The traditional view that tachycardia and hypotension accompany hemorrhagic shock following injury has been challenged. This is particularly true at extremes of age. Shock index (SI) may be an alternative indicator of life-threatening bleeding after injury. Because age negatively impacts physiological reserve, we hypothesized that age multiplied by SI (Age x SI) would be a better predictor of 48 h mortality (48 MORT) compared to heart rate (HR), systolic blood pressure (SBP), or SI.
