Medtronic NIM-Response 2.0 Features

The Medtronic NIM-Response 2.0 is an Electromyography (EMG) Monitor. The NIM-Response 2.0 is a four-channel EMG Monitor that can be used for nerve monitoring during surgeries such as ENT and general surgery. The NIM-Response 2.0 can record Electromyographic (EMC) activity and can help the surgeon locate nerves that may be in the area where surgery is needed. The NIM system can provide audible and visual warnings if there are changes to the patient’s nervous system. The monitoring system offers various ports to connect a USB or mass storage device the collect the recordings. The Medtronic Electromyographic Monitor has a touchscreen that can display up to four different waveforms and peak-to-peak amplitude. Medtronic offers a variety of different Electromyographic (EMG) devices, another device would be the Medtronic NIM-Response 3.0.

  • 4-channel EMG monitor that is individually and simultaneously selectable.
  • High contrast digital color touch display.
  • Increased sensitivity with reduced interference.
  • Printable log of patient’s EMG activity.
  • More sensitive to lower-level EMG activity with the improved signal-to-noise ratio.
  • Quick setup.
