The RheoScreen® light is designed to guarantee an easy patient data handling and a comfortable data evaluation. This computer driven device is controlled through the RheoScreen software and can be joint with other devices of the RheoScreen family (e.g. the RheoScreen compact) to build a complete angiologic system. Moreover, the RheoScreen® light S is a self-contained system with its own display, a membrane switch and appropriate internal software. It can be used as a stand-alone device without a computer and the results are printed out on a small thermo printer. The rheoscreen light has an ECG-input and can be delivered also with a build-in pressure sensor. This makes it more suitable for pulse wave measurements.
