Towards the Automated Analysis and Database Development of Defibrillator Data from Cardiac Arrest

Table 8

Results for the comparison between manual and automatic recording of device operation and therapy variables for the data set. The table counts the number of correct and wrong values. For all variables except imp and enrgy an automatic recording is considered correct if the automatic recording is identical to the manual recording. Otherwise the recording is considered wrong. For imp and enrgy the numeric deviations between the manual and automatic recordings are considered. A deviation of zero is considered correct, and larger deviations are counted as errors.
