Figure 2. The time interval associated with the most emboli in each of 25 patients. The greatest number of emboli were apparent either after skin incision or > 3 min after the aortic clamp was released. Two patients are counted twice on this graph because they had a maximal number of emboli at two times. In one of these two patients, the maximal count was one embolus; in the other patient, the maximal count was 13 emboli. See the legend for Figure 1for definitions of the time intervals.
