Age

18 Years to 70 Years

Inclusion criteria

Inclusion criteria: patients with suspicion of Obstructive Sleep Apnea (OSA)

Design outcomes

Primary

Measure	Time frame
Degree of agreement between the new sensor (CID-102) with the reference measurement (RIP - Respiratory Inductance Plethysmography) in terms of detection of three different pattern of disturbed breathing (obstructive apnea, central apnea, mixed apnea) explored by analysis of correlation, sensitivity, and specificity.	—

Secondary

Measure	Time frame
Interrater variability of scoring of obstructive apneas, central apneas, and mixed apneas with the new sensor (CID-102) during sleep	—
