Fast flush test arterial line

When you squeeze the fast flush valve, you let the transducer taste some of the 300mmHg in the pressurized saline bag. This produces a waveform that rises sharply, plateaus, and drops off sharply when the flush valve is released again. This is the "square wave". After the fast flush has ended, the transducer … See more The over-damped trace will lose its dicrotic notch, and there won't be more than one oscillation. This happens when there is clot in the catheter tip, or an air bubble in the tubing. The higher frequency components of the … See more The under-damped trace will overestimate the systolic, and there will be many post-flush oscillations. The MAP remains the same in spite of … See more WebArterial Line Damping. The dynamic response of an arterial line system is tested using the "fast flush" test, where the transducer is briefly exposed to pressure straight from the counterpressure bag. When the fast flush abruptly ends, the transducer system oscillates at its natural frequency. This can be measured and assessed for adequacy.
