Laser-Doppler Probes for the Evaluation of Arterial Ischemia

  • Chapter
Continuous Transcutaneous Monitoring

Part of the book series: Advances in Experimental Medicine and Biology ((ABBI,volume 7))

Summary

Rhythmic variations of microvascular flux have been studied at the forefoot of patients with arterial occlusive disease by laser-Doppler flowmetry. Two patterns of flow motion with characteristic amplitudes and frequencies could be observed. The prevalence of small waves with a mean amplitude of 0.21 ± 0.1 AU and a frequency of 21.7 + 4.2 c/min increased with the degree of ischemia. Big flow motion waves with a mean amplitude of 0.77 ± 0.4 AU and a frequency of 3.0+1.0 c/min were found in both controls and patients with different degrees of ischemia. The small waves may represent a compensatory mechanism in skin ischemia.
