Fig. (8) The three global PDMs of the two-input CFA model for each of the two inputs, MABP (left column) and ETCO2 (right column), shown in the time-domain (top panels) and in the frequency-domain (bottom panels). The values of the integrated PDMs (areas): are 0.0342, 0.2682, 1.4483 for MABP and 1.4288, 3.8415, and 0.8285 for ETCO2 (1^st, 2^nd and 3^rd respectively).
