Figure 83-9 Vigilance test data during anesthetic tasks with and without automated record-keeping. The range of data is shown for each of four taskcategories in electronic automated record-keeping (EARK) and manual record-keeping (MAN). Each box contains 50% of the data for that subgroup (upper limit of box is the 75th percentile; lower limit is the 25th percentile), whereas the maximum and minimum are shown by the upper and lower horizontal bars. The response latency during record-keeping was not significantly different between EARK and MAN. In both record-keeping groups, subjects had significantly slower responses when observing or adjusting the transesophageal echocardiogram (TEE), compared with recording, observing monitors, or adjusting intravenous lines (IVs). Subjects in both groups had faster response latency when observing the monitoring array, which contained a red light, compared with the other three tasks. *, P < .05; †, P < .05.
