequency EEG in order to detect any changes related to surgical stimuli
  • qNOX range 0-99
  • Burst Suppression Rate (BSR) tange 0-99
  • Electromyogrphy index (EMG) range 0-99
  • Signal Quality Index (SQI) 0-99
  • Lead off detection Continuous
  • Sensors Impedance Check Yes
  • Display update rate 1s
  • Alarms for qCON index Visual and auditive
  • Total index update time 10 s
  • Indices trends 5, 30 and 60 min windows available
  • Technical Specifications – EEG acquisition
  • EEG sensitivity 44.6 nV
  • Noise <1 μVp-p (BW 70 Hz)
  • CMRR >100 dB
  • Input Impedance >1Mohm (@10 Hz)
  • Sampling Frequency 1024 samples/second , 24 bits/sample
  • Input signal range ±374 mV


Highly conductive sensor pads allow the Conox proprietary sensor to achieve accurate EEG readings for both qCON and qNOX index calculations.
