Figure 5From: Automatic detection of AutoPEEP during controlled mechanical ventilation End-Expiration Detection using Wavelet transform. This figure illustrates the detection of end-expirations based on respiratory flow signal: (top) respiratory flow curve obtained from a patient, (middle) signal in the level-2 detail band of the wavelet transform coefficients and the calculated detection threshold, (bottom) detection result, where 1s (peaks) represent end-expirations.Back to article page
