Heat controlled laser Doppler

Heat combined with laser Doppler can be used to determine the viability of tissue and the degree of microcirculatory impairment. The increase in blood perfusion as a response to local heating indicates tissue reserve capacity and endothelial function. These are important parameters for predicting healing and determining amputation level.

PeriFlux 5000 LDPM

The PeriFlux 5000 laser Doppler perfusion monitor is a modular system with up to four function units e.g.  laser Doppler unit, temperature unit or pressure unit. In combination with the thermostatic probe 457, it can be used to study the response to local heating.

Endothelial Dysfunction

Heat controlled laser Doppler is an increasingly used method to study the endothelium and assess the subject's endothelium dependent and endothelium independent vasodilation when subjected to local heating.

Improving quality of life since 1981

Perimed AB, established in 1981, provides instruments, software and expertise to enable assessment of the microcirculation. We utilize laser Doppler, laser speckle (LASCA) and transcutaneous oxygen (tcpO2 or TCOM), to accurately monitor and quantify blood perfusion and tissue oxygenation in real-time. Our modular PeriFlux System 5000 and PeriFlux 6000, the latest generation of our PeriFlux System, are excellent choices for diagnosing Peripheral Arterial Disease (PAD) and Critical Limb Ischemia (CLI) or for assessing wound healing potential in your vascular patients. Our blood perfusion imager PeriCam PSI System allows you to investigate spatial distribution, for example during cortical spreading depression.
