What does a whip on an arterial line mean?
Resonance or whip causes falsely increased systolic readings and falsely decreased diastolic readings. It occurs when the system’s frequency of oscillation (i.e., heart rate) matches the system’s natural frequency of vibration causing whip in the signal.
What causes damping of arterial line waveform?
The over-damped arterial line waveform This happens when there is clot in the catheter tip, or an air bubble in the tubing. The higher frequency components of the complex wave which forms the pulse are damped to the point where they no longer contribute to the shape of the pulse waveform.
What is systolic upstroke?
Systolic upstroke: This is the ventricular ejection. Of the two forward pressure wave components, this part is generated by the fast-moving 10m/sec wave, and corresponds to the peak aortic blood flow acceleration at the opening of the aortic valve.
What is an Overdamped waveform?
An overdamped- appearing (often simply called damped) waveform can also be the result of aortic stenosis, vasodi- latation, or low cardiac output states such as cardiogenic shock, sepsis, or severe hypovolemia ( Figure 5). …
What is upstroke in pulse?
While the upstroke of the carotid pulse reflects the driving force and vessel compliance, the downstroke reflects the distensibility of vessels and the peripheral resistance. After the aortic pressure curve peaks, it begins a decline as ventricular ejection slows and blood continues to flow to the periphery.
What is damping and Ventricularization?
These artifactual pressure waveforms are often referred to as “damped” or “ventricularized.”1 When the pressure transmission is compromised from either a coronary stenosis surrounding the catheter tip, or the tip is not coaxially located but rather rests against the vessel wall, the aortic waveform may be distorted.
What is damping of a wave?
damped wave [¦dampt ‚wāv] (physics) A wave whose amplitude drops exponentially with distance because of energy losses which are proportional to the square of the amplitude. A wave in which the amplitudes of successive cycles progressively diminish at the source.
