- Estimation of jugular venous pressure (JVP) is valuable for the differentiation between dyspnoea of cardiac or pulmonary origin, and for determining the cause of oedema.
- JVP assessments are useful for evaluation of treatment of right ventricular failure.
- The correlation between non-invasive JVP and invasive measurement of the central venous pressure (CVP) is remarkably better than previously reported. Correlation between JVP - determined via the external jugular vein - and CVP is excellent when the outcomes are categorised into low, normal and elevated pressure.
- Optimal measurement configurations include: extended expiration (without Valsalva manoeuvre), and during ventricular diastole. In the literature, these measurement configurations concerning the respiratory cycle and cardiac cycle have not been applied uniformly.
- To investigate in detail the correlation between JVP and CVP, the methods need to be standardized, and tests performed simultaneously and correctly.
