Vital signs indicate the presence of bleeding only after large amounts of blood have been lost, with high morbidity and mortality. The Shock Index (SI) is a hemorrhage indicator with a cut-off point for the risk of bleeding at 0.9. The aim of this study is to assess whether a cut-off of≥0.8 is more sensitive for detecting occult bleeding, providing for early initiation of therapeutic maneuvers. ⋯ An SI cut-off point≥0.8 is more sensitive than≥0.9 and allows for earlier initiation of resuscitation maneuvers in patients with occult active bleeding.
