Synopsis: This study examined the necessary pneumatic compression pressure and compression timing required to reach efficient fluid and lymph flow in limbs with lymphedema.
Abstract: Pneumatic compression of tissues with lymph stasis is, aside from the manual massage, a commonly used therapeutic modality in limb lymphedema. A number of pneumatic devices have been constructed. There is lack of reports of comparative studies determining inflation pressure levels, inflation/deflation cycle times, and total pumping times.
AIM: We tried to answer the question how high compression pressure and how long compression timing should be applied to the limb soft tissues to reach tissue fluid (TF) head pressure above 30 mmHg, necessary to initiate proximal flow.
METHODS: TF pressures were measured subcutaneously during intermittent pneumatic compression in the lymphedematous limbs stage II to IV. Pressures of 50, 80, and 120mmHg and timing 5, 20, and 50sec were applied.
RESULTS: a) the TF head pressures were lower than those in inflated chambers, b) inflation time of 5 and 20 sec was not long enough to generate TF head pressures above 30 mmHg, even if the compression pressures were as high as 120mmHg, c) the 50sec timing allowed to reach head pressures above 30mmHg; however, they remained always lower than in the compression chamber, d) TF head pressures differed at various levels of the limb depending on the soft tissue mass, e) deflation of the inflated whole sleeve for 5 and 20 sec was followed by high end pressures, whereas that of 50 sec brought about pressure drop to 0, facilitating refilling with TF of the distal parts of the massaged limb.
CONCLUSIONS: Our observations point to the necessity of applying high pressures and compression times over 50 sec, to generate effective TF pressures and provide enough time for creating TF flow. Short inflation times generate TF pressures as in one-chamber devices that preclude its effectiveness compared to the multi-chamber devices.

Hello. I’m interested in purchasing a device for home use. I kinda understand what the article is saying, but can you suggest a model of device that will supply the amount of pressure needed for over 50 second?
Many use a device called FlexiTouch by Tactile Medical and report good results.
I hope this helps.
