Sponsor's own description

Determination of changes in molecular breath patterns in OSA patients, naïve for OSA treatment before and after one month of CPAP therapy by untargeted, secondary electrospray ionisation-high resolution mass spectrometry (SESI-HRMS). Furthermore, breath patterns will be assessed for correlation and association to clinical outcomes such as change in OSA severity, sleepiness, and blood pressure.
