We read with interest in the April 1993 issue of Chest the artide by Liss and Payne’ on “Stability of Blood Gases in Ice and at Room Temperature.” Although some authors would agree that the small changes observed in Pco , and pH when the arterial blood samples were kept at room temperature make it unnecessary to maintain arterial blood in ice if gas analysis is done within 30 mm, several commen...

In connection with the problem of the determination of the cardiac output by the use of ethylene (13), it seemed of interest to investigate further the nature of the forces which make the solubility of this gas 1% times as great in human blood as it is in water. The general problem of the nature of the factors which determine the solubility of gases in blood is of importance not only because of...

A consensus statement from the International Cerebral Palsy Task Force outlined essential criteria to define an acute perinatal hypoxic event; criteria included evidence of a metabolic acidosis in fetal umbilical arterial cord blood or in very early neonatal blood samples (pH < 7 and base deficit >12 mmol/l). Pathological fetal acidaemia may be correlated with an increased risk of neurological ...

The objective of this study was to find a relationship between blood gas parameters and thyroid hormoneactivity with ascites syndrome in broiler chickens exposed to cold temperature and receiving a high qualitydiet. One hundred and sixty one-day-old broiler chicks were randomly divided in two equal groups. Toincrease the incidence of ascites, chicks of group 1 were fed ad libitum with a higher ...

The gas chromatographic determination of volatile organic anaesthetic agents in blood and in respiratory gases is described. The analysis in blood is based on a head space technique. Sampling of inspired and end-tidal gases is carried out by means of a system including a gas sampling valve.
