Table 2 Restrictive red blood cells transfusion criteria as per institutional guidelines

RBC transfusion threshold	Patient population
Hemoglobin ≤ 7 g/dL	Hemodynamically stable patients on medical floors and ICU
Hemoglobin ≤ 8 g/dL	Hemodynamically stable patients on medical floors and ICU with preexisting CVD1
Hemoglobin ≤ 10 g/dL	Active bleed2
Hemoglobin ≤ 10 g/dL	Down-trending hemoglobin3

¹Pre-existing cardiovascular disease is defined as past history of at least one episode of angina irrespective of percutaneous coronary intervention.

²Active bleed is defined as documented witnessed bleed by nurse/physician or hemodynamic instability attributed to bleeding.

³Down-trending hemoglobin is defined as fall in hemoglobin more than or equal to 2 g/dL.

CVD: Cardiovascular disease; ICU: Intensive care unit.
