WebIntravascular hemolysis results in release of cell free hemoglobin, RBC stroma, and nonstroma proteins. Free hemoglobin binds nitric oxide (NO) at rate 1000 times that of RBC. Hemoglobin scavenging leads to decreased bioavailability of NO and thus vasoconstriction and alterations in capillary response to hypoxia. highest tax states for retirement
