3. Treatment:
   i. pH < 7.6, asymptomatic (chloride-responsive assumed)
     a. volume depleted: give IV-NS and K+ (base amount of K+ on urine
        Cl-); see below.
     b. edematous but intravascularly depleted (CHF, nephrosis,
        cirrhosis):  give albumin to  intravascular volume if
        appropriate, replete K+ agressively, and consider Diamox (see
        below)
     c. volume expanded (rare): give KCl po or IV
  ii. pH > 7.6, symptomatic (chloride-responsive assumed)
     a. monitored bed
     b. NH4Cl or HCl IV
        1. 20-40 mEq/hr of 0.1 N or 0.15 N HCl through central line
           (NH4Cl can be given PO, but must be avoided in cirrhosis or
           renal failure because of NH3 buildup)
        2. 100 mEq H+ should  HCO3- by 7 mEq/L
        3. follow Q1H pH, pCO2, HCO3-
        4. stop when pH < 7.6 and asymptomatic
     c. Acetazolamide (Diamox)
        1. watch for  K+; must supplement with massive amounts KCl
        2. 250 mg IV Q8H
        3. stop when pH < 7.6 and pt. asymptomatic
  iii. non-chloride-responsive:  urinary Cl- > 20 mEq/l means not
     chloride-responsive (rare), so problem is probably primary
     hyperaldo, or severe lack of K+ leading to HCO3- loss; give plenty
     of K+,. and give large doses of Aldactone (spironolactone) to
     block aldo receptors.
