“…Similarly, a greater specificity generated from the measurement of compensatory reserve indicated its superiority compared to the other vital signs and hemodynamic measures in the ability to identify patients who will not experience decompensated shock. The higher specificity of CRM reflects the failure of standard vital signs and hemodynamic measures alone to recognize the difference between individuals who are ‘good’ compensators from those who are ‘poor’ compensators [ 18 , 21 , 22 , 23 , 31 , 56 , 57 , 58 , 59 ]. Perhaps most striking is that standard vital signs and hemodynamic measurements have consistently been shown to lack sufficient accuracy as diagnostic tools to provide reliable clinical information [ 18 , 23 , 38 , 39 , 54 , 60 , 61 ].…”
