# Home Blood Pressure Monitoring: A Complete Guide

> Why home blood pressure monitoring matters, how to do it accurately, what the numbers mean, and where a home monitor fits alongside your doctor's care.

High blood pressure (hypertension) is often called a "silent" condition because it usually has no symptoms, yet it's one of the most important risk factors for heart attack, stroke, and kidney disease. Checking your blood pressure at home — between doctor visits — is one of the most useful things you can do to understand and manage it.

<Note>
  A home blood pressure monitor is a tracking tool, not a diagnosis. Hypertension is diagnosed and treated by a clinician using readings over time. Never start, stop, or change blood pressure medication based on home readings alone.

## Why monitor blood pressure at home?

Blood pressure changes constantly throughout the day, so a single reading in a clinic is only a snapshot. Home monitoring captures a fuller, more representative picture and can reveal patterns a once-a-year office visit would miss — including [white-coat and masked hypertension](/blood-pressure/white-coat-hypertension). Major medical organizations now encourage home monitoring because the data helps clinicians make better decisions and helps patients stay engaged in their own care.

## What do the numbers mean?

Blood pressure is written as two numbers, like 120/80 mm Hg. The top number (systolic) is the pressure as your heart beats; the bottom number (diastolic) is the pressure between beats. Both matter — see [what a normal reading looks like](/blood-pressure/normal-blood-pressure-by-age) for the full category breakdown, and [when a reading is an emergency](/blood-pressure/high-blood-pressure-when-to-worry).

## How do I get an accurate reading?

Accuracy depends as much on technique as on the device: rest first, sit correctly, use the right cuff size, and take more than one reading. The full step-by-step is in our [how-to-measure guide](/blood-pressure/how-to-measure-at-home). Choosing the right device matters too — most clinicians recommend a validated [upper-arm monitor over a wrist model](/blood-pressure/upper-arm-vs-wrist).

## How a SonoHealth monitor fits

SonoHealth offers the **BPpro** and **BPMAX** upper-arm home blood pressure monitors, designed for simple, repeatable at-home readings. Used consistently and shared with your care team, a home monitor turns scattered numbers into a trend your doctor can act on. You can see both at [SonoHealth.com](https://sonohealth.com/shop/).

## When to involve your doctor

Home readings support — but never replace — professional care. Contact your doctor if your readings are consistently high, if you see an irregular-heartbeat flag, or if anything changes. And treat a reading at or above 180/120 with symptoms as a medical emergency: call 911.
