Two versions of the
XCEL are available:
SphygmoCor XCEL PWA
The SphygmoCor XCEL PWA device provides measurement Central
Aortic Blood Pressure and Augmentation index in 60 seconds. A brachial pressure
cuff is placed on the patients arm, over the brachial artery. The SphygmoCor
XCEL, with the press of just one button, takes the patients brachial systolic
and diastolic pressure, and then captures the patient’s brachial waveform. The
brachial waveform is then analyzed by the SphygmoCor Brachial GTF to provide a
Central aortic waveform, and Central Blood pressure measurements such as
Central Aortic Systolic BP, Central Pulse pressure and Augmentation index are
also displayed.
The
Patient’s measurement is displayed in relation to reference values based on the
patients’ age and sex. So in this case the patient’s central Pulse pressure
(PP), Augmented Pressure (AP) and the Augmentation index (Aix) are normal for
age, but the Central Systolic pressure is outside of the normal range for this
patient’s age. The Software also displays the SphygmoCor reference age. The
SphygmoCor Reference Age for any given patient, is the age of healthy people in
the population who have similar PWA parameters SphygmoCor XCEL is a fast,
accurate and painless way to measure Central BP.

Central BP.
SphygmoCor XCEL PWA and PWV
The SphygmoCor XCEL PWA and PWV Device provides measurement of a
patient’s Central Aortic blood pressure and augmentation index in 60 seconds,
as well as a measurement of the patients carotid-femoral pulse wave velocity.
(cf-PWV).
To conduct a cf-PWV measurement, a cuff is placed around the
femoral artery of the patient to capture the femoral waveform, and a tonometer
pressure sensor is used to capture the Carotid waveform. The Pulses are
collected over a pre-set time, the Pulse transit time which is the time that the pulse takes to travel from
the carotid artery to the femoral artery. The distance between the Carotid and
femoral arteries is measured, and the velocity automatically determined by
dividing the distance by the Pulse transit time.
The Pulse Wave Velocity report, outlining the patient’s Pulse
wave velocity and a comparison to Healthy and General Populations is then
produced by the SphygmoCor software. In this example the patient has a Pulse
Wave Velocity of 6.3 m/s, which is a low level compared to both the Healthy and
General population.

carotid femoral pulse wave velocity
The SphygmoCor XCEL features:
- Measurement
of Central Blood Pressure or Pulse Wave Velocity in 60 seconds.
- Augmentation
index and Augmented pressure to assess peripheral arterial stiffness.
- Simple
PWA technique – place the cuff on the arm and press start.
- SphygmoCor
Brachial General Transfer Function – so you know it is accurate.
- Gold
standard carotid-femoral Pulse Wave Velocity – no undressing required.
- Data
equivalency with earlier SphygmoCor systems.
