<prompt> Lab values: pH 7.56, paCO2- 20, HCO3- 20 .Interpret?Respiratory alkalosis, uncompensatedRespiratory alkalosis, compensatedRespiratory alkalosis, paially compensatedMetabolic alkalosis, paially compensated  <response>: pH - 7.56 Alkaline PaCO2 - 20 low HCO3 - 20 low So this is Respiratory alkalosis PaCO2 by 20 mm Hg So HCO3 to be by 4x28 HCO3 to be bw 14 -18 HCO3 in question 20 pH-alkaline So respiratory alkalosis but paially compensated
