A vasopneumatic device is a tool designed to apply pressure in the body area it wraps. Vasopneumatic devices are usually built with two main components. First, an inflatable garment is wrapped around a section of the body and consists of multiple pressure compartments. The second part is an electrical pneumatic pump, which provides air or cold water. Vasopneumatic devices are machines built to pump the gas or liquid substance into the inflatable wrap, compressing the enveloped section of the body. It alternates inflation and deflation of the garment to provide treatment. Pressures applied will vary from one device to another.
