Blood Acid-Base Alignment Nomogram: Scales for pH, pCO2, Base Excess of Whole Blood of Different Hemoglobin Concentrations, Plasma Bicarbonate, and Plasma Total-CO2

Andersen, O. Siggaard·1963·Scandinavian Journal of Clinical and Laboratory Investigation

Abstract

The blood acid-base status comprises the pH, pCO2 and base excess values.The alignment nomogram includes scales for these values together with scales for bicarbonate and total-CO2 of plasma.The nomogram is especially useful for calculation of base excess after direct measurement of pH, pCO2 and hemoglobin concentration. The nomogram is also useful for calculation of both pCO2 and base excess after direct measurement of pH, total-CO2 of plasma and hemoglobin concentration.The standard bicarbonate can also be calculated from the nomogram.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
