What is Air Pressure Therapy?
Barometric pressure therapy, also known as pneumatic compression therapy, is a treatment method that uses an inflatable garment or device to apply calibrated pressure to a specific part of the body. The garment is fitted around the targeted area, like the legs, arms, or abdomen, and inflated via an air pump or compressor. The pressure helps stimulate blood flow and drainage in that body part.
How Does Air Pressure Therapy Work?
When the pneumatic garment inflates, it applies graduated compression to the underlying tissues in a synchronized, sequential manner. Starting from the most distal part like the feet or hands, the garment inflates and gently squeezes the body upwards towards the heart. This squeezing action works much like a lymphatic drainage massage to push fluid and waste products along natural drainage pathways. The improved circulation and drainage help reduce swelling, relieve pain, and speed up healing.
Benefits for Lymphedema
Air Pressure Therapy is commonly used to treat lymphedema, a condition caused by impaired lymphatic drainage that results in swelling. With lymphedema, excess protein-rich fluid called lymph builds up in the swollen tissues. Pneumatic compression helps drain this excess fluid and reduces swelling. Regular use of pneumatic compression equipment helps manage lymphedema effectively and prevents further worsening of symptoms.
Wound Healing Benefits
Another key area where barometric pressure therapy provides benefits is wound healing. The increased circulation and drainage improve the delivery of oxygen and nutrients to injured tissues and removal of waste. Faster healing times have been reported with the use of intermittent pneumatic compression for wounds like pressure ulcers, venous leg ulcers, and traumatic injuries. The periodic pressure stimulates the growth of new blood vessels in the healing tissues.
Managing Deep Vein Thrombosis
For patients at risk of developing potentially life-threatening blood clots called deep vein thrombosis (DVT), intermittent pneumatic compression reduces that likelihood. Especially during periods of immobility like long flights or hospitalization, keeping the blood in the legs circulating via external compression prevents stasis and lowers clot formation risks. In some cases, it is used as an alternative to anticoagulant drugs that carry bleeding risks.
Relieving Pain from Phlebitis
Pneumatic compression garments provide effective relief from discomfort associated with phlebitis, the inflammation and clotting of leg veins. The pulsating pressure helps break down any clots while promoting venous return for quicker resolution of symptoms like swelling, discoloration and cramping pain. It prevents progression to more serious issues like post-phlebitic syndrome.
Post-Surgical Benefits
Following certain orthopedic procedures, barometric pressure therapy expedites post-surgical recovery. For joint replacements, it reduces the risks of post-op blood clots and associated complications. Swelling is managed faster, and patients are able to bear weight and regain mobility sooner with the help of pneumatic devices. It speeds up the rehabilitation process.
Potential for Other Uses
While primarily utilized for the indications mentioned above, researchers continue exploring additional applications. In sports medicine, it may help speed recovery from injuries by facilitating removal of lactic acid and other metabolic waste products accumulated during exercise. Some small studies found potential benefits for headache, back pain and vascular dementia as well. Larger trials are still needed, but pneumatic compression shows promise for an array of conditions.
Safety and Ease of Use
Being non-invasive, barometric pressure therapy is generally quite safe when used as directed. Easy-to-use home machines plug into a standard outlet for convenient therapy sessions. Computerized automatic units ensure pressure is delivered safely and effectively. Individuals receive proper training to use equipment independently. Minimal risks include skin irritation that is easily prevented with lubricants or padding inside sleeves. Overall, pneumatic compression offers a low-risk treatment option at any medical facility or home setting.
In summary, researchers and clinicians are advancing the use of pneumatic compression therapy beyond its conventional applications. As technology evolves to deliver more sophisticated pressure patterns, new potential benefits are uncovered regularly. Where mobility issues, surgery recovery or lymphatic concerns are present, pneumatic devices should be considered as part of an integrative care plan for optimal health outcomes.
