2013, American Journal of Emergency MedicineCitation Excerpt :Although blood transfusion can restore both volume and oxygen transport capacity, it brings additional inflammatory, immune and biochemical issues, which has been clinically observed and associated with increased morbidity and mortality [22]. In an anemic condition, CO increases due to reduced blood viscosity and maintenance of tissue oxygenation and organ function at lower blood oxygen-carrying capacity [23]. Our experimental study shows that PEG-HSA increases CO, thus increasing oxygen delivery and compensating for the reduced oxygen carrying capacity.

2010, Critical Care ClinicsCitation Excerpt :Blood viscosity is inversely related to flow, so that for a given vessel diameter an increase in hematocrit will reduce blood flow exponentially.61 Very low hemoglobin concentrations impair the delivery of oxygen to tissues; paradoxically, a moderate decrease in hematocrit might improve oxygen transport by lowering blood viscosity.33,60,61,68 However, maintenance of blood viscosity is important in maintaining microvascular perfusion.69
