Assessing the ABL 500 blood gas analyser
The ABL 500 blood gas analyser from Radiometer has cordless electrodes and does not use a humidifier for calibrating gases. During the evaluation of the analytical performance of this instrument, the problem of p0(2) accuracy was approached by comparing the values obtained with two kinds of tonometry (film and bubble). An acceptable level of imprecision was demonstrated for all measured paramet...
متن کاملAccuracy of the i-STAT bedside blood gas analyser.
The performance of the i-STAT portable clinical analyser for measuring blood gases and pH was evaluated with reference to a conventional blood gas analyser (ABL520 Radiometer). Ninety-two samples from the routine blood gas analysis laboratory were chosen according to a wide distribution of partial pressure of carbon dioxide (Pa,CO2), partial pressure oxygen (Pa,O2) and pH and then analysed. All...
متن کاملUnderstanding Software Connector Compatibilities Using a Connector Taxonomy
Software systems of today are frequently composed from prefabricated, heterogeneous components that provide complex functionality and engage in complex interactions. Software architecture research has revealed the importance of component interactions on our ability to perform software composition. Various development organizations have found interaction mismatches to be both difficult and a cor...
متن کاملValidation of a photoacoustic gas analyser for the measurement of functional residual capacity using multiple-breath inert gas washout.
BACKGROUND The respiratory mass spectrometer is the current gold-standard technique for performing multiple-breath inert gas washout (MBW), but is expensive and lacks portability. A number of alternative techniques have recently been described. OBJECTIVES We aimed to validate, using an in vitro lung model, an open-circuit MBW system that utilises a portable photoacoustic gas analyser, with su...
متن کاملDevelopment and evaluation of an instant column connector for capillary gas chromatography
Coupling capillary columns in gas chromatography (GC) is not an operation that is only relevant for the users of the most advanced capillary GC methods. Simple single-column separations can also benefit from a properly selected and installed pre-column. Pre-columns connected upstream of the main column can increase the life-time of the column, efficiently refocus the analyte bands to result in ...
