The reliability of the i-STAT clinical portable analyser

Summary The purpose of this investigation was to assess the reliability of the i-STAT clinical portable analyser and CG4+ cartridge measures of blood pH, partial pressures of O2 ( p O2 ) and CO2 ( p CO2 ), bicarbonate ([HCO3− ]), base excess (BE), total carbon dioxide ( T CO2 ), oxygen saturation (...

Description
Summary:Summary The purpose of this investigation was to assess the reliability of the i-STAT clinical portable analyser and CG4+ cartridge measures of blood pH, partial pressures of O2 ( p O2 ) and CO2 ( p CO2 ), bicarbonate ([HCO3− ]), base excess (BE), total carbon dioxide ( T CO2 ), oxygen saturation ( s O2 ) and blood lactate ([BLa− ]) at various exercise intensities. A comparison between [BLa− ] measured by the i-STAT and the Accusport lactate analysers during an intermittent treadmill run was also undertaken. The technical error of measurement (TEM%) at rest, at moderate (200 W) and maximal exercise ( V ˙ O 2   max ) was acceptable (
