Comparing in-lab full polysomnography for diagnosing sleep apnea in children to home sleep apnea tests (HSAT) with an online video attending technician

The main study aim was to compare the validity of children sleep apnea data obtained from standard polysomnography (PSG) to a home sleep apnea test (HSAT) accompanied by an attending online video technician. Our study population was comprised of 100 children, 54 boys and 46 girls, ages 3–11 (average age 5.2, SD 1.2) assigned randomly either to in-lab full PSG or to a HSAT with real-time, online technical support to rule out obstructive sleep apnea (OSA). A t test comparison did not yield significant differences between data obtained from the in-lab PSG and HSAT with real-time, online, technical support for any of the following measures: Apnea–Hypopnea Index, Oxygen desaturation Index, baseline O2, or minimum O2 parameters. However, a significant difference was found for time in bed and total sleep time, which was significantly longer in the HAST. Online HSAT can provide a safe, convenient and a reliable way to perform sleep studies in young children for diagnosing OSA in their familiar home environment.
