When someone is having a suspicion of sleep apnea, a referral to sleep center for a sleep test is often advised. A sleep test can be done in the sleep center itself, or you will be decorated with a lot of wires and be sent home. You sleep at home and go back to the sleep center the next day. Afterwards the results of the sleep test will tell you if you have sleep apnea or not. 20% to 35% of these people were not diagnosed with sleep apnea after all. A waste of time and money.
A much easier way
DiagnOSAS developed a way to exclude this 20% to 35%. A much easier way to determine if someone is suffering from sleep apnea; the OSAsense. It consists of a validated online questionnaire and an overnight pulse oximetry. The data collected will be analyzed on the OSAsense platform and the results will be available almost directly after uploading.
The clinical trial is enrolling 50 patients (all adults, aged 18-75) suffering from type 1 and 2 diabetes or diabetes due to other courses. At this current stage the tattoo-sensor provides just one readout, but eventually the developers hope to have a continuous sensor that monitors glucose for the whole day.
How does it work?
The used pulse oximeter (see picture above) registers the hemoglobin saturation level in the blood. With the outcome of this measurement, combined with the outcome of the validated questionnaire, the OSAsense algorithm is able to identify sleep apnea with a sensitivity and specificity of ~100% and >70% respectively. When the OSAsense will be used before referring patients to hospital, patients with a low risk of sleep apnea do not have to undergo expensive (and inconvenient) testing and patients with a significant risk can be referred much quicker to undergo appropriate treatment. In the graphic below you can see the current standard of care in general practice and the innovative approach implementing OSAsense.
