4-14 I know that there are two big bad timing errors – what are they, why
are they so bad, and how do I make sure I don’t make them?
The two big bad timing errors are early inflation and late deflation.
They both come from moving the timing knobs too far away from center.
4-15 What is early inflation?
Early inflation is just that – the inflation knob is turned too far to the left, and the inflation wave actually comes before the dicrotic notch. To the left of it. This means that the balloon is inflating before the aortic valve closes, pumping backwards into the LV, which is already having a hard time emptying itself…
More arrows. Here they’re pointing to the inflation wave, which is way out ahead of where it ought to be. (IP I guess stands for “inflation point”.) See where it says DN? That’s where the inflation wave should be. (Why?) Ack! I have to say, just looking at this wave is enough to give me chest tightness…
What is late deflation?
