Effects of forced deep breathing on blood flow velocity in the femoral vein: Developing a new physical prophylaxis for deep vein thrombosis in patients with plaster cast immobilization of the lower limb

Forced deep breathing significantly increased PBVFV in patients with plaster cast immobilization of the lower limb in both supine and sitting positions. Testing the efficacy and adherence in clinical contexts, and following up with the incidence rate of DVT in future studies, is necessary for the development of a new physical prophylaxis for DVT.
