 Blood Gas and Chemistry Analyzer
The Blood Gas and Chemistry Analyzer is an electronic instrument which is used to analyze
whole blood samples (measuring blood gases, electrolytes, metabolites, and hematocrit). The
analyzer can:
 Scan bar codes of test cartridges, calibrant fluid packs, controls, patient and operator ID,
etc.
 Identify the types of test cartridges.
 Control the flow of fluids.
 Maintain sample temperature at 37°C.
 Measure the ambient barometric pressure and ambient temperature.
 Measure electrical signals generated by chemical sensors and biosensors.
 Analyze and display the concentrations of analytes in whole blood samples.
 Transmit test results to the Data Management System (DMS).
