Which intervention is most effective in increasing the oxygen-carrying capacity of blood in a patient with severe anemia and decreased hemoglobin levels during critical care transport?
Application of continuous positive airway pressure (CPAP)
Use of vasopressors
Transfusion of packed red blood cells (PRBCs)
Administration of crystalloids
In patients with severe anemia and decreased hemoglobin levels, transfusing packed red blood cells (PRBCs) is the most effective intervention to increase the oxygen-carrying capacity of the blood. Hemoglobin within red blood cells is responsible for transporting oxygen, so increasing the number of red blood cells directly enhances the blood's ability to deliver oxygen to tissues. Administering crystalloids or vasopressors can be supportive but do not address the underlying issue of insufficient hemoglobin.
