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.
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.
