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
SphygmoCor® CVMS
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.

Porro prisms enable a lightweight, compact design. With 0.8x – 3.5x zoom magnification (SMZ445) and 0.7x – 3.0x zoom magnification (SMZ460), and diascopic/episcopic LED Stand, the SMZ445 and SMZ460 let you observe a wide range of specimens, from Petri dishes to plants, insects, small animals and minerals.
Nikon’s stereoscopic microscope with 7.5x zoom and 115 mm working distance — a superior model in this category.
Featuring a zoom magnification of 7.5X and a long working distance of 115mm, Nikon SMZ745 microscopes are well suited for both industrial and biomedical applications. The adoption of a new total reflection prism produces brighter images with higher contrast, and the anti-mold design allows the microscope to be used in environments where the temperature and humidity are high. The SMZ-745T trinocular model comes equipped with a microscope camera port and a built-in 0.55x c-mount adapter, permitting direct mounting of Nikon DS Series Digital Cameras.
Affordable Nikon Stereo Microscope model with 8:1 zoom ratio, streamlined operation and basic performance.
Versatile stereo microscope with improved operability and basic performance.
Nikon Stereo Microscope SMZ800N offers higher magnification than conventional models, enabling high-resolution observation of minute structures. In combination with the new objective series, its improved chromatic aberration correction provides bright and sharp images through the entire viewfield. The parallel optics design allows ergonomic accessories and observation attachments to be used in a wide range of applications.
Breakthrough new stereo microscope optics deliver the world’s highest zoom ratio of 25:1, higher resolution and brighter fluorescence images.
Traditional boundaries between scientific fields such as molecular biology and developmental biology are rapidly disappearing as researchers seek to connect findings at the molecular level to those derived from cellular, tissue, and organismal studies. Fields including molecular biology, cell biology, neurobiology, embryology, developmental biology and systems biology have increasing needs for imaging systems that span spatial scales from single cells to whole organisms.
With these demands in mind, Nikon has developed a stereo microscope that features a large zoom ratio of 25:1, high resolution and exceptional fluorescence transmission capability.
