Postoperative deep vein thrombosis (DVT) is a major health threat for long-term bedridden patients. According to statistics, the incidence of DVT after untreated abdominal surgery is as high as 40%, and the pulmonary embolism caused by DVT is one of the main causes of postoperative death. Traditional prevention methods rely on anticoagulant drugs, but the risk of bleeding is always hanging over doctors and patients like the sword of Damocles. Nowadays, an innovative physical prevention method - pneumatic therapy is becoming a new favorite in the medical community, and its safety and effectiveness have aroused wide concern.

Air compression therapy System: the pioneer of non-invasive guardian
The air compression treatment system simulates the squeezing effect of muscle contraction on the veins through the leg compression massage boots that are periodically filled with air to promote the blood return of the lower limb veins. This kind of physical therapy completely avoids the burden of liver and kidney caused by drug metabolism and bleeding complications. Recent clinical studies have shown that patients using air compression leg massagers have a 28% lower incidence of postoperative DVT than those in the drug group, and there are no serious device-related adverse reactions.

Data comparison highlights security advantages
A controlled study in the vascular surgery department of a top-three hospital was convincing: 1,200 orthopedic postoperative patients were divided into a drug group (low-molecular-weight heparin injection) and a barometric group (twice-daily air-wave pressure treatment). The results showed that the incidence of DVT in the two groups was 8.3% and 5.7%, respectively, while the incidence of bleeding events in the barometric group was only 1/5 of that in the drug group. Experts pointed out that this non-drug intervention is particularly suitable for people with high blood risk, such as those with coagulation disorders or limited early postoperative activities.

Smart technology enables precise prevention
A new generation of DVT prevention devices has been equipped with smart sensing technology. Taking a brand of air compression treatment system as an example, its built-in pressure sensor can monitor the change of limb circumference in real time and automatically adjust the pressure gradient to ensure the accuracy of treatment. The leg compression massage boots equipped with the equipment adopt the medical-grade gradient pressure algorithm, which decreases from ankle to thigh in turn, and perfectly replicates the muscle pumping effect under physiological conditions. According to patient feedback, this "thinking leg massager" improves treatment comfort by 40%.

Medical consensus: Physical prevention should be standard
The latest guidelines from the International Society for Vascular Surgery clearly state that barometric therapy should be used as a first-line preventive measure for patients with low - and medium-risk surgery. A number of domestic top three hospitals have incorporated it into the routine process of postoperative care. The director of the nursing department of a provincial hospital said: "The air compression therapy system not only reduces the risk of DVT, but also promotes the implementation of the concept of rapid rehabilitation after surgery. Patients get out of bed 1.5 days earlier on average, and hospitalization costs are reduced by about 12%."

With the accumulation of evidence-based medical evidence, barometric therapy is evolving from an auxiliary means to a mainstream preventive program. For medical institutions that pursue safe and efficient postoperative care, the air compression treatment system undoubtedly provides a more solid umbrella for both doctors and patients. When technological innovation and clinical needs perfectly collide, postoperative DVT prevention is opening a new chapter.
