Under anesthesia, vitals are charted at fixed intervals (e.g. every 5 minutes). A start time plus repeated interval steps builds the monitoring timeline automatically.
The example
Start 09:00, every 5 min.
| A | B | |
|---|---|---|
| 1 | Item | Value |
| 2 | 09:00 + 5min×3 | — |
| 3 | Reading 3 | → 09:15 |

How it works
How it works:
- Convert the interval to a day fraction: minutes ÷ 1440.
- Multiply by the reading number and add to the start time.
- Fill down to build the whole monitoring timeline automatically.
- Flag a missed reading if the actual chart time exceeds the expected + tolerance.
Educational use only — not veterinary or medical advice. Dosing, fluid rates, and protocols must be set and verified by a licensed veterinarian for the individual patient. Always double-check against the drug label and a current formulary.

Pitfalls & errors
1440 minutes/day. Convert intervals to day fractions for time math.
Times are fractions. Excel stores time as a fraction of a day.
Not advice. Monitoring protocol is set by the veterinary team.
