Automated vs Manual Polysomnography Scoring in Adults With Obstructive Sleep Apnea

Overview

This prospective study aims to compare automated polysomnographic scoring with manual scoring in adult patients with Obstructive Sleep Apnea (OSA). The main objective is to evaluate the accuracy, reliability, and time efficiency of automated scoring algorithms compared to standard manual scoring performed by expert sleep specialists

Study Procedures 1. Pre-PSG Assessment: Demographic data, anthropometric measurements (weight, height, Body mass index (BMI), neck circumference), vital signs, comorbidities, and the STOP-BANG questionnaire are recorded. 2. Overnight PSG: Conducted in a sound-attenuated, temperaturecontrolled, well-prepared sleep lab using either SOMNOscreen plus (SOMNOmedics GmbH) or Alice® 6 Sleepware (Philips Respironics, PA, USA). Both systems acquire this channels montage: • EEG (six channels: F3, F4, C3, C4, O1, O2 referenced to ipsilateral mastoids) • EOG (two channels: left and right outer canthus) • Chin EMG (three channels) and anterior tibialis EMG (two channels, bilateral) • Airflow (oronasal thermistor + nasal pressure transducer cannula) • ECG (2 leads) • Body position sensor • Snoring microphone Respiratory inductive plethysmography (RIP) belts for thoracic and abdominal effort (two channels) • Pulse oximetry (SpO₂, one channel) via finger probe
