Cardi/Check evaluates acute and chronic stress through the vital rhythmic balance by means of five indicators: the Cardiflex, the Cardistress, the ANS, the cardiac coherence and the RTI.



CardiFlex assesses the cardiac coherence (variability between two heart beats).

The algorithms used for the Cardiflex are based on two points of the pulse wave: systole and reflexion. They estimate the arterial flexibility.

CardiStress shows the stress index and the physiological ability to resist stress. This estimation is based on the activity of the cardiac coherence and the ANS.

+ ANS (Autonomie nervous system)
The ANS represents the balance between the sympathetic and the parasympathetic nervous system.

+ RTI (Respiratoire issue index)
The RTI is an evaluation of the blood oxygen saturation.


The Cardi/Check is based an assessments performed by a pulse oximeter. Oximetry is an analysis method
based on the evaluation of light the absorption of hemoglobin.

The Cardi/Check uses the oximetry



The oximetry

Pulse oximetry continuously analyses the quantity of oxygen circulation in the artères.  This is called arterial hemoglobine saturation (the molécule transportant oxygen to the tissues). When hemoglobin is transporting oxygen, it is called “oxygen-sutured” hemoglobin.
It is used to measure the the cardiac rhythm and the quantity of oxygen transported by the blood.
Benefit: this assessment is non-invasive because it involves no injection or blood extraction.

How does it work?


The Cardi/Check is a reliable and scientifically provin device.
The results are based on our algorithme which in turn are based on physiological mesures approuves by the scientific community.

✔ the physiological data is entered
​✔ the index finger is inserted in the oximeter
​✔ the data is processed and analysed
​✔ the data is sent to and saved on a secured server which enables a follow-up care
✔ the results can be consulted on your computer
