Snoring is just the tip of the iceberg of a much greater problem

Obstructive Sleep Apnea (OSA) is a chronic disease where patients pause in breathing during sleep due to a blockage of airflow at the throat level, most often with loud and frequent snoring followed by choking. In severe cases, this can occur hundreds of times a night.

It is an application that must be used together with the sensor to perform the Digital da Sleep Apnea Monitoring test.

Patients who are in the process of being diagnosed with Sleep Apnea, as well as patients being treated for apnea in order to monitor the evolution of the disease.

No, Biologix is a platform designed to monitor sleep apnea digitally. For treatment, contact a healthcare professional.

We diagnose sleep apnea based on oximetry. When patients pause breathing, which is the main characteristic of apnea events, their blood oxygen level drops. Our solution detects these drops, based on which it calculates ODI (oxygen desaturation index). Based on data from both our validation study for this solution and the sleep apnea literature, we established reference values to rate results as normal (no apnea), mild, moderate, or severe apnea.

Upon test completion, result are automatically available for the accredited center. Thus, as soon as they complete the test, patients should go to the accredited center to return the sensor and get their results.

The test result includes personal information, period during which the test was performed, conditions in the night of the test, questionnaire, and results for the Biologix test parameters (oximetry, heart rate, hand movements, and snoring).

Results are generated immediately after the completion of the test on the app.
