Overview

The OxyFlo™ Pro range takes the winning formula of our third-generation laser Doppler flowmetry technology and packages it into a compact, flexible form factor featuring a convenient touch-screen display and either 2-channel or 4-channels. The range topping 4-channel OxyFlo Pro XL can simultaneously drive up to 4 probes for the simultaneous monitoring of tissue perfusion from multiple tissue sites simultaneously.

OxyFlo™ Pro is intended for monitoring of relative microvascular blood flow in living tissues.
