Clinical Effect and pressure.

Optimally damped system. When the fast flush of the continuous flush system is activated and quickly released, a sharp upstroke termi- nates in a flat line at the maximal indicator on the monitor and hard copy. This is followed by an immediate

Square Wave Test and a quick return to baseline. The patient’s pressure waveform is also clearly defined with all components of the waveform, such as the dicrotic notch on an arterial waveform, clearly visible. Intervention: There is no adjustm
