Abstract

BACKGROUND: Standard polysomnography is generally used in the diagnosis of sleep apnea syndrome. However, this technique is laborious, costly and inconvenient as a screening test or a test for epidemiological study. A simple screening test for sleep apnea, administered at home, would provide physicians with a convenient and less costly means of evaluating possible sleep apnea.
OBJECTIVES
The aim of this study was to evaluate the validity of portable sleep monitoring devices. The validity of measurements made by the portable sleep monitoring devices was assessed by comparing respiratory parameters obtained using the portable sleep monitoring devices with those obtained using standard polysomnography. MATERIALS AND METHOD: Eighteen patients were collected and divided into two groups. Direct comparison was made between data obtained by the portable monitoring devices(MESAM IV in group 1 and Edentec in group 2) and data simultaneously obtained by standard polysomnographic techniques.
RESULTS
In group 1, oxygen desaturation index(ODI) and heart variation index(HVI) in MESAM IV were significantly correlated with apnea index(AI) and respiratory disturbance index(RDI) in standard polysomnography. In group 2, AI and RDI in Edentec were significantly correlated with those in standard polysomnography.
CONCLUSIONS
The results of this study suggest that portable monitoring devices(MESAM IV and Edentec) may be useful in screening test of sleep apnea syndrome.
