Fig. 6. Logistic regression analysis curves relating specific indicator values of anesthetic concentration (scaled as log10)( A ), Pwr40-Hz38 ms( B ), and LatNbto probability of nonresponse to command during desflurane and propofol ( C ). The range of Pwr40-Hz38 msvalues corresponds to ranges for desflurane of 1.0–6.0 vol% and for propofol of 0.7–7.0 μg/ml. The range of LatNbvalues corresponds to ranges for desflurane of 1.0–6.0 vol% and for propofol of 1.0–10.0 μg/ml.
