Venous or blood pooling happens when the tiny valves in the veins get damaged and stop working correctly. īlood pooling, also known as venous pooling, is a condition in which blood collects in the lower extremities. In this regard, cuffs that only address the midpoint of the limb (for example calf only cuffs) or cuffs that have a gap between sections should be avoided due to the risk of blood pooling as the wrong cuff can damage the tiny valves in veins. Ĭuffs should always start at the distal (furthermost point) and move the blood to the proximal (center of the body). For examples of cuffs and uses, click here. Some manufacturers can support two people sharing a machine simultaneously this application is helpful for teams, clubs, and families. Circumferential cuffs provide a more consistent compression, and the calf deforms less than noncircumferential cuffs, which tend to compress the calf into a “flatter” shape. Measurements of interface pressure reveal that IPC cuffs that perform circumferential compression distribute force more evenly over the limb circumference than those that don’t. Cuff design is essential cuffs that overlap are better by design than those that don’t overlap as they promote a continuous movement of the blood without the risk of blood pooling that the seams in non-overlapping cuffs may cause. More cuffs are generally better, within reason, with six being a sweet spot in terms of benefits, functionality, convenience and intermittent pneumatic compression device cost. Other commonly used cuffs include Torso, full-length pants, and shorts (hip and glute focus).Ĭuffs have different chamber (air cell) number options, ranging from four to thirty six, depending on the application. The most commonly used cuffs for medical and athlete applications are leg cuffs and arm cuffs to move the blood volume from the distal to the proximal. Each mode and pressure range will have different applications. Treatment Timer Options tend to range from 5 to 99 minutes and pressure Range 30 – 240 mmHg. Manufacturers have different options, typically the controller will control between 1 and 4 recovery modes, and may include – Peristaltic, Sequential, Pulse & warmup modes. IPC Pumps (control units)Ī control unit is required to manage the inflation and deflation process required for IPC. Multichambered IPC devices have four to thirty-six chambers, with greater pressure in the distal chambers and lower pressure in the proximal chambers, resulting in a pressure gradient.Īdvanced compression systems may have just one to two and a half chambers active at any one moment, simulating the distal-to-proximal direction. Single-chamber IPC devices do not use a pressure gradient instead, they use a single cuff to deliver pressure to the upper extremities. It can be worn easily while sleeping or sitting in a chair. These devices are used in hospitals and homes equally as a part of recovery from surgery and in preventing clots formation in various conditions. The sleeves also assist the body in releasing chemicals that help avoid clots. When sleeves relax, oxygen-rich blood travels to the body through arteries. The compression aids blood flow from the body to the heart. This inflating and deflating action helps in circulation and the experience resembles massage. The sleeves inflate and deflate every 20 to 60 seconds. IPC devices keep the blood and lymphatic circulation smooth and help prevent these conditions. If any clots form in veins and arteries, it disturbs the circulation and leads to various diseases, i.e., deep vein thrombosis(DVT), stasis, and venous ulcers. Veins return oxygen-poor blood to the heart, and arteries take oxygen-rich blood from the heart and distribute it in the body. The stagnation of venous blood and lymphatic fluid is successfully driven back to regular circulation throughout the process of inflation, expansion, squeezing, and deflation. The intermittent pneumatic compression (IPC) devices provide compression per the predetermined treatment mode using an inflated sleeve that wraps around the body or limbs.
