<prompt> In a typical blood gas analyserOxygen tension will be overstimulated in hypothermiapH is a derived measurementStandard bicarbonate can be used to indicate the respiratory componentThe oxygen tension can be measured using Clarke electrode.  <response>: Oxygen tension falls with hypothermia. The pH electrode directly measure pH. The standard bicarbonate measured in sample titrated to pCO2 of 5.3 kPa, which eliminates respiratory component.
