alkalemia = pH >7.42<unk>  = pCO2 <38
May lead to Hypocalcemia, Hypokalemia
Check for a concurrent acid/base disturbance
always check for an AG
for every 10mm pCO2 <40, HCO3 expected to decrease by 1-3.5 mEq
if HCO3 < 24 - (40-pCO2)/10 x 2.5 (+/-1) then there is a superimposed primary metabolic acidosis
if HCO3 > 24 - (40-pCO2)/10 x 2.5 (+/-1) then there is a primary metabolic<unk> , or acute<unk>  without time for metabolic compensation
