General description
The OxyFlo Pro is a microvascular blood flow monitor that is capable of
monitoring red blood cell (erythrocyte) perfusion in the microcirculation of a
tissue.
The monitor uses a technique referred to as Laser Doppler Flowmetry
(LDF), an established and reliable method for the measurement of blood
perfusion in microvascular research.
OxyFlo Pro probes plug into the OxyFlo Pro monitor, which contains the
laser source and sensitive photo-detection and signal processing circuitry.
Probes are standardised using a reference motility standard consisting of
latex microspheres undergoing Brownian motion.
Microvascular blood flow is indicated on the touch screen display in relative
units called Blood Perfusion Units (BPU).
The OxyFlo Pro laser Doppler blood flow monitor is available in two
configurations;
OxyFlo Pro
A dual-channel device, capable of monitoring up to two independent tissue
sites simultaneously.
OxyFlo Pro XL
A four-channel device, capable of monitoring up to four independent tissue
sites simultaneously.

List of Key Features
Continuous tissue blood flow assessment
Uncompromised reliability in continuous tissue blood flow assessment;
ideally suited to measurements of changing tissue blood flow in acute
experimental models.
Versatility
A range of probe types and probe formats provide support for a host of
specialist disciplines and applications requiring either invasive or non-
invasive tissue blood flow assessment.
ART
A proprietary artefact rejection technology that effectively filters out the
presence of motion artefacts in the blood flow signal. Substantially
reduces and in most cases, completely eliminates motion artefacts or
