Figure 2. The relation between the mean diaphragm action potential conduction velocity determined using the dip (APCV^DIP) and cross-correlation (APCV^XC) methods during increasing levels of neuromuscular blockade as quantified by changes in the peak-to-peak amplitude (V1) of the first evoked compound muscle action potential. All values are given as the group mean with 95% confidence intervals. The notation “n =#” indicates the number of animals included in the calculation.
