objectives the main objective of this study was to design and construct an optical device to determine the rbv in patients undergoing hemodialysis, during the process. materials and methods after initial studies in order to select a proper sensor, using the orcad software, an analog circuit was designed. the implementation and modification of the circuit was done by the clinical tests, using ex...

Measurements of pulmonary blood volume (PBV) and pulmonary capillary blood volume (V,) and hemodynamic studies were made in a series of 106 patients with valvular heart disease (62 with predominant mitral lesions and 44 with predominant aortic lesions). The results were compared with the data obtained from 14 "normal" patients and nine normal subjects. In 14 "normal" patients, the PBV varied fr...
