Respiratory distress could soon be diagnosed at home


​Researchers at CEA Tech have developed a "health patch" for sufferers of sleep apnea that could improve diagnosis and treatment. The patch was developed under the Carnot GPS R&D project.

In France some 2.5 million people suffer from sleep apnea. However, just 15% receive treatment, and for good reason. Sleep apnea is diagnosed during observation at a sleep clinic and is only accurate half the time. This means long waits for patients. Leti, a CEA Tech institute, has been working on a solution that could soon give physicians an easier way to diagnose and treat more patients.

The integrated system, which comes in the form of a patch (measuring 4 cm x 5 cm and just 3 mm thick), is much less invasive than the equipment used at sleep clinics. It includes sensors to measure blood oxygen levels, heart rate, and cardiac activity patterns. The compact, low-power patch is also flexible, for increased patient comfort. Various departments of CEA Tech institutes Leti (and Liten, a CEA Tech institute) contributed to the innovative system.

Leti developed the signal processing and analysis technology that monitors patient vital signs in real time and calculates a diagnostic score. The patch could ultimately be equipped with a CO2 sensor and could be used by sleep apnea patients for in-home health monitoring.
