Association between nondipping pattern and EndoPAT signal in patients with mild obstructive sleep apnea

To compare vascular endothelial function between dipping (D) and nondipping (ND) patterns in patients with and without mild obstructive sleep apnea (OSA) using EndoPAT, a test of reactive hyperemia used to assess peripheral vascular endothelial function. The sample consisted of individuals of both genders between 18 and 65 years of age with a body mass index (BMI) of ≤35 kg/m2 and apnea/hypopnea index (AHI) of ≤15. The nondipping pattern was...
