SphygmoCor Technology
The SphygmoCor family of products provides tools for
non-invasive assessment of the cardiovascular system and
autonomic function. The technology that powers these
products is centred on a transfer function that derives
the pressure wave at the ascending aorta. The transfer
function is a patented mathematical model of the
properties of the brachial artery and provides important
central data through a non-invasive recording of the
pressure wave at the radial artery. SphygmoCor allows
the physician to see the cardiovascular state of the
patient, where it really matters – at the heart. The SphygmoCor family includes:
SphygmoCor Px Aortic BP Waveform Analysis System This non-invasive doctor’s office device takes a
10-second snapshot of the radial arterial pressure wave
and derives the ascending aortic pressure wave,
providing critical cardiovascular measurements including
aortic Augmentation Index, Ejection Duration and
Subendocardial Viability Ratio. The system may
facilitate early identification of cardiovascular risk,
and is essential for the management of patients with
hypertension, diabetes, diastolic heart failure, and
other high cardiovascular risk conditions such as renal
disease and hypercholesterolaemia.
SphygmoCor Vx Pulse Wave Velocity System The Vx system enables the measurement of the velocity of
the pressure wave along a specific arterial segment. The
velocity of the pressure wave along the artery is
dependent upon the stiffness of the artery. This system
is most commonly used to measure the aortic pulse wave
velocity, by taking a reading at the carotid artery and
the femoral artery. Aortic pulse wave velocity typically
doubles between the ages of 30 and 60.
SphygmoCor Mx Aortic BP Monitoring System The Mx system provides a continuous real-time derivation
of the aortic pressure wave and key cardiovascular
parameters, allowing beat-to-beat monitoring of the
definitive blood pressure of the patient. The system is
ideally suited for anaesthesiology, and intensive care
environments.
Heart Rate Variability System The HRV System provides a simple measure of autonomic
function. The system allows analysis of both time and
frequency domains, and measures of sympathetic and
parasympathetic activity. The system allows valsalva and
standing manoeuvre tests to be performed.
