Periferal Arterial Occlusive Disease, PAOD
Conditions
Brief summary
A study to assess the effect of negative pulsating pressure therapy on patients with impaired blood flow to the leg caused by arterial disease, to see if the FlowOx device will increase the blood flow to the leg in these patients.
Interventions
Boot-shaped pressure chamber generating pulsating negative pressure

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| % of the prescribed cycles delivered in the specified time FlowOx™-induced change in arterial leg blood flow (LBF) | up to 1 hour | This is calculated as the difference between the blood flow during the period using FlowOx™ (middle value over a period of 5 minutes) and baseline blood flow (middle value over a period of 5 prior to using FlowOx™) |
Secondary
| Measure | Time frame |
|---|---|
| Patient comfort measured by asking the patient a fixed set of questions | up to 1 hour |
Other
| Measure | Time frame |
|---|---|
| Fitting time | up to 1 hour |
