<prompt> If blood gas analysis reveal pH 7.52, pCO 30 ; pO2 105. This will be compensated by ?Compensatory respiratory acidosisCompensatory respiratory alkalosisCompensatory metabolic acidosisCompensatory metabolic alkalosis  <response>: First stepDetermine whether it is acidosis or alkalosisIncrease in pH suggests alkalosisSecond stepLook at CO2 or HCO3- to determine the causeDecreased PCO2 suggests respiratory alkalosisRespiratory alkalosisRespiratory alkalosis occurs because CO2 is blown off in excess equation shifts to left and H conc. decrease which leads to alkalosis.Now the kidneys compensate for this alkalosis by excreting more HCOO3-. This shifts the equation to right thus H conc. decreases.
