If blood gas analysis reveal pH = 7.52, pCO = 30 ; pO2 = 105. This will be compensated by ?

First step Determine whether it is acidosis or alkalosis Increase in pH suggests alkalosis Second step Look at CO2 or HCO3- to determine the cause Decreased PCO2 suggests respiratory alkalosis Respiratory alkalosis Respiratory 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.
