The Relationship Between Mortality and Hemoglobin Levels in Intensive Care Patients with Acute Respiratory Distress Syndrome

Objective: Low hemoglobin levels are associated with an increased risk of mortality in intensive care unit (ICU) patients. The underlying reason is due to the limitation in oxygen delivery to the tissues caused by a reduction in the number of oxygen carrying erythrocytes. This study aimed to examine the relationship between decline in hemoglobin level (DHgb=Admission hemoglobin -nadir hemoglobin), nadir hemoglobin levels (NdrHgb; the lowest hemoglobin value during ICU stay) and mortality in COVID ARDS patients admitted to ICU.
