One benefit of A-V

I'd never heard of the A-V impulse system until today. I learned about it from leaflets familiarising me with what to expect from my consultant surgeon tomorrow when he goes to work with his knife. The A-V impulse system involves a pair of ImPads that wrap around your feet after surgery. They are attached by two hoses to the A-V impulse system controller. The Impads mimic the natural action of the soles of the feet, improving blood circulation while the patient is lying prostrate. At last I have found some useful purpose to A-V.
