Detection of sleep apnea with the forced oscillation technique compared to three standard polysomnographic signals.

BACKGROUND The forced oscillation technique (FOT) allows analysis of the upper airway impedance and, hence, detection of obstructive sleep apnea. OBJECTIVE To evaluate FOT with respect to sensitivity and to specificity in online detection of sleep-disordered breathing patterns and to compare algorithmic onset detection time with manual onset time markers… CONTINUE READING
