The mode of action
In intermittent pneumatic compression (IPC), garments on the leg are filled with air pressure in fixed cycles and then released. This sequential compression supports venous return from the legs to the heart and counteracts a stasis of the blood in the deep veins — one of the central risk factors for venous thromboembolism.
Unlike pharmacological prophylaxis, IPC does not interfere with blood coagulation. This makes it an important option when medication is not an option — and a sensible addition in high-risk settings.
Areas of use
- Postoperative (surgery, orthopaedics, vascular surgery, gynaecology)
- Intensive care for immobilised patients
- When pharmacological prophylaxis is contraindicated
- Adjunctive in high-risk settings following a risk assessment
Framing & evidence
Mechanical thromboprophylaxis by means of IPC is anchored in the S3 guideline on VTE prophylaxis (AWMF 003-001); a separate S1 guideline (AWMF 037-007) addresses the method in detail. More on this on our page on the S3 guideline and in the overview of the body of studies.
Frequently asked questions
What is intermittent pneumatic compression (IPC)?
IPC is a mechanical method of thromboprophylaxis. Inflatable garments on the calf and/or thigh are cyclically pressurised and released. This promotes venous return and supports blood flow in the deep leg veins.
How does IPC differ from pharmacological prophylaxis?
IPC works purely mechanically, without affecting blood coagulation. It is therefore an option in particular when pharmacological prophylaxis is contraindicated — or as an addition in high-risk settings.
When is IPC contraindicated?
Among others, in acute deep vein thrombosis and in advanced peripheral arterial occlusive disease. The assessment of indication and contraindication is made by the treating professionals.
Which device does UniCare use?
The Phlebo Press® DVT 650 Easy from Mego Afek — a mobile IPC compression device with automatic pressure control, quiet operation and CE conformity under the MDR.
