What Is the SphygmoCor XCEL System?

The SphygmoCor XCEL is a non-invasive cardiovascular measurement system that measures central and brachial blood pressures, assesses vascular biomarkers, and provides clinicians and researchers with a comprehensive picture of arterial stiffness and health. These advanced physiological measurements support early detection of potential cardiovascular issues and can guide targeted interventions to maintain or improve overall cardiovascular health.

The system operates in two functional modes:

Pulse Wave Analysis (PWA)

PWA analyzes the characteristics of the arterial pulse waveform to provide insights beyond traditional blood pressure measurement, including arterial wall elasticity and compliance. These measurements offer a more comprehensive understanding of vascular health and can aid in the early detection of cardiovascular risk. PWA is widely used in cardiovascular research to investigate the impact of interventions, medications, and disease states on arterial function.

Pulse Wave Velocity (PWV)

PWV measures the speed at which the arterial pulse travels through the vessel wall between two defined points, typically along the aortic segment from the carotid to the femoral artery. Stiffer arteries transmit the pulse wave more rapidly; therefore, an elevated PWV value serves as a key indicator of arterial stiffness and an independent predictor of adverse cardiovascular events. Monitoring PWV is instrumental for assessing vascular aging and guiding interventions to preserve or improve cardiovascular health.
