TBW is what % of total body weight?

TBW is 50% TBW in women, 60% in men


Breakdown of TBW

2/3 ICF
1/3 ECF


What is the breakdown of ECF?

1/4 plasma, 3/4 interstitial fluid


At what rate should fluids be repleted in a hypovolemic patient?

BOLUS over 1st over is 20 cc/kg. Over next 8 hrs give maintenance rate + 1/2 remaining calculated deficit. Over next 16 hrs give maintenance rate + the other 1/2 remaining calculated deficit.


Super large amounts of NS can cause what metabolic state?
