Intraoperative fluid management shouldn't take a scratch pad. The Fluids Calculator gives you the whole picture from the patient's weight — a guided strategy for the case in front of you, and the working numbers to run it.
It opens with the question that actually changes your plan: is the patient likely to lose more than 500 mL of blood or have major fluid shifts? Answer it and you land on the right approach — a modest fixed volume for routine cases, or zero-balance and goal-directed targets for the big ones — each with its numbers spelled out.
For the maintenance plan, the 4-2-1 math is already done: a clear 'give this hour' figure up top, then maintenance, NPO deficit, and surgical loss broken out, with running totals for the first three hours you can tap between.
And the reasoning travels with every number:
- A guided yes/no decision flow that routes to fixed-volume, zero-balance, or goal-directed therapy
- The 4-2-1 maintenance rate, NPO deficit, and hour-by-hour running totals from the patient profile
- Surgical-loss guidance by case type, so you know what to dial in
- A one-tap rationale on every screen — the why behind each number, and why fixed-volume is discouraged in adults
It's the difference between recalling the formula mid-case and just reading the answer.
