flow sheet
Meaning of flow sheet: A grid in the chart where the same measurement is written again and again, so a trend shows at a glance.
Definition of flow sheet
A flow sheet is a form within a medical record laid out as a grid, with the items being tracked down one side and successive times across the top, so repeated observations on one person sit side by side. Vital signs, fluid balance, wound checks and doses given are recorded this way. The purpose is to make change over time visible without reading through pages of notes.
How is it different from a flow chart?
Completely, despite the near-identical name. A flow chart is a diagram of boxes and arrows showing the order of steps in a process, and it belongs to a protocol rather than to a person. A flow sheet holds measured data about one individual and contains no arrows at all. Reference entries that define a flow sheet as a diagram of steps have simply merged the two terms, and the error matters because the documents live in different places and answer different questions.
| Document | What it holds | Belongs to |
|---|---|---|
| Flow sheet | Repeated measurements over time | One person's record |
| Flow chart | Steps and decision points | A process or protocol |
| Flow cytometry report | Cell marker measurements | A laboratory result |
Why does the layout matter?
Because comparison is the whole point. A gentle downward drift in blood pressure across a shift, or urine output falling hour by hour, is nearly invisible in prose entries written at intervals but obvious as a column of figures read downward. Electronic records keep the same arrangement and add automatic graphs for the same reason. Blank cells carry meaning too, since a gap records that an observation was not made, which narrative notes rarely reveal. The format has a matching weakness: a grid invites the previous value to be carried forward without fresh measurement, and an error entered once tends to persist down the column.
What sits alongside it in a record?
A chart mixes documents of several kinds, and knowing which is which speeds up reading it. Narrative notes carry reasoning and plans. Standing instructions such as a do-not-resuscitate order record a decision that applies until changed. Medicine administration records, growth charts in childhood, anticoagulation records and anesthetic records are all flow sheets in form, whether or not they carry the name, because each tracks the same variables repeatedly against time.

Hourly urine output was recorded on the fluid balance flow sheet.
Good to know
A flow sheet and a flow chart are unrelated documents: the sheet is a grid of repeated observations inside one person's record, while the chart is a diagram of the steps in a process.
