Cold and mottled skin (livedo reticularis), especially extremities, due to insufficient perfusion of the skin The severity of hemorrhagic shock can be graded on a 1–4 scale on the physical signs. The shock index (heart rate divided by systolic blood pressure) is a stronger predictor of the impact of blood loss than heart rate and blood ...
