Lymphatic Drainage Machines: What Pressotherapy Adds to a Body Room

What the machine actually does

Pressotherapy. Intermittent pneumatic compression. Sequential compression. The marketing names blur together, but the mechanism is the same: a pump inflates chambers inside a garment, one after another, squeezing the limb from distal to proximal. The pressure wave pushes fluid upward, assisting venous and lymphatic return. That's circulation support. That's comfort. It is not fat reduction.

One study measured tissue fluid pressures under a sleeve. Inflation to 50 mmHg generated pressures from 50 mmHg in the calf down to 10 mmHg in the groin. To 80 mmHg, the range was 80 to 20. To 120, it reached 40 in the upper thigh but still dropped off. Short inflation times produced mean tissue fluid pressure similar to a one-chamber sleeve. Twenty seconds of sequential inflation only managed 10-20 mmHg, regardless of whether the chamber pressure was 50, 80, or 120. Those numbers matter if you're trying to compare devices: a higher pump pressure does not automatically mean a higher pressure at the groin.

The border value for mobilising tissue fluid is 30 mmHg. Below that, you're mostly moving superficial fluid. Above it, you start to engage deeper lymphatics, but only if the inflation time is long enough to build threshold pressure. Five-second deflation periods are too short for tissue fluid pressure to drop back to zero. That means the next cycle starts from a compressed baseline. Quality of the cycle matters more than the maximum pressure printed on the pump.

The medical background and the boundary you must respect

Manual lymphatic drainage is a real technique with a clinical history. Combined physical therapy, which includes manual drainage, multilayer bandaging, exercise and skin care, is recognised as an effective treatment for lymphoedema. Intermittent pneumatic compression can be used as an adjunct to that therapy, particularly for patients with compromised mobility. Some studies show it reduces limb volume, but once the treatment stops, the volume increases again. There is no cure for lymphoedema.

So if a client walks in with a swollen arm after axillary lymph node dissection for breast cancer, that's not a spa add-on. That's a medical condition with its own protocols, contraindications and a need for proper diagnosis. You do not sell them a pressotherapy session. You refer them to a lymphoedema specialist. Full stop.

Even in a medical context, the use of intermittent pneumatic compression remains controversial. High pressures can damage lymphatic structures. Residual proteins left in the interstitial space can cause rebound oedema. The same systematic review that found IPC effective also noted there is no consensus on frequency or treatment parameters. That's not a blank cheque for a beauty therapist to improvise. It's a warning that the device is not a toy.

Why body rooms bundle it after cavitation

You already know the logic. A client books a cavitation session. You break down some fat cells. The triglycerides and cellular debris have to go somewhere. They enter the lymphatic system. So you put the client in a pressotherapy suit for 30 minutes to help move that fluid. It feels good. It looks like you're doing something extra. It gives you a reason to book the next session, because the client leaves feeling lighter and less bloated.

Does it improve fat loss outcomes? There is no study in our archive that proves that. What it improves is perceived value and retention. A salon running back-to-back sessions on a Saturday can keep a room turning over while the client does something passive. That's real revenue. Just don't pretend the machine is melting anything.

If you're building a body programme, the sequence matters. Our body programme guide walks through how to structure a course of cavitation, RF and cryolipolysis with appropriate intervals. Adding a pressotherapy session at the end of a cavitation treatment is a common pattern, but it's not mandatory. What is mandatory is that you explain to the client what the machine is doing: helping circulation and temporary fluid movement, not fat removal.

And if you're still shopping for the primary fat reduction device, look at our ultrasonic cavitation machines. We build those. We build cryolipolysis platforms and RF skin tightening too. We do not build a pressotherapy system. More on that in a moment.

Evaluating the hardware: chambers, garments, hygiene

A pressotherapy machine is a pump plus a set of garments. The pump is usually simple: a compressor, valves, a control unit. The garment is where the money goes. Chambers are the individual air cells inside the garment. More chambers mean finer pressure gradation, but only if the pump can inflate them independently and in sequence. A cheap system with eight chambers but a pump that inflates them all at once is just a squeeze.

Chamber count matters, but so does chamber shape. Overlapping chambers reduce gaps in pressure. Look for a garment that covers the limb without pinching at the joints. A sleeve that ends mid-thigh leaves the inguinal nodes uncompressed, which defeats the purpose. Full-leg garments with a separate abdominal section are standard for body work. Check the material: it needs to be cleanable. Sweat, oil and dead skin accumulate inside those sleeves. If you can't wipe it down between clients, you have a hygiene problem.

Pressure range is the next spec. Low-level evidence of moderate quality shows significant outcomes with 45-60 minute sessions at 30-60 mmHg in sequential programmes. That's a useful benchmark. A pump that maxes out at 50 mmHg is probably fine for wellness use. One that goes to 200 mmHg is a medical device hunting for a medical indication. Ask the supplier what the minimum and maximum pressures are, how many chambers can be controlled independently, and what the inflation and deflation times are. If they can't answer, walk away.

One more thing: the garment itself is a consumable. Zips break. Seams leak. The supplier should stock replacements and sell them at a reasonable margin. Ask about that before you buy the pump, not after.

Contraindications that matter in a body room

You need a screening checklist. Here's the minimum:

Acute deep vein thrombosis or phlebitis. Untreated or uncontrolled congestive heart failure. Severe peripheral arterial disease. Active skin infection, cellulitis or open wounds on the limb. Known or suspected pulmonary embolism. Acute inflammatory conditions of the limb. Malignant disease in the treatment area without medical clearance. Pregnancy. Severe pain or numbness of unknown cause.

That list is not exhaustive. If a client has any of those, no pressotherapy. If they have a history of lymphoedema, no pressotherapy without a medical referral. If they have varicose veins, use low pressure and avoid areas of visible bulging veins. If you're not sure, ask their doctor.

The same caution applies to compression garments worn after the session. A compression garment is not a substitute for medical compression stockings in lymphoedema management. It's a support garment. If a client needs medical compression, they need a prescription and a professional fitting. Selling them a one-size-fits-all sleeve from your retail shelf is not the same thing.

Post-treatment care matters too. Encourage hydration. Tell them to move around gently. No hot baths for a few hours. No alcohol. If they feel dizzy or nauseous during the session, stop and reassess. A pressotherapy session should be comfortable. If it hurts, something is wrong.

What to ask the supplier who does build one

We don't build pressotherapy machines. We build cavitation, cryolipolysis and RF platforms. So this is not a sales pitch. It's a checklist for when you talk to someone who does build them.

First, ask for the technical manual. Not the brochure. The manual should give you the pressure range, chamber count per garment, inflation time range, deflation time range, and whether chambers inflate sequentially or in groups. If it doesn't, that's a red flag.

Second, ask about safety certifications. The machine should have an electrical safety mark for your region: CE in Europe, FDA 510(k) clearance in the US, TGA in Australia, or the equivalent. Ask for the certificate number and verify it on the regulator's database. A supplier who won't give you the number is hiding something.

Third, ask about training. Who trains your staff? Is there a clinical protocol document? Does the supplier provide a contraindication list and a client screening form? If the answer is 'it's easy, you just put it on and press start', that's not training. That's an accident waiting to happen.

Fourth, ask about spare parts and warranty. How long is the pump warranty? How long is the garment life expectancy? Can you buy replacement garments as a separate SKU? What's the lead time? If the supplier can't answer these, you're buying a disposable.

Finally, ask about the evidence. The supplier should be able to point you to published studies on their specific device, not just on intermittent pneumatic compression in general. If they quote a figure like 'increases lymphatic flow by 400%', ask for the source. There is no consensus on optimal parameters, so any supplier who claims their device is the only one that works is lying.
