A pneumatic compression pump is a basic component of intermittent pneumatic compression (IPC), a widely used technique that involves attaching an electrical air compression pump to an inflatable plastic garment that is placed over the affected limb.
The principles of pneumatics are the same as those for hydraulics, but pneumatics transmits power using a gas instead of a liquid. Compressed air is usually used, but nitrogen or other inert gases can be used for special applications.With pneumatics, air is usually pumped into a receiver using a compressor.he principles of pneumatics are the same as those for hydraulics, but pneumatics transmits power using a gas instead of a liquid.
