<prompt> A person presents with the following parameters. pCO2 : 30 mm Hg, PO2 :105 mm Hg, pH : 7.45. He is having partially compensated -Metabolic acidosisMetabolic allcalosisRespiratory 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.
