Wristband diagnoses sleep apnea at home

The indicators used to diagnose sleep apnea—heart and respiratory rates, stress, blood oxygen level—can now be measured at home with a simple wristband. Leti showcased the innovative device at CES 2018 and is working with manufacturing partners to get the product out to medical professionals. The complete solution includes the wristband (with optical and electrical sensors) and data interpretation software. The results are saved to memory and sent to the patient’s doctor via a smartphone or PC. A preliminary study of 60 patients conducted in conjunction with Grenoble University Medical Center and INSERM demonstrated that 90% of significant respiratory events could be detected by the bracelet—sufficient for a preliminary sleep apnea diagnosis.
