Two variations of the shock index may provide additional insights, especially in trauma patients..
Parameters:
(1) heart rate in beats per minute
(2) systolic blood pressure in mm Hg
(3) diastolic blood pressure in mm Hg
(4) age in years
mean arterial blood pressure =
= ((systolic blood pressure) + (2 * (diastolic blood pressure))) / 3
shock index =
= (heart rate) / (systolic blood pressure)
modified shock index =
= (heart rate) / (mean arterial blood pressure)
age shock index =
= (age in years) * (shock index)
