Under- and overdamping of the arterial blood pressure waveform and fast-flush test. The figure illustrates the characteristic changes of the arterial blood pressure waveform in case of under- and overdamping and the corresponding fast-flush test. The red arterial blood pressure waveform represents a “normal,” non-distorted waveform with normal fast-flush test, whereas the blue arterial blood pressure waveforms represent an underdamped (upper part of the figure) or overdamped (lower part of the figure) arterial blood pressure waveform. PP, pulse pressure; SAP, systolic arterial pressure; DAP, diastolic arterial pressure
