Peripheral (radial) and aortic arterial blood pressure waveforms from 2 sample patients. Whilst “Jan” (solid line) and “Joe” (dashed line) both have a systolic/diastolic blood pressure in the arm of 140/80 mm Hg, the aortic blood pressure magnitude is markedly different, with “Joe” having a blood pressure of 136/80 mm Hg and “Jan” having a blood pressure of 115/82 mm Hg. This difference in magnitude is relayed in the waveform shape of the peripheral waveform.
