and the identification of primary acid-base disorders was standardized in accordance with the eight possibilities proposed on the Siggaard-Andersen nomogram in 1963, which were further adjusted for altitude by P.E Paulev in 2005 [7, 10].
Details for the interpretation of arterial blood gases are out of the scope of this manuscript; it is recommended to refer to the article by Lasso JI, "Interpretation de los gases arteriales en Bogota (2.640 msnm.) basada en el nomograma de Siggaard-Andersen. Una propuesta para facilitar y unificar la lectura" .
In the 1960's, the Siggaard-Andersen
nomogram used this value to further explain the extent of the non-respiratory cause of a patient's abnormal pH.

P50, the P[o.sub.2] for a given blood sample at which the Hb is half-saturated, was calculated by the ABL725 software according to the method of Siggaard-Andersen
Ole Siggaard-Andersen, MD, PhD, is professor of clinical biochemistry at the University of Copenhagen in Denmark and is a former chair of the department of clinical biochemistry at Herlev University Hospital.
Siggaard-Andersen published a revision of his work he named the Van Slyke equation, which became widely known and was included in the software of many manufacturers of pH-blood gas equipment.
