Abnormal central venous pressure waveform patterns

Note that the machine-reported CVP here is hilariously understated. Sure, 29 mmHg might seem like a high CVP, until you look at the scale on the venous pressure trace and realise that the systolic venous pressure is 75 mmHg. The tricuspid valve here was purely decorative, and served no useful function whatsoever.

After insertion, central venous pressure (CVP) waveform showed abnormal large a-c wave complex ( Figure 1 – marked with red arrow) and CV P value was in the range of 10-12 mm Hg. Such wave pattern may resemble a cannon “a” wave of CVP. [ 1, 2] Transesophageal echocardiography was done which demonstrated lower end of central venous ...

OVERVIEW. Central venous pressure (CVP) is the pressure recorded from the right atrium or superior vena cava and is representative of the filling pressure of the right side of the heart. CVP monitoring in the critically ill is established practice but the traditional belief that CVP reflects ventricular preload and predicts fluid responsiveness ...
CVP waveform: Components - OpenAnesthesia
https://www.openanesthesia.org/cvp_waveform_components/
A normal CVP waveform contains five components. These components include three peaks (a, c, v) and two descents (x, y). All of these components correspond to various aspects of the cardiac cycle. The first peak is the a-wave, which …

Normal CVP ranges from 5 to 10 cm H 2 O or 2 to 6 mm Hg. 1 Changes in preload status are reflected in CVP readings. Any condition that alters venous return, circulating blood volume, or cardiac performance may affect CVP. If circulating volume increases (such as with enhanced venous return to the heart from fluid overload, heart failure, and positive-pressure …

RA/CVP Waveform Interpretation. Central venous pressure (CVP) or right atrial pressure (RAP) waveform tracings can often times provide useful insight about a patient’s right ventricle (RV), tricuspid valve (TV), and overall cardiopulmonary status. The waveform morphology is easier to identify at slower heart rates and consists of three waves ...

Central venous pressure, which is a measure of pressure in the vena cava, can be used as an estimation of preload and right atrial pressure. Central venous pressure is often used as an assessment of hemodynamic status, particularly in the intensive care unit. The central venous pressure can be measured using a central venous catheter advanced via the internal …
Anaesthesia UK : The central venous pressure trace - FRCA
https://www.frca.co.uk/article.aspx?articleid=100036
This waveform is obtained from the tracing of a central venous line. A wave - due to atrial contraction. Absent in atrial fibrillation. Enlarged in tricuspid stenosis, pulmonary stenosis and pulmonary hypertension. C wave - due to bulging of tricuspid valve into the right atrium or possibly transmitted pulsations from the carotid artery.
