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
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.
CEA is a French government-funded technological research organisation in four main areas: low-carbon energies, defense and security, information technologies and health technologies. A prominent player in the European Research Area, it is involved in setting up collaborative projects with many partners around the world.
