The clamp had been put in by the nurse to secure all the wires from the microscope along the bed and had inadvertently clamped our radial artery line. by arterial line and non-invasive cuff in critically ill children Rachel Joffe1 . Arterial line placement remains a readily acceptable . Inadequate damping will result in excessive resonance in the system and an overestimate of systolic pressure and an underestimate of diastolic pressure. causes of under damping arterial line 6. Arterial lines are connected to a bedside monitor to continuously display both the waveform and pressure from within the artery (Image 2). . Excessive damping causes loss of detail in the waveform . Methods After ethics approval and consent, we performed the flush test and stopcock test on AL (to determine over damping, under damping, and optimal . Over-dampened: Air bubbles, kinks, clots, spasms, stopcock closed/loose connections, or no volume or low pressure in pressure bag and tubing. Can you run fluids through an arterial line? 5 Arterial spasm. This typically gives us three results, which we can use to interpret what is going on with the arterial line. Bubbles cause overdamping, which doesn't affect MAP, so this is correct. Now its time to Zero this is the pressure relative to atmospheric pressure. A under damped trace will be hyper resonant and will over read any changes in the pressure. As blood continues into the peripheral vessels, arterial pressure falls, and the waveform begins a downward trend. Arterial line ,arterial BP ,central line, . Please enable scripts and reload this page. 2. prevent artery injury from multiple punctures. If unsure what is going on with waveform, complete a flush test and troubleshoot with your newfound knowledge. This can underestimate systolic pressure and/or overestimate diastolic pressure. doi: 10.7759/cureus.17610.

Unless a child keeps pumping a swing, its motion dies down because of damping. Both the flushing and the withdrawal of blood from the line was successful. Would you like email updates of new search results? The most common reason for an under-damped spiked arterial trace is soft tubing inserted to extend the arterial line.
