What is PAD
Peripheral artery disease (also called peripheral arterial disease) is a common circulatory problem in which narrowed arteries reduce blood flow to your limbs. When you develop Peripheral Artery Disease (PAD), your extremities — usually your legs — don’t receive enough blood flow to keep up with demand.
PAD leads to ischemia (lack of oxygen), which leads to poor wound healing, pain during walking and/or during rest.
FlowOx cause rappid fluctuation in blood flow to your limbs, this can also be beneficial if you have other types of long standing chronic wounds.
FlowOx enhance circulation and in particular microcirculation which alleviate some of the problems associated with ischemia.
FlowOx enhances circulation and in particular microcirculation which alleviates some of the problems associated Otivio and various clinical groups have evaluated the impact of FlowOx technology on several hundred patients. Rapid fluctuations in blood flow by applying FlowOx technology in healthy, on patients with peripheral arterial disease or patients with spinal cord injury have been documented and published in numerous scientific studies. Clinicians in Norway, UK and Germany have evaluated FlowOx on patients with critical limb ischemia, diabetes and spinal cord injury, often with positive outcome. Patients with chronic pain are currently being evaluated in a clinical trial in Scotland. Additional data is being collected in clinical trials on patients with chronic wounds

Pulsating negative pressure applied locally, directly on the skin surface increases blood flow, probably due to a combination of dilation of the arterioles and an increased arteriovenous pressure gradient. The pulsating pressure will mechanically increase flow in the veins which have one-way valves. The reason for the pulsations is to avoid setting off the veno-arteriol reflex which constricts arteries when the veins are over-distended. That is also the reason why a constant negative pressure is counter productive
On the figure below (video shows the live Doppler signal), one can observe in the middle panel, how blood velocities (3) increase during the negative pressure period (1), whereas there is no change in the contra lateral control arm (5) not subjected to pressure pulses.
