The same gold-standard, now remastered.

NIRS made easy

NIRS device

The PortaMon is a wireless NIRS device that is specially designed for muscle research. It uses a Bluetooth connection, which even enables you to record online while the subject is on e.g. a running track. For larger distances, the PortaMon can also store its data locally, ready for downloading afterward.

The PortaMon is mainly used for sports science (Buchheit 2011, Hesford 2012, Jones 2013) but is also applicable for other areas such as rehabilitation (Wang 2012*, Gayda 2014*), mitochondrial function (Ryan 2012*), and even for urology research (Macnab 2008).

A recent review by Perrey et al. (2024) provides an updated look at how NIRS can measure muscle oxygenation non-invasively.

PortaMon applications

The PortaMon offers the same possibilities that the larger NIRS devices give you. Next to the standard concentration changes of oxy-, deoxy- and total hemoglobin, this device also provides a value of tissue saturation: the percentage of oxygenated hemoglobin. The PortaMon uses a Bluetooth connection, which even enables you to record online while the subject is, eg. running on a track. For larger distances the PortaMon can also store its data internally, ready to be downloaded afterward. A third possibility is to store data in our purpose-built Android app. All publications with the PortaMon can be found on our publications page.

The near infrared spectroscopy technique

How it works

Optical oximetry and near-infrared spectroscopy (NIRS) in particular a tool for assessing the oxygenation status and hemodynamics of various organs, e.g. muscle and brain non-invasively. It relies mainly on two characteristics of human tissue. Firstly, the relative transparency of tissue for light in the NIR range, and secondly the oxygenation-dependent light absorbance of hemoglobin.

Marco Ferrari and Valentina Quaresima, NIRS and fNIRS pioneers at the University of L'Aquila, Italy.

“Artinis Medical Systems was founded in 2002 as a spin-off of Radboud University Nijmegen. At that time, a 12-channel fNIRS prototype built by Dr. Colier and co-workers at Radboud University enabled my group to be the first in Europe to collect real-time cortical oxygenation maps of cognitive and motor tasks.

With extensive knowledge of tissue optics and experience in solving biomedical challenges, the people at Artinis have been developing top-quality fNIRS instruments and oximeters–including wearable and wireless devices– for over a decade. We can attest that their technical and scientific support is unbeatable.”
