This is an Ankle Brachial Index system (ABI) from Nicolet. It lets users perform basic vascular testing, which includes screening for peripheral artery disease. With spectral analysis technology, the VersaLab SE displays comprehensive information about all components of the blood flow. This helps to quickly delineate venous from arterial flow, and makes it easier to accurately indicate conditions such as turbulence. There are two models available for the portable Doppler system. The VersaLab is also available with 8 MHz or 4 MHz. The system features simple waveform traces that indicate the peak or mean blood flow profile. A tilt-stand allows the VersaLab unit to be mounted on the wall. It’s also battery or line operate for convenience and portability.
