The Pedra perfusion system measures microvascular flow through diffuse speckle contrast analysis. It will be used to assess changes in perfusion in response to a number of physiological stimuli. It will be compared to other standard diagnostics including ankle-brachial index, toe-brachial index and transcutaneous oxygen measurement. Measurements will be undertaken in non-vascular patients as well as those with chronic limb threatening ischaemia.
