PeriFlux 5000/6000 Laser Doppler

PeriFlux System 5000/6000

The system consists of main units and function units. Several main units, each equipped with four function units, can be connected in order to achieve the desired number of channels.

The modular design enables simultaneous monitoring of (laser Doppler) blood flow/perfusion and transcutaneous oxygen 1PERIMED – Transcutaneous Oximetry, by Dr. Caroline Fife. (2020, March 31).

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.

PF 5010/6010 – LDPM unit

PF 5010/6010 – 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.

With our PF 5010/6010 – 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.

PF 5020 – Temperature unit

PF 5020 – Temperature unit is used to perform local heat provocation and/or temperature measurements.
PF 5020 – Temperature unit has two connectors for either 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.

PF 5040/6040 – tcpO2/tcpCO2 unit

The PF 5040/6040 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 5050 – Pressure unit

PF 5050 – 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 5050 – Pressure unit can also be used to monitor cuff pressure with a precision sufficient for pulse volume recordings (PVR).
