SESSION TITLE: Sleep Disorders I

SESSION TYPE: Original Investigation Poster

PRESENTED ON: Saturday, April 16, 2016 at 11:45 AM - 12:45 PM

PURPOSE: To evaluate the clinical value of transcutaneous CO2 (TcPCO2) measurement in sleep respiratory monitoring

METHODS: Twenty nine patients (49.5±12.9) years old, Body mass index (BMI) (28.2±3.6) kg/m2) were prospectively recruited for the study. All of them underwent polysomnography (PSG) at the Sleep Center, Peking University People’s Hospital between January to August 2013. TcPCO2 signal was input to PSG systems, and TcPCO2 (TCM4, Radiometer, Demark) were measured simultaneously. Arterial blood gases (ABG) analysis for arterial pressure of CO2 (PaCO2) were undertaken to validate TcPCO2 measurement and statistically analyzed by Pearson's product-moment correlation. Dynamic change of TcPCO2 was monitored in rapid eye movement (REM) and non-rapid eye movement (NREM) sleep stages. Noninvasive positive airway pressure ventilation (NPPV) treatment effect on TcPCO2 during sleep was also observed.
