Non-Invasive Optical Measurements of Edema Supporting CHF-Related Clinical Interventions
Congestive heart failure, or CHF, is a loss of cardiac function that results in the inhibition of oxygen transport throughout the body. Often associated with CHF is the presence of fluid accumulation in the lower extremities, which is referred to as edema. The standard method of quantifying edema is the ``Pitting Test`` which involves the application of pressure to the site of edema, which can be rated on a scale of severity. The goal of this work is to (1) develop algorithms that quantify the severity of edema and (2) apply optical probes used for deep tissue examination in order to determine appropriate anatomical locations for edema examination. This method of tissue examination is similar to that seen in a pulse oximeter, but the standards developed in this work will allow for greater applications of the same technology for home use in CHF patients. Because of the high rate of clinical readmission in CHF patients, the development of standards and technology that can be applied in a patient`s home can reduce their rate of readmissions while increasing their quality of life.
