Electromed, Inc. develops, manufactures, markets and sells innovative products that provide airway clearance therapy, including the SmartVest Airway Clearance System and related products, to patients with compromised pulmonary function with a commitment to excellence and compassionate service. The SmartVest System features a programmable air pulse generator, a therapy garment worn over the upper body and a connecting hose, which together provide safe, comfortable, and effective airway clearance therapy. The SmartVest System generates HFCWO, also known as High-Frequency Chest Compression, a technique for airway clearance therapy. The garment repeatedly compresses and releases the upper body at frequencies from 5 to 20 cycles per second creating a “mini cough”. Each compression (or oscillation) produces pulsations that thin and loosen secretions from the surfaces of the lung airways, thins mucus stuck in the lungs and propels them toward the mouth where they can be removed by normal coughing or suction.
