Research

Before introducing its solutions to the market, i-Virtual has tested, challenged and studied them to demonstrate their effectiveness, reliability and security.

Clinical trials completed

Caducy has been the subject of a first clinical trial on more than 1000 patients at the Nancy University Hospital.

The main objective of this first trial was to evaluate the concordance between the monitoring obtained by Caducy (Heart Rate and Respiratory Rate) in reference to the standard acquisition measurements.
