Adjusted Body Weight Calculator

Maintenance intravenous fluid or IV drip can be calculated based on adjusted body weight for obese patients (BMI >27.5).

To prevent fluid overload especially in Dengue patients.

Adjusted bodyweight (ABW) can be calculated using the formula:

ABW = IBW + 0.4 (actual weight – IBW)

Ideal bodyweight (IBW) can be estimated based on the following formula:

Female: 45.5 kg + 0.91(height in cm -152)

Male: 50.0 kg + 0.91(height in cm -152)

For non-obese patients:

1.2 to 1.5 ml/kg/hour.
