Data management Low-throughput machines display results on screen and may have a connect printer. For testing facilities where throughput is important, data management software and interface con- nectivity become important as well.
The GEM Premier line has real-time wireless upload capability, and GEMweb® Plus Custom Connectivity allows access and control from any networked PC or Gem Premier 4000 analyzer.
Analyzers from ITC have interface con- nectivity through RALS®-Plus, Aegis POC™, PrecisionWeb®/SYBASE®, and TELCOR QML®, and a data management system through Hemochron® Report Maker.
Operating costs The purchase price and the device warranty are important considerations in selecting an analyzer. Once an instrument is selected, op- erating costs such as the cost of reagents, the maintenance schedule, and the time required for recalibration come into play.

The Stat Profile pHOX adds hematocrit and hemoglobin; the Stat Profile pHOX Plus adds glucose, sodium, potassium, and chloride or ionized calcium; the Stat Profile pHOX Plus C adds chloride and ionized calcium; the Stat Profile pHOX Plus L adds lactate; and the Stat Profile pHOX Ultra adds ionized magnesium.
• OPTI Medical Systems: OPTI R and OPTI CCA-TS2 analyzers. The OPTI R measures pH, CO2
, pO2 , total hemoglobin, SO2 , sodium,
potassium, and ionized calcium, and the OPTI CCA-TS adds glucose and urea nitrogen.
• Radiometer America Inc. (www.
radiometeramerica.com): ABL80 FLEX, ABL90 FLEX, and ABL800 FLEX analyzers. The ABL80 FLEX and ABL90 FLEX are suitable for low-, medium-, and high-volume testing sites. The ABL80 FLEX measures pH, pCO2
, pO2 ,
hematocrit, electrolytes, metabolites, and co-oximetry. The ABL90 FLEX measures pH, pCO2
, pO2 , hemoglobin, electrolytes,
metabolites, and co-oximetry. The ABL800 FLEX is the largest of the three analyzers and is suitable for medium- to high-volume testing sites and measures pH, pCO2
, pO2 ,
hemoglobin, electrolytes, metabolites, and co-oximetry.
• Roche Diagnostics: cobas b 123 POC and cobas b 221 systems. The cobas b 123 POC system measures pH, pCO2
, pO2 ,

• Siemens Healthcare Diagnostics Inc. (
www.siemens.com): The RapidLab® 1200 systems measure pH, pCO2
, pO2 ,
electrolytes, metabolites, and co-oximetry. The RapidPoint® 300 system with the smallest footprint measures pH, pCO2
, pO2
(340, 350) and electrolytes, and hematocrit (350). The RapidPoint 400 systems measure pH, pCO2
, pO2 , electrolytes, metabolites,
and co-oximetry. The RapidPoint 500 systems have the same menu as the RapidLab 1200 systems.
Going forward As analyzers are becoming physically smaller with enhanced functionality, expanded menus, and integrated and automated quality control features, the expected continued focus of blood gas analysis technology is on testing at the point-of-care.
