The modular design of PeriFlux 6000 Laser Doppler enables simultaneous monitoring of (laser Doppler) blood flow/perfusion and transcutaneous oxygen (TCOM, tcpO2) and/or carbon dioxide. Function units for heat provocation and pressure control are also available as well as a range of laser Doppler probes. The unit can use thermostatic laser Doppler probes and/or temperature measurement sensors.
Thermostatic laser Doppler probes allow for precise heating of the tissue at the measurement site. This can, for example, be useful to study the tissue reserve capacity.
Combined with Perimed’s dedicated software, the system offers complete and customized solutions for safe, smooth and simple workflows to investigate and assess the microcirculation.
PeriFlux 6000 Laser Doppler is widely used in applications, among others, such as;
The main unit is operated by a touch screen and can be equipped with up to eight function units. The function units are described below.
PF 6010 – LDPM unit
PF 6010 – LDPM unit (laser Doppler perfusion monitoring) is used for blood perfusion measurements based on laser Doppler technology. Laser Doppler measures the total, local microvascular flow including capillaries, arterioles, venules and shunts. One laser Doppler probe is used per unit. The unit can use thermostatic laser Doppler probes to allow for precise heating of the tissue at the measurement site.
With our PF 6010 – LDPM unit you can closely follow the dynamic changes in the microcirculation. Heart synchronous pulsations and even dicrotic notches can be observed. The system is also useful for studying responses to provocations such as heating, occlusion, drugs, posture, electrical stimulation, and more. This can, for example, be useful to study the tissue reserve capacity or maximum dilatation.
PF 6040 – tcpO2/tcpCO2 unit
The PF 6040 tcpO2/tcpCO2 unit measures the local tissue oxygenation or local carbon dioxide tension. The oxygen derives only from the local capillary (nutritive) blood perfusion. The carbon dioxide level is affected by both the local metabolic processes and the blood perfusion ability to remove carbon dioxide. One Clarke-type electrode is used per unit.
PF 6050 – Pressure unit
PF 6050 – Pressure unit is used to control linear or instant cuff pressure deflation. It has been developed to simplify and standardize tests such as peripheral pressure measurements (toe and ankle pressures), skin perfusion pressure (SPP) and post-occlusive reactive hyperemia (PORH). PF 6050 – Pressure unit can also be used to monitor cuff pressure with a precision sufficient for pulse volume recordings (PVR).
