Artinis Medical Systems

Artinis is the pioneer of wearable & portable near-infrared spectroscopy (NIRS) devices to monitor local oxygenation of both brain & muscle tissue non-invasively.

What is NIRS?
Near-infrared spectroscopy (NIRS), the technique on which Artinis devices e.g., the Brite and PortaLite are based, relies mainly on two characteristics of human tissue. First, the relative transparency of tissue to light in the NIR range. And secondly, the oxygenation-dependent light-absorbing characteristics of hemoglobin. By using a number of different wavelengths, the relative changes in oxy,- and deoxyhemoglobin concentrations can be displayed continuously. Optical oximetry, and near-infrared spectroscopy in particular, is a tool for assessing the oxygenation status and hemodynamics of various organs, e.g. muscle and brain.
