Evaluation of acute and chronic stress via the rhythmic balance


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 (Autonomic nerveux system)

The ANS represents the balance between the sympathetic and the parasympathetic nervous system.

RTI (Respiratory tissue 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.

Web application (compatible with Windows and Mac OS)

A connected system with a personalized and secure access

a complete and personalized assissent which will help you optimise the follow-up care and offer well-founded advice


Oligo/Check uses an optic technology called spectrophotometry


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.

Mode of operation

The Cardi/Check is a reliable and scientifically proven device.

The results are based on on our algorithms which in turn are based on physiological mesures approved by the scientific community.

the physiological data is entered

the index finger is inserted in the oximeter

the date is processed analyzed by the Cardi/Check app 

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
