Case 1: Fluid Volume Calculations


Maintenance = [(30 x 10) + 70] = 370 ml/day

Replacement of dehydration deficit:

English Calculation
0.07 x 22 lb = 1.54 lb of weight loss from dehydration
1.54 lb x 454 ml/lb = 699 ml

OR

Metric Calculation
0.07 X 10 X 1000 = 700 ml
Correction of 80% of dehydration deficit in the first 24 hours:
0.80 x 699 ml = 559 ml

Total fluid requirement for dehydration plus daily maintenance for the first 24 hours:

370 ml + 559 ml = 929 ml (approximately 39 ml/hour)
