Optimal hematocrit for oxygenation of canine intestine.
To determine the direct effects of hematocrit on intestinal oxygen consumption and to determine whether an optimal hematocrit exists for intestinal oxygenation, we perfused isolated canine gut loops at a constant pressure (120 mm Hg) and varied hematocrit from 80% to 10%. As hematocrit fell, blood flow rose while arterial oxygen content fell. The regression of blood flow on hematocrit was linea...
متن کاملThe impact of hematocrit on oxygenation-sensitive cardiovascular magnetic resonance
BACKGROUND Oxygenation-sensitive (OS) Cardiovascular Magnetic Resonance (CMR) is a promising utility in the diagnosis of heart disease. Contrast in OS-CMR images is generated through deoxyhemoglobin in the tissue, which is negatively correlated with the signal intensity (SI). Thus, changing hematocrit levels may be a confounder in the interpretation of OS-CMR results. We hypothesized that hemod...
متن کاملHematocrit distribution and tissue oxygenation in large microcirculatory networks.
OBJECTIVE Oxygen tension in the brain is controlled by the microcirculatory supply of RBC, but the effect of non-Newtonian blood flow rheology on tissue oxygenation is not well characterized. This study assesses different biphasic blood flow models for predicting tissue oxygen tension as a function of microcirculatory hemodynamics. METHODS Two existing plasma-skimming laws are compared agains...
متن کاملOptimal hematocrit: a Procrustean bed for maximum oxygen transport rate?
PHYSIOLOGICAL SYSTEMS are characterized by multiple interdependent components that collectively subserve various processes and functions. In seeking better understanding of the performance of such complex systems, we must identify and evaluate alternative ways and operating schemes, comparing their predicted performance with goals or objectives of interest. Optimization entails selecting a bett...
متن کاملThe optimal hematocrit increases during exercise.
TO THE EDITOR: We appreciate the approach of Drs. Stark and Schuster (13) to elaborate a systematic foundation of the optimal hematocrit concept on physics. However, some corrections and additional information are necessary. It is important to note that the empirical description of Pries et al. (7)—in contrast to the theoretical approaches for bulk viscosity—is based on experiments for tube flo...
