WebWaveform should rise sharply, plateau and drop off sharply when released (Figure 1). Inaccurate damping can lead to inappropriate treatment: Overdamping (defined as when the oscillations following the downstroke are sluggish and can underestimate systolic pressure or overestimate diastolic pressure).
