| Day | Mean systolic mmHg | Mean diastolic mmHg | Readings | AM count | PM count | Recorded coverage |
|---|---|---|---|---|---|---|
| 2 | 127 | 79 | 2 | 1 | 1 | Incomplete 2+ AM/PM coverage |
| 3 | 125 | 79 | 2 | 1 | 1 | Incomplete 2+ AM/PM coverage |
The summary is not a diagnosis or medication adjustment. A complete home monitoring protocol generally requires repeated morning and evening readings over several days; this worksheet displays missing sessions instead of certifying completion.

How to use Seven-Day Home Blood Pressure Diary
- Enter each cuff measurement as a separate row, with a day number from one to seven and AM or PM.
- The default excludes day one, reflecting the cited home-monitoring convention.
- Daily rows show how many accepted measurements were recorded and how many AM and PM readings are present.
Worked example
After discarding the example’s first day, mean pressure is 126/79 mmHg.
Formula, accuracy & limitations
Average each accepted systolic and diastolic reading separately. Optional day-one exclusion follows the stated diary convention. Daily summaries retain sample counts; unrecorded sessions are not invented.
The summary is not a diagnosis or medication adjustment. A complete home monitoring protocol generally requires repeated morning and evening readings over several days; this worksheet displays missing sessions instead of certifying completion.
The primary result is rounded to two decimal places. Calculation tables show up to four and supporting metrics up to six. Very small nonzero values use scientific notation. Display rounding is not fed back into the arithmetic.
Official source and method context ↗Keep systolic and diastolic paired
Enter each cuff measurement as a separate row, with a day number from one to seven and AM or PM. The systolic number must exceed the diastolic number. Several readings in one session remain separate measurements; they are not averaged into a single invented session before the overall calculation.
Decide whether day one belongs in the summary
The default excludes day one, reflecting the cited home-monitoring convention. Changing this setting recalculates both means and the accepted count. The excluded rows remain visible in the audit so you can explain why a displayed mean differs from an unfiltered spreadsheet.
Review coverage alongside the mean
Daily rows show how many accepted measurements were recorded and how many AM and PM readings are present. A diary with missing sessions can still have an arithmetic mean, but it is not presented as a completed seven-day protocol. Missing measurements never become zero blood pressure.
Use the diary as a discussion aid
Cuff fit, posture, rest and measurement conditions influence readings. This page does not classify hypertension, recommend an extra dose or authorise stopping treatment. The paired chart supports review of the actual entered values, while the table preserves the sample counts behind the summary.
Frequently asked questions
Why does the default leave out day one?
The cited home-monitoring convention discards the first day before taking the remaining mean. Switch it off if you need an all-recorded-readings comparison.
Do three readings in one session count once?
Each accepted row contributes one paired measurement to the overall means. The daily table also shows how many readings came from each AM and PM session.
Does a displayed mean prove I completed seven days?
The coverage table reports the days and sessions actually entered. A mean can be calculated from an incomplete diary without claiming protocol completion.
Can the calculator tell me to change medication?
The page does not diagnose hypertension or adjust treatment. It organises supplied readings and their arithmetic.
