NIRO-200NX Near infrared oxygenation monitor

C10448

null

The NIRO-200NX is a tissue oxygenation monitor that uses near infrared spectroscopy. The unit uses safe, low light to measure the Tissue Oxygenation Index (TOI), showing the oxygen saturation level, the Normalised Tissue Haemoglobin Index (nTHI), showing the percentage change in the amount of initial haemoglobin, as well as changes in concentration of oxygenated haemoglobin (ΔO2Hb), deoxygenated haemoglobin (ΔHHb), and total haemoglobin (ΔcHb), all in real time.

Features

  • Measure data simultaneously in two locations (two channels installed)
  • Measure concentration changes in oxygenated, deoxygenated and total haemoglobin
  • Easy operation by simply pressing the start button
  • Transfer numerical value data to a personal computer
  • Safety and high reliability
  • Compact and lightweight
    • Half the size of the previous NIRO-200, providing the same great performance while making it much easier to use with an emergency cart or in the operating theatre.
  • External monitor output
    • View data on an external monitor at the same time, useful for anaesthetists and perfusionists
  • Input of event marks from external devices
    • Ability to input event marks externally, useful for analyzing the results of pump control and for research purposes
  • Equipped with battery
    • Useful in case of power failure or during patient transfer after an operation
  • Past data retrievable
    • Data stored in the NIRO-200NX can be retrieved for purposes such as patient counselling or research.
  • Touch panel display
    • The machine can be operated by touching the screen.
  • Data storage to USB memory devices
    • Data may be saved to a USB memory device, useful for analyzing the results of pump control.

Applications

  • Monitoring brain oxygenation during heart surgery and other procedures
  • Patient monitoring in emergency rooms
  • Patient monitoring in ICUs, CCUs, and NICUs
  • Clinical studies related to oxygenation levels and blood metabolism in the brain
  • Studies of muscle tissue oxygenation for sports medicine, rehabilitation and similar applications
  • Can be used on emergency carts
  • Can be used on rescue helicopters
