OxyMon

The Oxymon Mk III is a user-friendly and flexible near infrared spectroscopy system. It measures oxy-, deoxy-, and total hemoglobin concentration changes, optionally absolute concentrations and tissue saturation index in both brain and muscle tissue.

As for the device, the fibers and the holders are separate items -
you can design your own configuration to fit your needs.

Multiple configurations - up to 100+ channels

The OxyMon is one of the most versatile NIRS systems on the market. We offer a wide range of fibers, holders and fit-for-purpose solutions to support you as best as possible and to make each offer customer specific. If your research requires a full topographic NIRS systems we deliver a set-up enabling you to measure 100+ brain channels simultaneously with real time visualisation. Research with multiple OxyMon systems could be very useful during hyperscanning or for measurements on e.g. the occipital cortex where you will get the most out of your research by measuring with many channels.
Furthermore, we offer short-separation and reference channels to distinguish superficial activity from brain activity.


Technique

All cells in all organs of the body have a constant but variable need for oxygen. However, he body stores for oxygen are minimal. A constant and adequate supply of oxygen to the tissues through circulation is essential. The OxyMon monitors a subject’s local tissue oxygenation non-invasively by utilising the technique of near infrared spectroscopy.

Near infrared spectroscopy, (NIRS), the technique on which the OxyMon is based, relies mainly on two characteristics of human tissue. Firstly, the relative transparency of tissue for light in the NIR range, and secondly on the oxygenation dependent light absorbance of hemoglobin. 


NIRS Applications

The Oxymon has been used in almost all thinkable fields of research. With the rise of our wireless products for exercise related protocols it is now mainly used for multichannel brain research and customised setups using special fibers, holders or wavelengths. We deliver a set-up enabling you to measure up to 112 brain channels simultaneously with real time visualisation. The Oxymon is compatible with MRI, EEG, EMG, TCD, TMS, tDSC, MEG and many other techniques.

Main applications

  • Brain oxygenation monitoring
  • Functional studies (fNIRS)
  • Brain computer interface (BCI)
  • Hyperscanning

OxyMon publications

The Oxymon has been used to e.g. study the aging brain (Mehagnoul-Schipper 2003, Song 2015, Tan 2015); the brain at high altitude (Rupp 2013, Subudhi 2008), dementia (Tak 2011, van Beek 2011), functional testing (Ferreri 2015, Kennedy 2012, Minati 2009)  and for brain computer interfacing (Herff 2014, Spyrou 2014).
