“…In its evolution, an SI > 0.9 was proposed as an indicator of impending hemorrhagic shock (58,60,61). Indeed, there is compelling evidence suggesting that SI is more sensitive than either HR or SBP alone as an early predictor of hemorrhage (60,62,63), massive transfusion (64), morbidity (58), and mortality in geriatric patients (59,61). Based on the SI threshold of 0.9, doctrine would indicate that Group 2 would be considered at higher risk for developing shock than Group 1.…”

Shock is deadly and unpredictable if it is not recognized and treated in early stages of hemorrhage. Unfortunately, measurements of standard vital signs that are displayed on current medical monitors fail to provide accurate or early indicators of shock because of physiological mechanisms that effectively compensate for blood loss. As a result of new insights provided by the latest research on the physiology of shock using human experimental models of controlled hemorrhage, it is now recognized that measurement of the body's reserve to compensate for reduced circulating blood volume is the single most important indicator for early and accurate assessment of shock. We have called this function the "compensatory reserve," which can be accurately assessed by real-time measurements of changes in the features of the arterial waveform. In this paper, the physiology underlying the development and evaluation of a new noninvasive technology that allows for real-time measurement of the compensatory reserve will be reviewed, with its clinical implications for earlier and more accurate prediction of shock.

“…Over time, the SI has been linked to many variables in an attempt to assess patients' clinical conditions more accurately. A connection has been found between SI and (1) length of hospital stay in intensive care units (ICUs) (McNab et al , ), (2) days of invasive ventilation (McNab et al , ), (3) need for transfusions (Vandromme et al , ; McNab et al , ; DeMuro et al , ), (4) septic complications (Berger et al , ) and (5) death in patients with pulmonary embolism (Toosi et al , ) and septic shock (Yussof et al , ). The SI is evaluated both at the trauma scene (pre‐hospital SI‐pH) and in the emergency room (SI‐ER).…”

“…The SI (defined as heart rate divided by systolic blood pressure) has previously shown promise in identifying the severity of hemorrhagic shock as well as other forms of shock [12,13]. Their current study examines the ability of the index to predict the need for transfusion.…”

The rapid and accurate prediction of the need for massive transfusion in bleeding trauma patients remains a challenge. Various models have been proposed to anticipate massive transfusion with variable success. The current study by Mutschler and colleagues proposes four classes of shock as defined by the Shock Index and examines its ability to predict the need for massive transfusion. This model demonstrates promise as a practical tool in acute decision-making for transfusion after injury.
