Figure 2: Arterial tonometer. (a) An example of the arterial tonometer (SphygmoCor, AtCor Medical, Sydney, Australia). The monitor shows the noninvasive beat-by-beat analysis of the radial artery pulse wave using applanation tonometry in a patient. (b) In the present layout, the monitor shows the reconstructed aortic arterial pressure wave (left) from a peripheral site and the tonometry-derived values (right) (see text for details)
