Lymphoedema Compression Levels: Understanding mmHg in Compression Therapy

lymphoedema compression

Compression therapy is essential for lymphoedema management, and therefore, is worth it write a blog where we are going to talk about what compression is ideal for what lymphoedema presentations, including the mmHg levels. I’m Giovanni, and I run Melbourne Massage and Treatment, a Myotherapy and Lymphoedema clinic in Fitzroy North. I trained with the Vodder Academy in lymphoedema management, and I provide Complete Decongestive Therapy (CDT), which forms the foundation of effective lymphoedema treatment.

What Does mmHg Mean in Lymphoedema Compression?

As when measuring blood pressure, even when working with Lymphoedema, we use the measuring unit mmHg (millimetres of mercury) when talking about compression. Based on the type of presentation, as lymphoedema therapists, we would recommend different types of compression garments, including flat knit or circular knit.

So, here is a short list of the purposes of compression garments:

  • Support the lymphatic system
  • Encourage lymphatic flow
  • Prevent fluid from re-accumulating
  • Maintain the results achieved through CDT

Therefore, choosing the correct mmHg compression level is about balancing effectiveness, safety, and comfort, and not only apply some form of pressure on the affected limb.

Compression Classes and Lymphoedema Management

To simplify how compression garments work, companies like Sigvaris or Juzo grouped the compression into classes or levels, each corresponding to a specific mmHg range.

Common Compression Levels Used in Lymphoedema Compression

Lower compression levels – 15–20 mmHg
Often considered in:

lymphoedema compression

  • Mild lymphoedema
  • Early-stage swelling
  • Fragile or sensitive skin
  • Situations where tolerance is limited

Moderate compression levels – 20–30 mmHg
Commonly used for:

Higher compression levels – 30–40 mmHg
Usually required for:

  • Moderate to severe lymphoedema
  • Fibrotic or hardened tissue
  • Significant limb shape changes
  • Swelling that rebounds quickly

My personal suggestion is that the correct Compression Level should always be determined following a thorough clinical assessment, in order to avoid fluid retention and waste of money.

Why Higher Compression Is Not Always Better

Compression level in lymphoedema treatment, as mentioned above, has to be a balance of effectiveness and comfort, and different presentation, with or without fibrosis, mobile or immobile limb, comes with different compression needs. Indeed, applying the wrong type of compression can:

  • Reduce comfort and compliance
  • Increase skin irritation or skin breakdown
  • Compromised lymph circulation
  • Make garments difficult to don and doff

In fact, effective Lymphoedema Compression works with the body, not against it, and that’s why for lymphedema presentation compression garments are recommended to be worn after taking specific measurements, that ensure a gradient pressure is applied on the limb, so that the lymph fluid is pushed in the right direction and not towards the extremity of the limb.

Compression Levels and Complete Decongestive Therapy (CDT)

At Melbourne Massage and Treatment, as part of lymphedema management, I offer MLD as a manual therapy to stimulate the lymphatic system, and CDT (Complete Decongestive Therapy), to reduce the swelling and limb size.

More specifically, CDT, can help with:

  • Reduce swelling after the delivery of Manual Lymphatic Drainage (MLD)
  • Improve tissue quality
  • Shape the limb appropriately
  • Prepare the limb for long-term Lymphoedema Compression
  • Help in the breakdown of fibrosis

Once the limb has stabilised, compression garments help maintain volume reduction and prevent progression of lymphedema.

Professional Assessment Is Essential

Certain pharmacies or retail shops (including online one) may sell compression garments, but those are probably not specific enough for a Lymphoedema presentation. Indeed, the appropriate Compression Level depends on:

  • Lymphoedema stage
  • Limb shape and size
  • Tissue texture and fibrosis
  • Skin condition
  • Functional needs and daily activity

For compression garments, post MLD and CDT therapies, I refer patients to Sigvaris in West Melbourne, which specialises in medical compression for lymphoedema and ensures accurate fitting and garment selection.

Accessing Compression Garments Through the SWEP Program

For some people living with lymphoedema, the cost of Lymphoedema Compression garments can be a barrier to effective long-term management. In Victoria, eligible patients may access support through the State-Wide Equipment Program (SWEP), which provides funding for medically necessary aids, including compression garments for lymphoedema. As a Clinical Myotherapist, I can help you go through the SWEP program in collaboration with your GP. The role of the GP is to write a diagnosis and a referral to the SWEP program, and that’s where I can assist them. After that, you can refer to an approved compression provider, such as Sigvaris in West Melbourne, who can advise on garment selection and fitting.

The Swep program for Lymphoedema patients can help with:

  • Reduces the cost of Lymphoedema Compression garments for eligible patients
  • Supports long-term lymphoedema management after Complete Decongestive Therapy (CDT)
  • Ensures clinically appropriate compression through professional assessment

FAQ – Lymphoedema Compression Levels

In short, compression therapy is a key component of lymphoedema management. But to tell you more, it involves wearing medical-grade compression garments that apply graduated pressure to the lymphoedema limb. The application of compression, on long term, it is essential for supporting the lymphatic system, encourages lymph flow, prevents fluid from re-accumulating, and helps maintain the results achieved through Manual Lymphatic Drainage and Complete Decongestive Therapy (CDT).

mmHg stands for millimetres of mercury and refers to the amount of pressure applied by a compression garment. This unit defines what type of compression is best for your type of lymphoedema by considering an effective, safe, and comfortable approach based on your lymphoedema presentation.

Ensuring that you are wearing the right type of compression would guarantee that your presentation would not get worse. Not enough compression may not control swelling, while too much compression may lead to discomfort, skin irritation, or reduced compliance.

For a mild or early lymphedema, lower compression levels are used. For lower levels of compression, we refer to 15 and 20 mmHg. But this type of compression is also used for fragile skin or when tolerance to compression is limited.

When looking at more established lymphedema, or a more severe presentation, moderate compression levels are recommended. In these cases, we look at 20 and 30 mmHg, which are indeed recommended, especially after intensive CDT, to maintain limb volume.

Higher compression levels, such as 30 to 40 mmHg, are usually required for moderate to severe lymphoedema, fibrotic tissue, or swelling that rebounds quickly without compression.

Higher compression is not always better. Incorrect compression can reduce comfort, increase skin irritation, compromise lymph circulation, and make garments difficult to use consistently.

To ensure the best results, the compression garments are best when made to measurements. This allows a tailored fitting on your limb lymphoedema presentation. Indeed, graduated compression, with higher pressure distally and lower pressure proximally, is known to help the lymph fluid move in the correct direction.

The compression applied during CDT is bandaging, which wraps around the affected limb. Those bandages maintain a certain level of pressure (we aim for 40mmHG, at the thickest spot) to support the lymph flow, which was initially stimulated by MLD. This has a double effect: one is to reduce the lymphoedema swelling, and the second is to break potential fibrosis.

I would not recommend that. Over-the-counter compression garments are often not suitable for lymphoedema. The correct garment depends on lymphoedema stage, limb shape, tissue texture, skin condition, and daily activity. The risk is to buy something that would not help your presentation, which would lead in a waste of money.

Yes, I do. At Melbourne Massage and Treatment in Fitzroy North, I provide personalised lymphoedema management, and I collaborate with specialised compression providers for accurate garment fitting.


Yes, you can. Once lymphedema is diagnosed, you may be eligible for compression garment support through the SWEP program. A clinical assessment is essential, and approved providers manage the application and fitting process to ensure the correct Lymphoedema Compression is prescribed.
