PerfWeb 105 Day 2 focuses on the impact of hemoglobin on oxygen delivery (DO₂), a fundamental concept in perfusion practice. This session examines the relationship between hemoglobin concentration and systemic oxygen transport, with direct implications for patient safety and clinical decision-making during cardiopulmonary bypass. Designed for practicing perfusionists, board exam candidates, and healthcare professionals, the program blends theory with real-world applications in perfusion. Learning Highlights: The role of hemoglobin in oxygen delivery (DO₂). Physiological principles behind oxygen transport, Strategies to optimize DO₂ during bypass, Clinical relevance of hemoglobin levels in perfusion outcomes.
