Proper IABP Timing
Timing refers to the positioning
of inflate and deflate points on
the arterial pressure waveform.
Inflation
•
Occurs at the dicrotic notch
•
Appears as a sharp “V”
•
Ideally diastolic augmentation rises
above systole
Deflation
•
Occurs just prior to systolic ejection
•
Results in a reduction in assisted
end diastolic pressure
•
Results in a reduction in assisted
systolic pressure
