Most clinicians are familiar with the dicrotic notch seen in any typical arterial pressure waveform. The notch represents the nadir point that occurs immediately after the closure of the aortic valves and precedes the secondary dicrotic wave. The notch is frequently used as a marker for the end of the ventricular ejection … See more The changes in the arterial pressure waveforms in response to the intra-thoracic pressure fluctuations associated with mechanical ventilation have been used very extensively to assess the adequacy of … See more Invasive arterial pressure measurements have been undertaken for several decades in operating theatres and in intensive care units. Apart from … See more As explained in the previous section, the size of the pulsatile component of the arterial pressure waveform (either PP or the area under the … See more In addition to the primary SP peak and the dicrotic wave, several other smaller secondary waves are frequently evident in an arterial pressure trace (Fig. 8).
