Brief summary

The 4 following scores have been proposed to detect OSA (Obstructive Sleep Apnea): DES-OSA, STOP-Bang, P-SAP, and OSA50. The aim of this study is to evaluate the optimal cutoff value of these four scores to detect specifically serve OSA patients with hypoxemia.

Interventions

DIAGNOSTIC_TESTDetermination of optimal cutoff values.

The results of the four scores will be compared with the results of the polysomnography (PSG). A statistical analysis will be performed to determine the optimal cutoff value of each of the four scores to detect severe OSA patient with hypoxemia.
