Background Pulse-oximetry (Spo2) widely uses as a help tools for therapeutic interventions in the pediatric intensive care units (PICU). The aim of this study was to evaluate the validity of Spo2 in measuring of oxygenation index (OI) in children. Materials and Methods In a descriptive analytical study, 100 patients who were admitted to PICU Tabriz Children's Hospital were studied. Oxygenation ...

42 Abstract Background: Blood gas analysis is a widely used procedure. In clinical practice, the physicians may not always have a blood gas analyzer in their proximity. Not infrequently, blood gas samples are stored in a fridge or on ice and read retrospectively. Continued anaerobic and aerobic metabolism in the blood may alter blood gases in the interval between drawing arterial blood and its ...

The objective of this study was to determine the effects of diets having different fermentability on blood gases, blood metabolites and ruminal fermentation parameters in Holstein dairy cows. Four multiparous Holstein dairy cows (665 ± 25 kg BW, 170 ± 7.0 DIM and 15±1.5 kg of milk yield), fitted with rumen cannulae, were used in a 4×4 Latin Square design with 28-d periods. Corn starch and sucro...

The dctcrmination of anesthetic gases in blood taken from patients during anesthesia has been reported in several instances (l-3). In each case, however, reservation has been made as to the accuracy of the results because of errors in the vacuum extraction method. The principal source of error has been that the volume of gas determined was not corrected for unextracted gas. This technical diffi...

Although the naturally occurring atmospheric noble gases He, Ne, Ar, Kr, and Xe possess great potential as tracers for studying gas exchange in living beings, no direct analytical technique exists for simultaneously determining the absolute concentrations of these noble gases in body fluids in vivo. In this study, using human blood as an example, the absolute concentrations of all stable atmosp...

INTRODUCTION In chronic alveolar hypoventilation, previous studies of selected patient groups have shown that nocturnal home mechanical ventilation (HMV) may result in improvements in chronic blood gas disturbances during daytime spontaneous breathing. We wished to examine the effects of this treatment in a large sample of non-selected patients prospectively followed up, in a national multicent...
