Components of Pneumatic Tourniquets
Modern pneumatic tourniquets have five basic components:
An Inflatable Cuff.
A Compressed Gas Source.
A Pressure Display.
A Pressure Regulator.
Connection Tubing.
Inflatable Cuff
Pressure is exerted on the circumference of an extremity by means of compressed gas, which is introduced into a bladder within the tourniquet cuff. All bladders have one or two port connectors for the attachment of connecting tubing. Typically, pneumatic cuffs are fastened by contact closures and may be secured with a ribbon tie to prevent cuff movement during the procedure.

Many different types of cuffs are available, and the appropriate choice is determined primarily by proper fit and surgical procedures. The choice of a tourniquet cuff should be individualized, taking into consideration the size and shape of the patient' s limb and the specific demands of the operative procedure. When selecting a cuff, consider the following criteria:
Cuff Location.
Single - vs. Dual - Bladder Design.
Cuff Shape.
Cuff Length.
Cuff Width.
Disposable vs. Reusable Cuffs.
Specialty Applications.
Limb Protection.
