This study examined the diagnostic ability and difficulties of pulse oxymetry as a device to screen sleep respiratory disturbances.<BR>Seventy-one subjects participating in this study were examined in the hospital by all-night polysomnography (PSG) and a pulse oxymeter for possible sleep respiratory disturbances. The following three items were compared to estimate the diagnostic performance of the pulse oxymetry: the apnea hypopnea index (AHI), which is calculated from PSG results, representing the hourly figures of apnea and hypoventilation; the oxygen desaturation index (ODI), calculated from pulse oxymetry results, indicating the hourly figures of the change in oxygen saturation of blood; and CT90, the ratio between the minimum blood oxygen saturation and the period of time that blood oxygen saturation dropped below 90%.<BR>AHI strongly correlated with ODI. Based on AHT 20 as the positive standard, the sensitivity and the specificity of diagnostic performance were 83.7% and 95.5%, respectively, with 4% ODI greater than ten as the diagnostic index. These results suggest that pulse oxymetry is a useful screening procedure due to its superior diagnostic performance.
