Blood Pressure Monitors

Blood Pressure Monitors

Blood pressure monitors are devices used to measure blood pressure, which is the force exerted by the blood against the walls of the arteries as it circulates through the body. Blood pressure monitors come in two primary varieties:

Manual Sphygmomanometers

  • Consist of an inflatable cuff, a measuring unit (mercury manometer or aneroid gauge), and a mechanism for inflation (manual bulb and valve or electric pump)
  • To momentarily stop blood flow, the cuff is inflated and wrapped around the upper arm.
  • Air is slowly released from the cuff while a stethoscope is used to listen to the artery, allowing the systolic (peak) and diastolic (lowest) pressures to be determined

Digital Blood Pressure Monitors

  • Use an inflatable cuff and electronic sensors to detect blood flow
  • The cuff automatically inflates and slowly releases air, while the monitor calculates the systolic and diastolic pressures
  • The readings appear on a computer screen.
  • Digital monitors are easier to use and more convenient for home monitoring compared to manual devices

Both manual and digital blood pressure monitors can be used on the upper arm or wrist. Home monitors should be validated, fit the user’s arm properly, and be used consistently for accurate results. Regular calibration is also important for maintaining accuracy over time.

What are the differences between manual and digital blood pressure monitors?

Digital blood pressure monitors differ from manual ones in several key ways:


  • Digital monitors automatically inflate and deflate the cuff, while manual monitors require manual inflation using a rubber bulb.
  • Digital monitors automatically calculate and display the systolic and diastolic blood pressure readings, eliminating the need for a stethoscope and manual observation.

Ease of Use

  • Digital monitors are generally easier to use, especially for home monitoring, as they provide quick and easy readings with minimal training required.
  • Manual monitors require more skill and practice to use effectively, often requiring assistance to obtain accurate readings.


  • When used correctly by trained professionals, manual monitors are considered more accurate than digital ones.
  • Digital monitors may struggle to detect irregular heart rhythms accurately and can be affected by factors like incorrect cuff placement or movement artifacts.
  • However, modern digital monitors are very accurate for most people, with inaccurate readings occurring in only 5-15% of cases.


  • Manual monitors are typically less expensive than digital monitors upfront.
  • Digital monitors often include additional features like memory functions for tracking readings over time.

In summary, while digital blood pressure monitors offer convenience and ease of use, manual monitors are preferred when the highest level of accuracy is required, such as in clinical settings. For most people, especially for home monitoring, digital monitors provide adequate accuracy and are a suitable choice.

Home Blood Pressure Monitors

Home blood pressure monitors come in two primary varieties:

  • Arm monitors
  • Wrist monitors

Arm monitors

A cuff that is wrapped around your upper arm is used by arm blood pressure monitors. There are two types of arm monitors:

  • Aneroid monitors: You inflate the cuff by squeezing a bulb, then read the pressure from a gauge.
  • Digital monitors: The monitor automatically inflates the cuff and displays your blood pressure reading on a digital screen.

Arm monitors generally provide more accurate readings compared to wrist monitors. Arm monitors are frequently preferred by doctors over wrist monitors.

Wrist monitors

Wrist blood pressure monitors use a cuff that wraps around your wrist. They are smaller and more portable than arm monitors, but the readings can be more sensitive to body position. Wrist monitors may be less accurate than arm monitors.

When choosing a home blood pressure monitor, it’s important to pick one that fits your arm or wrist properly and has features like irregular heartbeat detection and data averaging. Regularly calibrating your monitor is also recommended.

Best Home Blood Pressure Monitors

OMRON blood pressure monitors are highly recommended by doctors and pharmacists for providing accurate and reliable home blood pressure readings.

Key features to look for in a good home blood pressure monitor include:

  • Automatic wrist and finger monitors are less dependable than cuff-style monitors worn on the upper arm (biceps).
  • Validated for clinical accuracy, such as being on the U.S. Blood Pressure Validated Device Listing (VDL)
  • Ability to detect irregular heartbeats and provide risk category indicators
  • Multi-user memory and data averaging functions
  • Large display for easy reading

Home blood pressure monitoring is essential for managing hypertension, which affects nearly 50% of adults in the U.S.  It allows you to get an accurate, consistent picture of your heart health and see if treatments are working.

The American Heart Association recommends home monitoring for anyone diagnosed with high blood pressure, as well as those starting or changing treatment.  It’s important to use the monitor correctly by taking multiple readings at the same time each day and keeping a log to share with your doctor.

When choosing a home blood pressure monitor, make sure to get one that fits your arm size properly.  You should also have your doctor or pharmacist check that the monitor is giving accurate readings compared to their equipment.

Ambulatory Blood Pressure Monitors

Ambulatory blood pressure monitors are portable devices used to continuously measure a person’s blood pressure over a 24-hour period as they go about their daily activities. The key points are:

  • Ambulatory blood pressure monitoring provides frequent readings of blood pressure and heart rate over a 24-hour period, both when awake and asleep.
  • It helps diagnose and manage high blood pressure (hypertension) by detecting abnormal blood pressure patterns that may be missed with occasional office measurements.
  • The monitor consists of a blood pressure cuff attached to a lightweight recording device worn on the body. It automatically takes readings at regular intervals, usually every 15-30 minutes during the day and every 60 minutes at night.
  • Ambulatory monitoring can detect white coat hypertension, masked hypertension, and nocturnal hypertension – conditions that may not be evident from occasional office readings.
  • Healthcare providers use ambulatory monitoring to get a more accurate picture of a person’s blood pressure and guide treatment decisions.

In summary, ambulatory blood pressure monitors provide comprehensive, continuous blood pressure data over a 24-hour period to help diagnose and manage hypertension more effectively than occasional office measurements.


1: What is bp log sheet?

A blood pressure (BP) log sheet is a tool used to record and track your blood pressure readings over time. The key features of a BP log sheet are:

  • Columns to record the date, time of day (AM/PM), systolic and diastolic blood pressure readings, and pulse rate.
  • Instructions on how to properly measure blood pressure, such as sitting comfortably with feet on the floor and resting your arm at heart level.
  • A place to note your target or goal blood pressure range.
  • Space to write any comments or notes about the readings.
