1
ECMO management involves complex decisions, with ongoing debates about the appropriate haemoglobin threshold for packed red blood cell transfusion.
-
2
Blood viscosity and rheological properties significantly influence oxygen delivery, complicating the relationship between transfusion and patient outcomes.
-
3
Historical transfusion practices for ECMO patients have shifted from a standard of 10 g/dL to more liberal and conservative strategies, reflecting evolving evidence.
-
4
Studies indicate that transfusion benefits may only occur when haemoglobin levels drop below critical thresholds, particularly in VA-ECMO and VV-ECMO patients.

Current guidelines from international societies on ECMO transfusion thresholds remain inconclusive, highlighting the need for clearer recommendations.
