2. Fig 1
Rate of microemboli detection during surgical interventions, perfusionist interventions, and baseline (see text for definitions). Perfusionist interventions resulted in a significantly higher rate of emboli production.

3. Fig 2
Proportion of total microemboli detected during each event. Drug injections and blood sampling (perfusionist interventions) resulted in a higher proportion of emboli than other events. (Aorta cann, Aorta decann = aortic cannulation and decannulation; CPB = cardiopulmonary bypass; Eject = start of cardiac ejection after cross-clamp removal; XCL = cross-clamp.)

4. Fig 3
Rate of microemboli detection during each surgical intervention. Initiation of cardiopulmonary bypass (CPB on) and start of cardiac ejection after cross-clamp removal (Eject) resulted in higher rates of emboli production than other surgical events. Other abbreviations are the same as in Figure 2.

5. Fig 4
Rate of microemboli detection during perfusionist interventions. Drug injection resulted in a higher rate of emboli production than blood sampling or any other period examined.
