Prior to exchange transfusion, the hemoglobin was 95 g/L (Table 1) and HbS quantified by HPLC was 66.4% (Figure 1), as a result of the recent blood transfusion. After this initial step, the Hb was 98 g/L and HbS was 57.2% (Figure 1). 12 hours after the RCE, the patient was afebrile, and the SPO2 was 83-88% on room air. The patient was afebrile, with oxygen saturation of 97-100% on room air (Figure 1), RR of 28-30/min and pulse rate of 90 bpm.
