Intake and output calculator
Intake and output calculator
A timed intake and output chart with a running balance on every line, printed with its totals — the sheet a shift hands over rather than a single net figure.
How this is calculated
Each line adds its intake and subtracts its output from the balance carried down from the line above. The totals are the sums of the two columns, and the closing balance is intake minus output across the whole chart.
- The running balance follows the order of the lines, not the clock. If a line is entered late, re-enter the chart in time order so the balance at each point reads correctly.
- The sheet holds the lines you typed and nothing else. It is not a fluid-order chart and does not compare the balance with a prescribed target; that comparison belongs to the clinical record.
- This page does the arithmetic and prints the unit beside every answer. It has no patient in front of it: it does not diagnose, does not choose or change a treatment, and does not replace the prescription, protocol or formulary you are working under. It has not been reviewed by a clinician for use in care, so treat it as a check on your own working — confirm the figure with an independent calculation and a qualified clinician before it is acted on.
A timed chart with a running balance on every line and totals at the foot, printed as a sheet a shift can hand over — the version of a fluid balance that follows the clock.
The running balance follows the order of the lines
Each line adds its intake and subtracts its output from the balance above it, so the column shows what the balance was at that point in the chart. That only reads correctly if the lines are in time order; a line entered late should be re-entered in sequence rather than appended to the bottom.
The printed sheet carries the lines you typed, the totals and the closing balance. It does not carry a prescribed target or a fluid order, because it cannot know either, and it does not compare the balance with one.
Questions readers ask
Is the chart saved anywhere?
No. It exists in the browser tab until the page is closed, and the printed sheet is produced from your own printer. Transcribe it into the record the facility keeps if it is to become part of the patient file.
How is this different from the fluid balance page?
That page totals intake and output by category and gives one net figure. This one keeps the clock, gives a balance after every line and prints a timed chart. They answer different questions and neither replaces the facility record.
