Abstract:
The Corning 175, a fully automatic new blood-gas analyzer, was tested and compared with manual analyzers (Eschweiler-Radiometer). The precision was evaluated by means of tonometered bloods and precision gas mixtures. With the Corning 175 four parameters are measured: pH, PCO2, PO2, barometric pressure, and four computed: HCO3-, BE, oxygen content, oxygen saturation. These are automatically corrected for patient hemoglobin and temperature. A microprocessor controls the sequencing of all operations during the calibrations and the measurements and continuously checks the performances of the electrodes and the entire system. The operator part is limited to the introduction of blood. The advantages and the fiability of the automatism in clinical routine are described.
