Extraction of the jugular venous pulse and carotid profile using a cervical contact plethysmography system
The jugular venous pulse (JVP) is considered a reliable parameter for the assessment of central venous pressure (CVP). Here, the functionality of a cervical contact plethysmography system designed for non-invasive and operator-independent acquisition of the JVP signal, is shown. To validate the signal, it was recorded in supine and sitting positions, together with the reference Electrocardiography (ECG), on 26 healthy subjects. In the supine acquired signal, the characteristic JVP waves (a, c, v) and the negative deflections (x, y) are well recognizable. In the sitting recorded signal, the systolic peak b and the d incisura of the Common Carotid Artery (CCA) waveform are recognized. For each signal, we calculated the Fraction of the Cardiac Cycle (ccf) represented by the time intervals between the JVP peaks and the ECG peaks, in the form: ΔtaP, ΔtcR, ΔtxP, ΔtvT, Δtyv, Δtvx, and Δtxa. The same was done for the CCA waveform, in the form: ΔtbS, ΔtbT, Δtdb, ΔtdS, and ΔtdT. This system could mitigate risks and costs associated with central venous catheterization and its potential extends to applications in telemedicine, sports medicine, and space medicine.
