What the two numbers mean

Blood pressure readings have a systolic number, measured as the heart beats, and a diastolic number, measured between beats. Both use mmHg. A home reading depends on the monitor, cuff fit, and measurement technique; a clinician interprets your pattern in the context of your health.

A blood pressure log brings together the upper and lower numbers, when they were measured, and the circumstances of the measurement. The website cannot take a reading: you need an appropriate monitor and a measuring routine agreed with your care team.

This hub helps you keep the original readings intact. The guide explains paired readings and record quality; the browser log and paper sheet keep the values in separate columns. Use the appointment notes tool to identify your device, missing sessions, and questions about technique or the schedule. Your clinician decides how the results should be interpreted.
