ARTERIAL PRESSURE WAVEFORMS (pulmonary artery, arterial waveform) Pulmonary artery and arterial pressure waveforms have similar morphology. The pulmonary artery, like the PAWP, is subject to considerable respiratory and movement artifact.
In this case of torsion, the low-velocity arterial waveform displays ﬂow above (systole) and below the baseline (diastole), indicating increased resistance with reversed diastolic ﬂow. FIGURE 25. Two pregnant women with abnormal uterine artery waveforms.
The shape of the arterial waveform can provide information about myocardial contractility and hypovolaemia. Myocardial contractibility is indicated by the slope (dP/dt) of the arterial upstroke. A narrow waveform with a low dicrotic notch and a peak pressure that varies
waveform flattens; in critical limb ischaemia it may be undetectable. Examination of an arterial stenosis shows an increase in blood velocity through the area of narrowing.

The arterial waveform is clearly not a simple sine wave as described above, but it can be broken down into a series of many component sine waves. The arterial pressure wave consists of a fundamental wave (the pulse rate) and a series of harmonic waves.
