Characteristric CVP findings: classically, a sawtooth "M" or "W" configuration of a raised CVP. Chapter 18 (Pericardial Constriction and Cardiac Tamponade, p.313 ) from Jonathan Marks' Atlas of Cardiovascular Monitoring (1993) has an entire section on the CVP trace in cardiac tamponade. The waveform patterns below were abducted from Marks and ...

Cardiac tamponade is a recognized early or delayed complication in open cardiac surgery, such as in 0.2% of coronary artery bypass grafting (CABG) and 8.4% of heart transplants, compromising ...
Pericardial tamponade - EMCrit Project

Central venous pressure (CVP) versus pericardial pressure ... Examine the arterial line tracing over several respiratory cycles. This is the most accurate way to measure the pulsus. ... The key management of tamponade is drainage of the effusion – and that should be the priority. However, in some situations it may not be possible to ...
Ultrasound Zoom: On Cardiac Tamponade | FCEP
https://fcep.org/ultrasound-zoom-on-cardiac-tamponade/
Cardiac tamponade is a syndrome that results from the compression of the heart by a pericardial effusion, which impedes normal cardiac function and results in hemodynamic compromise and obstructive shock. ... The normal flow pattern in the hepatic veins closely resembles a CVP tracing with three waves: a small retrograde A wave, followed by ...

Pericardial tamponade | Critical Care Medicine - McGill ...
https://www.mcgill.ca/criticalcare/teaching/files/pericardial-tamponade
Pericardial tamponade. Definition = a condition in which the pressure in the pericardial space is increased, resulting in hemodynamic abnormalities that reflect compression of the chambers of the heart. Hemodynamic abnormalities due to compression of the heart constitute a spectrum. Compromise of the circulation represents an advanced degree.

CVP tracing in tamponade • V wave: » Passive filling of the RA during RV systole • Y descent: » TV opens, passive RA emptying ... » Passive emptying of RA is dependent on pressure difference between RA and RV: in tamponade, the pericardial pressure takes over all other diastolic pressures (= loss of Y descent) Cardiac tamponade: echo ...
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 immediately follows the p wave of the ECG waveform. The a-wave is a pressure increase that is due to atrial ...
RA/CVP Waveform Interpretation - RK.md

RA/CVP Waveform Interpretation. By Rishi. February 12, 2020. 16. 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 ...

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.
