Trends of Hemoglobin Oximetry: Do They Help Predict Blood Transfusion During Trauma Patient Resuscitation?

BACKGROUND:A noninvasive decision support tool for emergency transfusion would benefit triage and resuscitation. We tested whether 15 minutes of continuous pulse oximetry–derived hemoglobin measurements (SpHb) predict emergency blood transfusion better than conventional oximetry, vital signs, and in
