Performance assessment of commercial continuous-wave near-infrared spectroscopy devices for the international HEMOCOVID-19 clinical trial

ABSTRACT

HEMOCOVID-19 project spans four countries and eight hospitals to evaluate the microvascular and endothelial health of severe COVID-19 patients using near-infrared spectroscopy (NIRS) of the forearm muscle. In order to implement the project, we have developed protocols and tested ten commercial continuous-wave NIRS devices of the same model (PortaMon, Artinis, NL). They were characterized and compared for intra-And inter-device, inter-And intra-operator and temporal variability in solid phantoms and in vivo. © COPYRIGHT SPIE.
