n.
The gradual reduction of excessive oscillation, vibration, or signal intensity, and therefore of instability in a mechanical or electrical device, by a substance or some aspect of the device.

damping

(ˈdæmpɪŋ)
n
1. moistening or wetting
2. stifling, as of spirits
3. (Electronics) electronics the introduction of resistance into a resonant circuit with the result that the sharpness of response at the peak of a frequency is reduced
4. (General Engineering) engineering any method of dispersing energy in a vibrating system

Underdamping is caused by resonance in the system, which can be controlled by a propriety device inserted between the arterial catheter and the transducer.
A number of factors are thought to contribute to suboptimal damping; air bubbles within the tubing system dramatically increase the CoD, as do blood clots--both resulting in overdamping, while excessive lengths of tubing reduce the CoD, resulting in underdamping.
Firstly, although over- or underdamping affects mean arterial pressure (MAP) minimally, it leads to large inaccuracies in measurements of systolic and diastolic blood pressure, [7] both of which are key measured variables used to direct therapy, especially fluid resuscitation.
