Case 5: Fluid Volume Calculations


Maintenance = [(30 x 4.8) + 70] = 214 ml/day

Replacement of dehydration deficit:

English Calculation
0.10 x 10.5 lb = 1.05 lb of weight loss from dehydration
1.05 lb x 454 ml/lb = 477 ml

OR

Metric Calculation
0.10 X 4.8 X 1000 = 480 ml
Correction of 80% of dehydration deficit in the first 24 hours:
0.80 x 480 ml = 384 ml

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

214 ml + 384 ml = 598 ml (approximately 24.9 ml/hour)
