Sequential Intermittent Pneumatic Compression (SIPC)
If you’re living with lymphoedema, lipoedema, or chronic wounds, you may have heard about Sequential Intermittent Pneumatic Compression (SIPC). This evidence-based therapy is increasingly used alongside compression garments, exercise, and other conservative treatments to help manage swelling, support lymphatic function, and improve quality of life.
But what exactly is SIPC and who may benefit from it?
What is Sequential Intermittent Pneumatic Compression (SIPC)?
Sequential Intermittent Pneumatic Compression (SIPC) is a form of external compression therapy that uses a garment containing multiple inflatable chambers connected to a pneumatic (air) pump. The chambers inflate and deflate in a programmed sequence, creating a controlled distal-to-proximal pressure gradient that promotes fluid movement through the lymphatic and venous systems.
Unlike static compression garments that provide constant pressure, SIPC delivers dynamic, cyclical compression designed to mimic and support the body’s natural fluid transport mechanisms. By enhancing fluid clearance, SIPC can help reduce swelling, tissue congestion, heaviness, discomfort and associated functional limitations.
What to Expect During a SIPC Session
For many people, SIPC is a new experience, and knowing what to expect can be helpful.
During a session:
- You will be fitted with a garment over the affected limb or body region
- The device will inflate in cycles, creating a wave-like squeezing sensation
- The pressure is typically firm but should remain comfortable
- Sessions commonly last between 30–60 minutes, depending on prescription and available treatment time
- Many people feel a sense of lightness or reduced heaviness afterwards
- Some individuals notice increased urination as fluid shifts and is processed by the body
SIPC is generally well tolerated and settings are adjusted to suit individual comfort and clinical needs.
What Conditions Can SIPC Be Used For?
SIPC may be considered as part of a comprehensive management plan for conditions involving fluid accumulation, including:
- Primary and secondary lymphoedema
- Lipoedema
- Lipo-lymphoedema
- Chronic oedema
- Venous insufficiency
- Venous leg ulcers
- Post-surgical swelling
SIPC is an adjunctive therapy and is not intended as a standalone treatment for these conditions.
Are All Compression Pumps the Same?
No, not all pneumatic compression devices are created equal.
Medical-grade systems used in clinical management are specifically designed to support lymphatic and venous function safely and effectively. Devices such as those available through Medi-Rent and LymphaPress utilise advanced technology that allows clinicians to tailor treatment parameters to an individual’s condition and goals.
In contrast, lower-cost or non-medical devices (such as those purchased online) may have fewer chambers, limited pressure control, or simplified inflation patterns. While they may provide a sensation of compression, they may not deliver the same therapeutic precision required for complex medical conditions.
Key Features of Medical-Grade SIPC Devices
Medical-grade systems typically include:
- Multiple overlapping chambers for precise fluid movement without limb banding
- Adjustable pressure settings tailored to the individual
- Programmed treatment modes for different clinical presentations
- Garments that can treat the upper limbs, lower limbs, trunk, or chest
- Pre and post-treatment lymph node clearance
These features allow treatment to be individualised rather than applying a ‘one-size-fits-all’ approach.
SIPC for Lymphoedema
Lymphoedema occurs when the lymphatic system is unable to effectively transport lymphatic fluid, leading to persistent swelling, heaviness, discomfort, and tissue changes over time.
SIPC is commonly prescribed as part of a comprehensive lymphoedema management plan. The sequential compression pattern helps encourage fluid movement from the affected area towards functioning lymphatic pathways, supporting lymphatic drainage and reducing fluid accumulation.
Evidence suggests SIPC can assist with:
- Limb volume reduction
- Symptom relief
- Functional improvement
- Long-term maintenance when used alongside compression garments, exercise, skin care, and education
Importantly, SIPC should complement, not replace, Complete Decongestive Therapy (CDT), which includes compression therapy, exercise, manual lymphatic drainage, skin care, and self-management strategies.
SIPC for Lipoedema
Lipoedema is a chronic condition characterised by abnormal, symmetrical fat distribution most commonly affecting the legs. Symptoms often include pain, tenderness, heaviness, bruising, and fluid retention within the tissues.
While SIPC does not reduce lipoedema fat tissue, it can help address the fluid and inflammatory component that often contributes to symptoms. By supporting venous and lymphatic return, SIPC can reduce sensations of heaviness, tightness, and swelling.
In cases where lymphatic compromise is present (lipo-lymphoedema), SIPC can play an important role in managing fluid accumulation and supporting symptom control.
SIPC for Chronic Wound Healing
Chronic wounds, particularly venous leg ulcers and wounds associated with chronic oedema, often occur in the presence of impaired circulation, persistent swelling, and reduced tissue health. Excess fluid in the tissues can reduce oxygen and nutrient delivery, slowing healing processes.
SIPC can support wound healing by:
- Reducing swelling
- Improving venous return
- Enhancing local circulation
- Supporting tissue oxygenation
- Creating a more favourable environment for tissue healing
SIPC is used alongside standard wound care practices, not as a replacement.
What Does the Research Say About SIPC?
A growing body of evidence supports the use of SIPC as an adjunct therapy for lymphoedema, chronic oedema, venous disease, and chronic wound management.
Depending on the individual, SIPC has shown to help support:
Reduced swelling by assisting fluid movement and contributing to long-term oedema control
Symptom relief, including reduced feelings of heaviness, tightness, aching, and discomfort
Improved mobility through reduced limb weight and enhanced physical function
Enhanced self-management as a convenient home-based adjunct therapy
Improved tissue health by reducing prolonged fluid accumulation and the risk of tissue fibrosis
While some individuals experience symptom relief soon after commencing treatment, measurable reductions in swelling may take days or weeks, depending on the severity of the condition and consistency of use.
Importantly, the strongest outcomes are consistently reported when SIPC is used as part of a comprehensive management program that includes compression therapy, manual lymphatic drainage, exercise, skin care, and patient education.
Can Everyone Use SIPC?
No, SIPC is not suitable for everyone and use should always be guided by clinical assessment.
Contraindications or precautions include:
- Acute cellulitis or infection
- Acute deep vein thrombosis (DVT)
- Uncontrolled heart failure
- Certain vascular conditions
- Other unstable medical conditions affecting fluid balance
Assessment by a trained healthcare professional is essential to ensure safe and appropriate use. SIPC is only prescribed by accredited lymphoedema therapists, with ongoing monitoring and adjustment required based on response.
Clinic Use vs. Home Use
SIPC may be used in different settings depending on individual needs:
Clinic-based SIPC
- Used for treatment trial
- Allows supervised adjustment of settings
- Often used in the intensive treatment phase
- Used in more complex cases
Home-based SIPC
- Prescribed for ongoing maintenance
- Supports long-term self-management
- Requires regular review and monitoring to ensure safety and effectiveness
Both approaches are often used together over the course of treatment.
