An advanced technique
Caducy innovation is based on the combination of the most advanced techniques.
Photoplethysmography records the light rays reflected by oxygenated blood, which is transported in peripheral vessels. Due to a variation of the amount of oxygen with blood flow, there are modulations of reflected lights that occur. The collected periodic wave corresponds to the pulse wave, and the processing of this allows to deduce the instantaneous heart rate.
The respiratory rate is taken from the analysis of the movements of the chest cavity, which makes it possible to obtain a very precise and real-time value.
This tool is the result of 5 years of research and development. This is a precise and robust system. As a matter of fact, Caducy is composed of unique algorithms for stabilization, filtering and image processing developed by i-Virtual in order to make the system less sensitive to movements and fluctuations in lighting. Used by several physiology research laboratories, Caducy is the subject of a clinical study on more than 1000 patients at the University Hospital of Nancy.
