The causes of this are the same as the causes of NAGMA (see also EMCrit — Acid Base in the Critically Ill – Part I). We don’t have the albumin so we can’t calculate a corrected anion gap or strong ion gap, but we …

WebStewart proposed a more comprehensive measure of acidosis based on the strong ion difference (SID) (SID = Na + K + Mg + Ca - CL - lactate [mEq/L]). We compared operating characteristics of BD, anion gap (AG), and SID in identifying major injury in emergency department (ED) trauma patients. Methods: This was a retrospective review. Major injury ... WebJun 8, 2015 · SID - the strong ion difference A TOT - the total weak acid concentration PaCO 2 Thus, changes in any of the independent variables can cause a change in pH and HCO 3-, i.e. acidosis and alkalosis. All the independent variables must be known to calculate the dependent variables Thus, acid-base disorders can be classified as:
WebMay 2, 2016 · In the Stewart approach, the 3 independent controllers of acid-base status in body fluids are the partial pressure of CO 2, the strong-ion difference (SID), and the total … WebSID is the difference between strong cations and strong anions in solution. “Strong” denotes how completely a species dissociates in a particular solution.
