 In the ED setting, there is a need to efficiently triage a patient and designate a disposition for appropriate treatment management and outcomes. Hemoglobin level is an accurate indicator that helps distinguish patients who need early blood transfusion and meet criteria for admission. Noninvasive technology, such as the SpHb device by Masimo, will assist with common goals in emergency medicine: to efficiently and accurately decrease wait times to treatment and disposition, screening patients who have difficult venous access, providing repeated sampling without causing iatrogenic blood loss linked to anemia, and offering an approach that may be used to develop an organized coherent therapeutic plan based on physiologic criteria for the emergency patient as heshe proceeds from the ED to the OR, the hospital general floor, and the ICU.
