•
Inflation begins after the dicrotic notch (aortic valve closure).
•
Deflation ends just before the next arterial pressure waveform.
Note
The dicrotic notch is visible prior to the balloon inflation point.

Figure 4-28. medSim 30013 Simulated Early Balloon Deflation
•
Inflation begins at the dicrotic notch (aortic valve closure).
•
Deflation ends too soon, causing a large U-wave before the next arterial
waveform.
