• Evaluates micro-circulation.
• Predicts wound healing outcome.
• Detects PAOD and CLI in the early stage

Skin Perfusion Pressure (SPP) is the pressure required for restoring microcirculatory blood flow following release of carefully controlled occlusion. The measurement of SPP with laser Doppler is a noninvasive test.
SPP measurements have proved useful in the assessment of peripheral arterial disease (PAD) for both critical limb ischemia (CLI), and also for the determination of optimal levels for amputation. There are also indications in the literature that SPP measurements are useful indicators for wound healing potential, and more recently for the investigation of ischemia over the ischial tuberosity in people with spinal cord injury. SPP provides a good indication of the status of the proximal arterial system whilst remaining unaffected by conditions such as arterial wall calcification (commonly seen in diabetic patients with PAD for example).
Foot SPP has also been shown to correlate well to toe pressure and would be useful in situations where toe blood pressure measurements are not possible, due to toe amputation, ulceration or gangrene.

• Non-invasive.
• Easy and quick operation.
• Not affected by vascular calcification.
