Blood gas and electrolytes analyzer measures pH, PCO2, PO2, Na+, K+, Ca++, and Hct and calculates additional parameters: Thgb, pH(T), PCO2(T),PO2(T), TCO2, HCO3, BEb, BEecf, SBC, %SO2c, CtO2, A-aDO2, RI, Ca++ (7.4). Fits both syringe and capillary samples without adaptors. The sample probes self-wiping feature provides convenience, sample integrity and user safety. Sample Type: Whole blood (Sample Source: arterial, mixed venous, venous) Sample Size: 120 µL Syringe mode/95 µL Capillary mode All components are combined into three simple modules, easily accessible by the user. Routine maintenance is limited to the replacement of electrodes and a single pump tube. Self-contained Reagent Module contains liquid calibrators and collects all waste. Calibration is automatic and on-demand. Simple menus guide the user through analyzer operation. Bar code scanner option permits rapid, accurate input of patient, operator and QC data. The software allows selection of desired options, including: " Language " Quality Control limits " Reference limits " Operator ID" Correlation with other methods " Patient data. " The quality control program calculates and stores complete statistics for the last 31 days of quality control results at each of three levels. A printed Levey-Jennings chart visually identifies trends. " The data management program compares all patient results with ranges stored in memory and flags out-of-range results. Results are stored in memory for up to 64 patients. " All necessaries information can be entered using the digital numeric keypad with graphic display and integrated with patient results. Measured and calculated results are displayed and printed on the 27 column thermal line printer. " Compact, portable format with a small footprint to save space (Size 37cm W x 32cm H x 18cm D, weight 7.7 kg with Reagent Module).
