The SphygmoCor® CPV System
The gold standard in noninvasive central blood pressure and pulse wave velocity assessment
SphygmoCor technology is the gold standard for noninvasive measurement of central blood pressure and pulse wave velocity. It has been featured in hundreds of published clinical studies, and is used in leading medical centers worldwide and in pharmaceutical clinical trials.PWA
PWA_PWV
SphygmoCor systems acquire the patient’s radical pulse wave form through a measurement taken at the wrist, derive the blood pressure wave form at the ascending aorta and report vital central blood pressure data.
The SphygmoCor CPV system also measures pulse wave velocity between two arterial locations.
Features
Instantaneous calculation of key parameters, including- Ascending Aortic Blood Pressure
- Pulse Wave Velocity--any two accessible arterial sites
- Aortic Pulse Presssure
- Aortic Augemtentation Index
- Ejection index
- Automatic, real-time QA feedback—minimal potential for operator variability
- Only one operator required
- Noninvasive tests, comfortable for patients
- Heart Rate Variability Option
Benefits
- Central pressure proven to be a superior, independent predictor of future cardiovascular events
- Allows assessment of vital drug effects that cannot be detected with brachial pressure measurement
- Provides patients with visual evidence of the effects of lifestyle changes and drug therapies
- Allows integrated analysis of aortic and arterial tree stiffness
