The role of overnight pulse-oximetry in recognition of obstructive sleep apnea syndrome in morbidly obese and non obese patients.

Abstract

Assessment of the Desaturation Index by nocturnal pulse-oximetry maintains its utility as a screening method for OSAS in both obese and non-obese patients with high clinical pre-test suspicion, despite the fact that the basal nocturnal saturation was found to be lower in group A.
