Introduction:

The Baveno classification depends on the integration of multicomponent such as symptoms, including the ESS, as well as cardiometabolic comorbidities in the assessment of OSAS.[1] It was introduced to overcome the clinical and prognostic limitations of the AHI as a sole index in OSAS severity, as the upper airway obstruction alone does not completely describe the pathophysiology of OSAS. [1]

 Aims of the study:

Analysis of the effect of the Baveno classification on the optimum CPAP titration pressure.

 Patients and methods:

A retrospective analysis of the records of sleep studies in two centres between 2018- 2021. Patients diagnosed with OSAS and recruited for CPAP titration were included. Based on the Baveno classification, the patients were categorized into four groups (A, B, C, and D).

 Results:

700 patients were analysed and 427 patients were finally included. A non-significant correlation was seen between the Epworth Sleepiness Scale (ESS), symptoms severity, end-organ impact, and Baveno?s classification with CPAP optimum titration pressure (p: 0.8, 0.4, 0.5, and 0.7, respectively).

Conclusion:

The multicomponent Baveno classification is not helpful as a predictor of optimum CPAP titration pressure.
