The Holliday-Segar formula estimates daily maintenance fluid requirements based on which parameter?

Explanation:
Maintenance fluid needs are driven by body size, and the Holliday-Segar method uses weight in kilograms to estimate daily needs. It assigns fixed amounts of fluid per kilogram across weight bands (for example, a higher amount per kg for the first 10 kg, a lower amount for the next 10 kg, and an even smaller amount for every kilogram over 20 kg). This weight-based approach yields the total daily maintenance fluids, which can then be converted to an hourly rate if needed. Height, age, or activity level aren’t the primary inputs for this calculation, so the key parameter is weight.
