What is a Sequential Compression Device?
A S.C.D., often referred to as a lymphedema pump, is a form of vascular therapy that uses an electric or manual pumping unit that is connected to a garment such as a wrap, leg cuff, a boot or leg sleeve by and a tube or a series of tubes to deliver pneumatic (air) pulsation to produce a massaging effect that stimulates the muscle groups and vascular system in legs and feet.
This form of mechanical stimulation aids in minimizing the potential development of Deep Vein Thrombosis (DVT) and Peripheral Edema, particularly for those who are immobile for long periods of time.
Pneumatic sequential compression devices that are typically used in hospitals can contain up to ten inner chambers whereas most home units generally contain four to eight depending on the brand and model.
Sequential compression devices are often used when an arterial complication in the legs or feet has escalated to a more serious level prior and will not respond to high-compression TED hose.

How does a SCD work?
The lymphedema compression garment is placed around the area of the body that requires treatment and air is then fed by the compression pump through the tubes intermittently inflating and deflating the garment’s chambers in sequence (Battery powered portable units are also available and function using the same principle but delivers less pressure.)
A Pneumatic lymphedema press compression device is timed to compress the leg after each heartbeat, every other heartbeat or every third heartbeat, and is then at rest during moments of heart contraction and arterial inflow into the leg.
This allows the heart to empty its blood easier thus freeing it from having to work to return blood to the heart and decreasing the work of the heart contraction.
A similar device is a manual Lymphedema Foot Pump that directly stimulates the venous plantar plexus (large vein located in the foot) to increase blood circulation in non-ambulatory or bed-ridden patients by simulating the motion of blood produced during walking.

- Lymphedema Pump
- Foot Pump
- Intermittent Pneumatic Compression System
- Air compression leg wrap
- Hospital compression boot
Tips for selecting a Sequential Compression Device
- Rely on your doctor’s recommendations on what type of sequential compression device you should purchase which may include one of several popular brands (see below). Such devices can be somewhat complicated to operate if you’re new to using them and may require assistance.
It’s tempting to purchase an off-name brand to save a few dollars but if your doctor or health care physician who is familiar with your specific health situation makes a recommendation for a tested product for your situation, it’s advisable to follow his/her advice . - Don’t purchase a used or refurbished model – you don’t know what you’re getting! Going with a used model could put your health at risk if it doesn’t work properly. The investment you make in a compression pump machine will be one of the most important investments you make because it will help you live a longer and healthier life, allowing you to succeed at work and home and spend more time with family and friends. Unauthorized dealers may purchase your sequential compression device from a middleman. They may not work properly and you will never know. In addition, you may pay a significant amount of money and not have warranty coverage. The risk isn’t worth it.
- Avoid websites that offer cheaper brands of lymphedema products. Instead look for a website that offers machines with warranties from the quality manufacturers and offers free customer care and support. When you’re buying equipment that costs you or your insurance company hundreds to thousands of dollars you deserve access to customer support if you need it.
- Look for brands recommended by recognizable organizations, such as the American Diabetes Association (ADA). If you’re unsure about a specific brand contact the manufacturer directly or one of their distributors for information about their product offerings, warranties, and customer service so you can compare.
Sequential Compression Devices are sold to the consumer under a variety of terms, e.g., SCD*-boots, Portable Sequential Compression Device, Compression-Boot for Edema, Sequential Compression-Boot, Leg Compression Device, Lymphedema Pump, and Post-Surgical Anti-clot Leg Device.

Popular stand alone and portable Sequential Compression boots and leg messager devices
Auto-Edema-Reduction-boot – This device typically includes a cold pack option to provide cold therapy as well as compression to the leg to treat injuries related to sports or rigorous activities.
Some designs may include a grip sole to enable the user to walk while wearing the boot. This type of device can treat the entire lower leg and foot. Combined with the PresSsion sequential compression pump, it achieves the best of active and passive compression therapies.
The C-boot is not battery powered nor does it have external pumps, i.e. it is completely portable and depends on movement from your own body to generate power.
It has three chambers that inflate using a mini-compressor that starts at the ankle and works upward and includes a section for the foot, which does not inflate.
The C-Boot, often referred to as a pneumatic sequential-compression boot, is recommended for the treatment of vascular conditions such as leg ulcers, chronic venous insufficiency (CVI) and stasis dermatitis, lymphedema, and for the prevention of Deep Vein Thrombosis (DVT).
Verseo Cordless Air Pressure Leg Massager - The Verseo Cordless Battery Powered Leg Massager is a nice little compact leg wrap that is designed to improve circulation and counteract conditions that contribute to deep vein thrombosis (DVT) and embolism, serious blood clot condition and is approved by the FDA to improve blood circulation for those who must sit for extended periods of time.
Because there are no bulky tubes and external pump the Verseo Leg Massager can be worn anywhere; just wrap it around your arm or leg, turn it on and let the gentle automatic inflation and deflation cycles massage away tension, stress and pain.
It works by simulating the expansion and contraction of the calf muscles. The Verseo Cordless Leg Massager provides the same type of pressure as hospital compression boots, at a fraction of the time, cost, and inconvenience.
The massager delivers 70-130 mmHg of pressure, compared to the 15-20 mmHg delivered by compression stockings. It features 15-minute program and automatic modes, artificial-intelligence air pressure sensor, and three intensity settings. Fits calves and biceps up to 20″ in diameter. Requires two AA batteries (not included) that provide up to five hours of use. 4 1/2″ L x 2 1/2″ W x 2 1/2″ D.
Revitaleg Portable Pneumatic Compression Leg-Massager – RevitaLeg is an intermittent pneumatic compression massage device that helps improve circulation and reduces swelling caused by edema in the legs and feet for people who are inactive for long periods of time.
The RevitaLeg wraps around the leg and similar to an electric Sequential compression device pump it delivers a massaging action by the inflating and deflating of its cuff. The squeezing of the muscles acts as a pump to help improve circulation in the lower leg and foot.
Huntleigh Gradient Segmental Compression System Garment – This type of device is intended to treat lymphedema and venous insufficiency by delivering gradient segmental compression to the legs (also the arms).
It is available in a variety of sizes and is designed to prevent pinching and chafing.
The Huntleigh Gradient Segmental Compression System Garment comes with full-length zippers for easy application and removing (Console garments are sold as 1 garment per package, not sold in pairs.)
A bilateral connector is not needed to use two garments. The Huntleigh Gradient Segmental Compression System Garment is capable of providing arm and leg compression.
The measurement guidelines are simple one however the measurement will need to be done with some assistance.
The guidelines are as follows – Arm Length: Measure underarm to fingertips. Leg Length: Measure inseam thigh to heel.

Sallye-
Typically a SCD does not conduct heat to the area(s) it is being used on, or least none that I am aware of. That said, there are two possible reasons for the burn: some type of topical cream such as “icy hot” was applied to the skin prior to the garment being fitted. That in concert with the constant movement of the pressured pulsation or massage effect of the garment could possibly cause a skin reaction such as a “thermal burn”. Or, because there is little to no room for air circulation between the SCD garment and the skin, the massaging effect may have created enough friction, though ever so slight, to cause a burn or lesion, especially if the device was not working properly or was defective.
Whatever the reason, when the SCD was removed at the hospital the condition should have been immediately obvious to the care taker who removed it. I suggest that you contact his doctor or the hospital attendant(s) in charge of caring for your husband and relate the problem. This is particularly important as the area should be looked at and treated accordingly to help avoid the risk of inflection.

My husband was hospitaized after colon cancer surgery and wore the scd during his hospitalization.On his return home I discovered a very large thermal burn. Could the scd have caused this?

Linda-
Based on my understanding of any compression garments they should be removed prior to sleeping. That said I strongly suggest that you consult with your husband’s primary physician or health care provider about what kind of compression stockings or support socks he should be wearing, e.g., mmHg level, size, length, type and style, as well as the periods of times he could best benefit from wearing them.

Do you mean they should be only used for short periods of time. We were doing 10hrs lying in bed flat and sleeping. and why not?
So we should use this as a tool for when there is retention, when needed?
How long is a good time to use when in bed?

Q: After stopping the Kendall AV impulse 5000 my husband who is high level quad, has had no swelling in legs or water retention. Why is this?
A: The SCD performed its intended purpose, i.e., it successfully mechanically stimulated his blood and fluid flow to his heart and back by massaging the vascular cavities in his legs.
Q: We elevate at night and have no need. Is this normal?????
A: Slightly elevating his legs at night is a perfectly normal means of eliminating swelling. And no compression garment should ever be worn while lying prone for long periods of time whether sleeping or otherwise.

my question, after stopping the Kendall AV impulse 5000
my husband who is high level quad, has had no swelling in legs or water retention. Why is this? We couldn’t afford the socks any more. They were only lasting 1 month. We elevate at night and have no need. Is this normal?????
