OxyFlo and OxyLab LDF
|
|
Latest Generation
|
|
|
Highly featured laser Doppler systems for continuous monitoring of microvascular blood perfusion from 1 to 4 tissue sites simultaneously. The latest generation systems incorporate new
developments in Digital Signal Processing (DSP) and laser Doppler flowmetry providing a technologically advanced, yet simple to use for multi-channel monitoring, setting new standards
for reliability and robustness.

|
Key Features
|
|
|
Simple to Use
No user-input or configuration - simply connect a probe and the system is ready for use.
|
|
|
'Smart' Probes
Once calibrated, 'smart' probe technology automatically recalls the calibration coefficients for a probe during subsequent use.
|
|
|
Ultra-fast Response Time
Real-time monitoring of physiological blood perfusion. Capable of resolving perfusion changes occurring over fractions of a second.
|
|
|
Multi-parameter Monitoring
Uniquely, the combination
of our blood flow monitors and our tissue oxygen monitors permits the measurement of pO2, blood perfusion and temperature from the same tissue site using a single combined probe (*OxyFlo
and OxyLab LDF models only).
