Sequential Compression Devices


Sequential compression devices (SCD) are used in intensive care to reduce the risk of deep vein thrombosis (DVT) in the lower limbs of critically ill patients. SCD are sometimes referred to as ‘calf compressors’. DVTs are a serious complication associated with being immobile for a period of time.

How Do They Work?

SCD consist of plastic sleeves with a number of compartments and a pump. These plastic sleeves are applied to the legs, usually over thromboembolic stockings. The pump inflates and deflates the compartments with air in a predetermined sequence. This applies pressure to the muscles of the legs and a corresponding sequential compression to the veins of the legs. This serial compression of the muscles and veins mimics the action of walking and results in moving blood through the veins towards the heart and preventing pooling of blood in the lower limbs. Pooling or stasis of blood in the lower limbs increases the risk of DVT.

SCD are relatively comfortable to wear and do not restrict leg movement.

Are There Any Complications?

All Intensive Care interventions and procedures carry a degree of potential risk even when performed by skilled and experienced staff. Please discuss these issues with the medical and nursing staff who are caring for the patient.

Any Questions?

Of course, if you have any questions or concerns, please discuss them with the ICU nurses and doctors.
