Bland-Altman agreement analysis (26,27) was performed for pH, pC[O.sub.2], p[O.sub.2], HC[O.sub.3], BE, and [O.sub.2] saturation between each pair of ABG, pVBG, and cVBG to evaluate agreement between the two blood gas
testing and related measurements: National recommendations on behalf of the Croatian Society of Medical Biochemistry and Laboratory Medicine.
All samples were collected from the patients after 12 hours of initiation of mechanical ventilation and the samples were analysed using a point-of-care blood gas
analyser, Eschweiler BGA Plus E Combisys II.
Calibration standard of the common brand of arterial blood gas
analyzers are documented in the Clinical and Laboratory Standard Institute.
In this study, any abnormality in blood gas
analysis including low pH, high PaC[O.sub.2], low Pa[O.sub.2], and high Pa[O.sub.2] was considered as "disease/condition", and Sp[O.sub.2] value by pulse oximetry was considered as "test".
The researchers concluded: "Analysis of absolute accuracy showed a smaller bias but slightly larger standard deviation for SpHb than the blood gas
analyzer when compared to the hematology analyzer reference.
All the determinations were performed using a RAPIDLab[R] 1200 Blood Gas
Analyzer (Siemens Healthcare Diagnostics Inc., Deerfield, IL, USA) according to the manufacturer's instructions.
Specifically, Sysmex will provide a quality control service for biochemical analyzers and on-site repair and inspection service for blood gas
For 10 days, whole-blood potassium was measured with an AVL Omni 6 blood gas
analyzer (Roche Diagnostics) in all arterial blood-gas specimens received by the laboratory.
The Danish blood gas
analysers developer Radiometer A/S said today (19 November) it had received a renewed purchasing contract from the US hospital products purchasing organisation Novation.
For example, Malcolm said, blood gas
analysis devices are calibrated using barometers that contain mercury.
In addition to a tutorial, the software includes a computerized blood gas
calculator for determination of acid-base disorders and A-a gradients.
