Tonometry of Deep Tissues for Setting Effective Compression Pressures in Lymphedema of Limbs.

Background: The therapeutic intermittent pneumatic compression (IPC) pressures are usually set arbitrarily at levels between 40 and 60 mmHg. However, it is not known how much force has been transferred to edema fluid. There is a need to know how high edema fluid pressures should be generated to evacuate the stagnant fluid.
