A close-up of BP monitor

For SMBP measurement interpretation, an average systolic BP and average diastolic BP of 135/85 mm Hg is considered equivalent to 140/90 mm Hg in the clinical setting. If the BP used to diagnose hypertension and as a treatment target in the clinical setting is 140/90 mm Hg, the corresponding SMBP diagnostic threshold and treatment target is 135/85 mm Hg.

SMBP quick guide

AMA's self-measured blood pressure quick guide offers an easy reference for physicians and care teams to help train patients to perform SMBP monitoring.

In the 2017 American College of Cardiology/American Heart Association "Guideline for the Prevention, Detection, Evaluation, and Management of High Blood Pressure in Adults," 130/80 mm Hg is used as the diagnostic threshold for hypertension.1 When following the recommendations in this guideline, 130/80 mm Hg can be used for most patients as the treatment target for hypertension in clinical settings and for SMBP. The ultimate judgment regarding treatment targets and management plans must be made by physicians and patients based on individual patient factors.

The measurement ranges and interpretations presented in the tables are based on the 2003 "Seventh report of the joint national committee on prevention, detection, evaluation, and treatment of high blood pressure" (JNC-7) diagnostic and treatment target thresholds.2 If the 2017 ACC/AHA Hypertension Clinical Practice Guideline is used, hypertension is defined as BP > 130/80 mm Hg for both office-based measurements and SMBP, and controlled BP for most adults is defined as < 130/80 mm Hg.

For both tables, if systolic and diastolic BPs are in different categories, defer to the higher category of BP.

The guide (PDF) highlights seven key steps physicians and care teams can take to use SMBP with patients 18 years and older with high blood pressure, and includes links to useful supporting resources.
