Essential for hypertension management.

Products

Central arterial pressure waveform analysis and pulse wave velocity from the industry leader. 

SphygmoCor® technology is used clinically for central arterial pressure waveform analysis to better inform blood pressure management. The SphygmoCor system helps physicians individualize care for patients with hypertension, renal disease, COPD, diabetes and heart failure, among other diseases and conditions.

In clinical practice and clinical trials, SphygmoCor XCEL is the industry standard for noninvasive central arterial pressure waveform management. SphygmoCor XCEL provides measures of the central arterial pressure waveform and pulse wave velocity as well as an assessment of arterial stiffness via waveform analysis (e.g., augmentation index, augmented pressure and reflected wave magnitude).

PWA Test Image

SphygmoCor XCEL PWA (pulse wave analysis) uses a standard brachial cuff to measure brachial systolic and diastolic pressures, and capture a brachial waveform. The brachial waveform is then analyzed by SphygmoCor to provide a central aortic waveform. Central blood pressure measurements such as central aortic systolic blood pressure, central pulse pressure and an augmentation index are also reported.

 

PWV Test Image
To conduct a carotid-femoral PWV measurement, a cuff is placed around the femoral artery of the patient to capture the femoral waveform, and a tonometer is used to capture the carotid waveform. The distance between the carotid and femoral arteries is measured, and the velocity automatically determined by dividing the distance by the pulse transit time.

 

AtCor Medical has partnered with SunTech Medical, the ambulatory blood pressure monitor (ABPM) technology leader that introduced the first and only patented cuff designed specifically for ABPM use, to create an ABPM with SphygmoCor inside. This new gold standard, combined with measuring central arterial pressure waveforms and arterial stiffness, delivers a patient-focused solution with unsurpassed comfort, data reliability and confidence.

The SphygmoCor cardiovascular management system (CVMS) is a tonometry-based device used to noninvasively obtain vital cardiovascular data that cannot be obtained with traditional brachial cuff blood pressure measurements. SphygmoCor CVMS allows clinicians and researchers to measure the pressures that the heart, brain and kidneys actually experience.1

The SphygmoCor CVMS product line includes:

  • The SphygmoCor CP System
  • The SphygmoCor CPV System
  • The SphygmoCor CPVH System

The SphygmoCor CP System 

The SphygmoCor CP system includes pulse wave analysis (PWA) software only. During a PWA measurement, a 10-second snapshot of the radial arterial pressure wave is measured using a tonometer. The SphygmoCor software derives the ascending aortic pressure wave, substantially equivalent to the pressure wave measured by an invasive catheter. From the aortic pressure wave, a number of valuable cardiovascular measurements are determined, including central aortic systolic pressure, aortic augmentation index and central pulse pressure.

The SphygmoCor CPV System 

The SphygmoCor CPV system includes both pulse wave velocity (PWV) and PWA software. With the SphygmoCor CPV, PWV measurements can be taken between any two pulse points in the body; however, aortic PWV, measured with readings at the carotid and femoral arteries, has been shown to be the most predictive of cardiovascular risk.

The SphygmoCor CPVH System 

In addition to pulse wave velocity and pulse wave analysis software, the SphygmoCor CPVH system also provides heart rate variability (HRV) software. The SphygmoCor HRV software provides analysis of both time and frequency domains, and measures of sympathetic and parasympathetic activity. The system allows standard HRV measurements to be measured over 6 hours, as well as Valsalva and standing maneuver HRV measurements to be performed.
