Skin Perfusion Pressure (SPP)

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 non-invasive test.

SPP measurements have proved useful in the assessment of peripheral arterial disease (PAD) for both critical limb ischaemia (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 ischaemia 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.

Equipment recommendations

The moorVMS-VASC system, including the laser Doppler monitor moorVMS-LDF, pressure cuff controller moorVMS-PRES and low profile fibre optic probe (VP11sc) have been specifically designed to aid micro vascular assessments in a variety of physiological research and clinical applications. The user friendly software can be used for single tests or any combination of tests according to your study requirements. This multi-functional system is easily configured enabling you to save user selected and defined test sequences or alternatively perform single tests of your choice. A range of tests are available and the software makes these simple to set-up, customise and perform.
