Effect on Blood Flow Using the FlowOx™ Device in Patients With Reduced Peripheral Circulation in the Lower Leg
This trial is active, not recruiting.
|Condition||periferal arterial occlusive disease, paod|
|Start date||August 2013|
|End date||December 2013|
|Trial size||20 participants|
|Trial identifier||NCT01893840, OT-FO-01|
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.
|Endpoint classification||safety/efficacy study|
|Intervention model||single group assignment|
5 minutes of pulsating negative pressure (10 sek og -40mmHg/7 sek of athmospheric pressure) will be Applied to the patient's leg
% of the prescribed cycles delivered in the specified time FlowOx™-induced change in arterial leg blood flow (LBF)
time frame: up to 1 hour
Patient comfort measured by asking the patient a fixed set of questions
time frame: up to 1 hour
Male or female participants from 30 years up to 90 years old.
