Blood pressure responsiveness to obstructive events during sleep after chronic CPAP

2003

The aim of this study was to investigate whether chronic continuous positive airway pressure (CPAP) affects blood pressure (BP) responsiveness to obstructive events occurring on the first night of CPAP withdrawal in obstructive sleep apnoea (OSA) after chronic treatment. Thirteen male subjects with severe OSA underwent nocturnal polysomnography with beat­by­beat BP monitoring before treatment and after 4.9±3.4 months of home CPAP (mean daily use 5.1±1.7 h). Variations in oxyhaemoglobin saturation (Δ S a,O2), systolic (Δ P s), and diastolic (Δ P d) BP within nonrapid eye movement apnoeas and hypopnoeas were measured on a sample of pre­ and post­treatment events. In addition, a pretreatment s…
