After suffering from sleep apnea for years, doctor Diego Delía decided to find a solution. He then developed an invention that treats the decrease of oxygen in the blood, called hypoxia, which is generated by sleep apneas. The small wearable for fingers can detect a significant reduction of oxygen in the blood and then release a tiny stimulus, that makes the person suffering from this disorder to change position and thus end the apnea. The wearable is capable of improving the quality of sleep for the millions of people around the world who suffer from this disorder. Obstructive Sleep Apnea consists of a repeated cessation of breathing during sleep due to the closure of the airways and is the most common sleep disorder according to the World Association of Sleep Medicine: it represents 80% of cases and affects 4 of every 100 men and 2 out of 100 women between 30 and 65 years of age. Lastly, it can be used to diagnose silent hypoxia in COVID19 patients.
