Optical oximetry and near-infrared spectroscopy (NIRS), in particular, is a tool for assessing the oxygenation and hemodynamic status of various organs, e.g. muscle and brain non-invasively. It is mainly based on two characteristics of human tissue. First, the relative transparency of tissue to light in the NIR range, and second, the oxygenation-dependent light absorption of hemoglobin.

NIRS Device
The PortaLite is ideal for measurements in the brain during daily activities. The small, flexible probe is easy to attach and wire to the portable battery compartment. It is a highly portable device and is currently one of the smallest and most portable brain oxygenation monitoring devices on the market. Therefore, the PortaLite is used in a wide range of applications, for example functional studies, sport science and rehabilitation.
The system has three light sources and is therefore capable of measuring the tissue saturation index (TSI), which is an absolute measure of oxygenated hemoglobin. In addition, the PortaLite uses near-infrared spectroscopy (NIRS) to measure oxy, deoxy, and total hemoglobin concentrations at the capillary level. The PortaLite was used by our clients during dual tasking (Maidan 2015), to detect epileptic seizures (Jeppesen 2014) and to measure the effect of hypoxia during the ascent of the world's highest volcano (Burtscher and Koch 2015). All publications with PortaLite can be found on our publications page.
PortalLite Applications
The PortaLite is an easy-to-use, truly portable oxygenation monitoring device. With the PortaLite you can take online measurements using Bluetooth or offline measurements through on-board data collection. This makes it a perfect device for both laboratory and field measurements. It has a flexible sensor to adjust to the curvature of the head or smaller muscles like the intercostal or trapezius muscle to offer even more possibilities.
Before Portalite was developed, researchers took OxyMon to great heights to measure the effect of hypoxia (Rupp 2013) or zero gravity (Brümmer 2011) on the brain; with the introduction of our portable NIRS devices this can now be done much easier with the same data quality.
