WebJul 4, 2024 · Damping and Arterial Lines. Jul 04, 22. Damping is the influence within a system that is a dissipation of energy during an oscillation. In other words, think of damping like a shock absorber. Imagine a patient presenting with altered mental status. All we know about the patient is they have a history of hypertension. WebMay 30, 2024 · What Is Damping In Arterial Line? The arterial waveform reflects the change in pressure over time, or dP/dt, and thus the slope of the upstroke reflects this. Generally speaking, the steeper the slope, the quicker the rise, the greater the dP/ dt, and the stronger the contractile forces appear.
