Modern pneumatic tourniquets have three basic components:

an inflatable cuff, a compressed gas source, and an instrument which automatically monitors and controls cuff pressure.

The cuff is secured around the limb proximal to the operative site. Pressure is exerted on the circumference of the limb by means of compressed gas which is introduced into the tourniquet cuff by a microprocessor-controlled source, via connection tubing. When sufficient pressure is exerted, vessels and arteries beneath the cuff become temporarily occluded, preventing blood flow past the cuff. While the cuff is inflated, the tourniquet system automatically monitors and maintains the pressure chosen by the user. Cuff pressure and inflation time are displayed, and an audiovisual alarm alerts the user to alarm conditions, such as a cuff leak.

Studies have shown that tourniquet cuff pressures can be substantially reduced without compromising the quality of surgical field by using wide, contoured cuffs. Wide cuffs also reduce the risk of injury to underlying tissue by dispersing the cuff’s force over a greater surface area. Standard cuffs are relatively narrow in width and are cylindrical in shape. Where there is a significant difference in limb circumference between the distal and proximal edges of the cuff, a contoured cuff with a tapered, conical shape provides a more anatomical fit and maximizes the contact area between cuff and limb. Wide cuffs with an adjustable, variable taper have recently been introduced, permitting one cuff to conform to a variety of limb shapes
