The Stewart Approach for Analysis of Acid-Base Disturbances in Patients With Chronic Respiratory Failure

The Stewart approach for analysis of acid-base disturbances in patients with chronic respiratory failure.

We read with great interest the article by Guérin and colleagues, in the November 2010 issue of RESPIRATORY CARE,1 describing analysis of acid-base disorders with the Stewart method versus the conventional approach in patients with chronic respiratory failure in stable or unstable respiratory condition. Unfortunately, we find several aspects of the analysis to be rather misleading. First, accor...

Analysis of acid-base disorders in patients with chronic respiratory failure.

In a recent paper published in your prestigious journal, Guérin et al1 examined the acid-base disorders in a cohort of patients with chronic respiratory failure. Although I appreciated their contribution of case studies and statistical analysis, I am in partial disagreement with some of their conclusions. Guérin et al stratified the patients on the basis of stable versus unstable condition and ...

Quantitative analysis of acid-base disorders in patients with chronic respiratory failure in stable or unstable respiratory condition.

BACKGROUND The Stewart approach theorizes that plasma pH depends on P(aCO₂), the strong ion difference, and the plasma total concentration of non-volatile weak acids (A(tot)). The conventional approach measures standardized base excess, bicarbonate (HCO₃⁻), and the anion gap. OBJECTIVE To describe acid-base disorders with the Stewart approach and the conventional approach in patients with chr...
