Blood Gases: Haemoglobin, Base Excess and Maldistribution

Prediction of Respiratory Morbidities in Late Preterm Neonates Using Cord Blood Arterial Lactate and Base Excess

Background: Late preterm neonates may have the external appearance and behavior similar to their counterparts.However, they are susceptible to various neonatal morbidities , due to their physiological and metabolical immaturity.To assess the correlation between cord blood arterial lactate levels and base excess with the development ofrespiratory distress in late preterm neonat...

Arterial blood gases and acid-base balance in normal children.

Robinson (1) studied the effect of age on the arterial blood gases and the acid-base balance of normal males from 5 to 91 years of age. In addition to the well known increase in oxygen combining capacity which occurs during childhood and adolescence, Robinson found moderately lower mean values for hemoglobin saturation in adults above 40 years of age, and slightly higher mean values for arteria...

The accuracy of calculated base excess in blood.

Most equations used for calculation of the base excess (BE, mmol/l) in human blood are based on the fundamental equation derived by Siggaard-Andersen and called the Van Slyke equation: BE = Z x [[cHCO3-(P) - C7.4 HCO3-(P)] + beta x (pH -7.4)]. In simple approximation, where Z is a constant which depends only on total hemoglobin concentration (cHb, g/dl) in blood, three equations were tested: th...

Determination of base excess in umbilical cord blood at birth: accessory or excess?

Blood Reaction and Blood Gases in Pneumonia.

Peabody in 1912 (1) published a paper on the metabolism in pneumonia, in which he reviewed the previous literature and studied among other factors the blood gases and acid-base balance. Since Peabody, a number of other investigators have studied the blood gases and the question of the existence and importance of acidosis in pneumonia. The present paper is a report of observations on these subje...
