<prompt> A person presents with following parameters PCO2 30 mm of Hg, PO2 105 mm of Hg, pH 7.45 is having partially compensated -Metabolic acidosisMetabolic alkalosisRespiratory acidosisRespiratory alkalosis  <response>: Increase in pH suggests alkalosisPCO2 is decreased, this suggests respiratory alkalosis.The metabolic component cannot be evaluated as data is not provided. So the diagnosis seems to be respiratory alkalosis.
