Transfusion Thresholds and Anemia Insights

This chapter examines the challenges of blood transfusions, emphasizing the benefits of restrictive transfusion strategies highlighted by studies like the TRIC trial. It explores the body's physiological reserves during acute anemia, including the effects of isovolemic hemodilution on cardiac parameters and oxygen delivery capabilities. The discussion also addresses the relationship between blood viscosity and systemic vascular resistance, providing insights into how the body manages low hemoglobin levels.
