Pitfalls in Interpreting Umbilical Cord Blood Gases and Lactate at Birth
Acid-base status in umbilical cord blood is an objective measure of the fetus’ exposure to and ability to handle hypoxia. The objective of this thesis was to clarify some of the methodological pitfalls in interpreting umbilical cord blood gases and lactate values at birth. Study I pinpoints the …

The respiratory distress syndrome of the newborn : studies of blood gases and acid/base balance with the object of formulating principles of treatment
Respiratory failure accounts for a large, if not the largest, percentage of deaths during the first 48 hours of life. During the last ten years a great deal of research has been devoted to this early respiratory failure. The syndrome has been known by different names at different times; hyaline …

Cardiovascular Fitness of Horses Conditioned by Treadmill Work
… volume, lactic and pyruvic acid concentrations, blood gases and blood pH. In all three experiments, the SET consisted of a rest period and warm-up walk followed by a period of trotting (11.4 to 12.1 kph) and a six minute standing recovery period on the treadmill. Parameters were measured at rest …
