Blood Pressure (BP) is simply the pressure produced by the heart pumping blood into our arteries.  No great mystery here!  However, what may not be obvious to many is that BP fluctuates throughout the day in response to our physical and mental activities.  Therefore, BP measurement rules have been established by the medical community to minimize this variability and increase usability of results.  The basic rule is simply to reach a state of rest before a BP measurement.

Why is this so important to understand?  Because “Resting BP Results” are used to effectively Classify, Diagnose and Treat High BP or Hypertension (see table).  Additionally, using resting results establishes a credible BP baseline from which both you and your MD can easily compare different treatments to find what works best for you.  Treatments can be Life Style Changes (diet, exercise, etc.) to Medications prescribed by your MD.  Non-Resting BP measurements can produce results that are erratic and difficult to understand, making classification and treatment comparisons difficult and possibly invalid.

Only two BP parameters are used to classify BP: Systolic Pressure (SP) and Diastolic Pressure (DP).  During a single heart beat, SP is the highest pressure and DP is the lowest pressure; usually displayed as SP/DP or, as an example, 145/89.  A blood pressure monitor senses these high (SP) and low (DP) results and displays along with Pulse Rate.

The Blood Pressure Classification displayed below was changed in 2017.  Click Normal BP Range in the Navigation Frame to view the New Classification.

OK, now let’s take a look at how BP is actually classified.  Home BP is classified from the average of five or more BP results measured on five or more days using Resting BP Procedures.  Yes, I know, “Resting BP” has now changed into a "Procedure", but results will be properly classified, more usable, and help your MD find the best treatments to lower your blood pressure.

Resting BP Procedures differ for Upper Arm and Wrist Monitors and can be viewed in your monitor manual or at  Below is a combined procedure for Upper Arm & Wrist monitors so you can see for yourself just how easy it really is:

  • DO NOT smoke, take recreational drugs, exercise, eat or drink (alcoholic or caffeinated) beverages 30 minutes before a BP measurement.
  • Place the BP cuff on your bared upper left arm or wrist.
  • Make sure the cuff is snug (not too tight) and fits comfortably.
  • Sit quietly and relax for 5 minutes with your left arm and back supported and both feet on the floor. DO NOT cross your legs.
  • After resting for 5 minutes, measure your Resting BP according to instructions in your Monitor User Manual or as directed by your MD.

Now, I know what you are thinking, “Why doesn’t my MD  use this procedure?”   The simple answer is that they try, but many patients can not actually reach a state of rest in a doctor’s office.  Therefore, BP measured in a medical environment, where anxiety may be elevated, is usually considered a screening test for hypertension.  The American Society of Hypertension recommends that both MD Office and Home BP results be used to Classify, Diagnose, Treat and Manage BP.

Creditable Home BP measurements, along with MD Office results, are now being used to better diagnose and treat hypertension.  Personal BP monitor technology has greatly improved, but it’s up to you to measure your BP properly using Resting BP Procedures.   Most BP monitors display accurate results, but accurate “non-resting” results are basically … unusable.
