The VQ•Flow is an easy to use, portable, sequential pneumatic compression system to help reduce the risk of Deep Vein Thrombosis (DVT) in patients by stimulating blood flow in the extremities. Intermittent pneumatic compression is commonly used after surgery to reduce the incidence of adverse pulmonary events, prevent re-admission and reduce overall costs. The VQ•Flow can be used post-surgically for DVT prevention as well as adjunctively for the treatment of venous stasis ulcers, arterial and diabetic leg ulcers, chronic venous insufficiency and reduction of edema.
