Since more than a decade, the MicroScan has helped
physicians to easily monitor the microcirculation of their
patients at the bed side. It is a valuable tool for patient
and treatment monitoring throughout their stay at the
intensive care and even more so in situations of sepsis,

The MicroScan allows physicians valuable insight and
understanding in the most important organ in the
human body, being the smallest blood vessels. The
microcirculation occupies a vital position in between
the atrial and venous compartments, where nutrients
