Blood Pressure Check Up

Blood Pressure Check Up

Blood pressure is the force with which your blood pushes against the walls of your arteries as it is pumped around your body. A blood pressure check up is the only way to find out what your blood pressure is, and it could save your life.

Blood pressure is measured in millimeters of mercury (mmHg) and is given as two numbers – the systolic pressure (when your heart pushes blood out) and the diastolic pressure (when your heart rests between beats). A blood pressure reading between 90/60 mmHg and 120/80 mmHg is regarded as normal.
Every five years, as part of the NHS Health Check, if you’re over forty, you should have your blood pressure checked. You can get your blood pressure tested at your local pharmacy, GP surgery, or some workplaces. Home blood pressure monitoring is also recommended, especially if you have been diagnosed with high or low blood pressure.

To check your blood pressure at home, you’ll need an automatic, cuff-style, upper arm monitor that has been validated. Follow the instructions carefully, avoid factors that can temporarily raise blood pressure, and record your readings. Bring your home monitor to your doctor’s office annually to check its accuracy.

If your blood pressure reading is high (135/85mmHg or higher at home, or 140/90mmHg or higher at a clinic), you may be at risk of developing serious health problems like heart attacks and strokes. Your doctor can provide advice and treatment to help control your blood pressure.

Methods to Check Blood Pressure

Monitoring your blood pressure is an important part of maintaining good health. Here are some common methods to check your blood pressure:

Home Blood Pressure Monitoring

  • Invest in an at-home blood pressure monitor. These devices are widely available and easy to use.
  • To guarantee accurate readings, carefully follow the instructions.
  • Measurements should be taken at regular times of day, such as in the morning and evening.
  • Take note of your readings and monitor any variations over time.

Clinic or Doctor’s Office Measurement

  • When visiting your healthcare provider, they will use a professional-grade blood pressure cuff and monitor to take your reading.
  • The healthcare provider will place the cuff around your arm and inflate it to measure the pressure in your blood vessels.
  • They will record your systolic (top number) and diastolic (bottom number) blood pressure readings.

Ambulatory Blood Pressure Monitoring

  • This method involves wearing a portable blood pressure monitor for 24 hours or more.
  • The device automatically takes readings at regular intervals, providing a comprehensive picture of your blood pressure throughout the day and night.
  • This can be helpful in detecting any fluctuations or patterns in your blood pressure.

Wearable Devices

  • Some smart watches and fitness trackers now include built-in blood pressure monitoring capabilities.
  • These devices use sensors to measure your blood pressure and provide real-time readings.

While convenient, it’s important to cross-reference the readings with a traditional blood pressure monitor for accuracy.

Regardless of the method you choose, it’s important to follow the instructions carefully and consult with your healthcare provider to ensure you are obtaining accurate and reliable blood pressure readings. Regular monitoring can help you and your doctor identify any potential issues and take appropriate action to maintain your cardiovascular health.

How to check Blood Pressure?

To check blood pressure manually:

  • Locate the brachial artery by palpating the inside of the elbow crease.
  • Wrap the blood pressure cuff around the upper arm, with the artery arrow pointing to the brachial artery.
  • Inflate the cuff until you can no longer feel the brachial pulse, which gives an estimate of the systolic pressure.
  • Slowly release the air from the cuff and listen with a stethoscope for the first Korotkoff sound, which is the systolic pressure.
  • Continue to slowly release the air until the last Korotkoff sound is heard, which is the diastolic pressure.

To check blood pressure automatically:

  • Encircle the upper arm with the cuff.
  • On the monitor, press the power button.
  • Systolic and diastolic readings will be shown on the monitor as the cuff automatically inflates and deflates.

The cuff will automatically inflate and deflate, and the monitor will display the systolic and diastolic readings.

The automatic method is simpler and recommended by the American Heart Association for home blood pressure monitoring.

Blood Pressure Tests

Blood pressure tests measure the pressure in the arteries as the heart pumps blood through the body. They are used to diagnose high blood pressure (hypertension) and low blood pressure (hypotension).

Key points about blood pressure tests:

  • They are a routine part of most health checkups and are an important screening for high blood pressure, which increases the risk of heart attacks and strokes.
  • The test involves wrapping a cuff around the upper arm that inflates and measures the pressure as it deflates. The systolic pressure (when the heart pumps) and diastolic pressure (when the heart rests) are recorded.
  • Normal blood pressure is considered between 90/60 mmHg and 120/80 mmHg. High blood pressure is 135/85 mmHg or higher at home, or 140/90 mmHg or higher at a clinic. Low blood pressure is 89/59 mmHg or lower.
  • Additional tests like blood and urine tests may be done to check for causes of high blood pressure and organ damage if hypertension is diagnosed.
  • Home blood pressure monitoring with an automated cuff can be used to check blood pressure regularly. Ambulatory monitoring over 24 hours may also be done in some cases.

In summary, blood pressure tests are a quick, painless way to check for high or low blood pressure and monitor heart health. They are an essential part of routine health screenings.


1: What is bp log sheet?

A blood pressure log sheet is a simple tool to record your blood pressure readings over time. It typically includes columns for the date, time of day (AM/PM), systolic blood pressure, diastolic blood pressure, and pulse rate. Some logs also have a comments section to note any relevant factors like stress, exercise, or medications.

The key instructions for using a blood pressure log are:

  • Measure your blood pressure twice daily, morning and evening, at consistent times
  • Sit comfortably with your feet flat and arm supported at heart level when taking readings
  • Record the systolic (top number) and diastolic (bottom number) blood pressure values
  • Take note of your blood pressure and pulse rate.
  • Bring the completed log to share with your doctor at appointments

Using a blood pressure log allows you to track your readings over time and spot any patterns or changes. This helps you and your doctor monitor your blood pressure and make treatment decisions if needed. The American Heart Association and other health organizations provide free printable blood pressure log templates.

2: Can apple watch measure bp?

The Apple Watch cannot directly measure blood pressure on its own. To measure blood pressure using an Apple Watch, you will need to pair it with a compatible blood pressure monitoring device that connects to the Apple Watch via Bluetooth.

Some examples of Apple Watch-compatible blood pressure monitors include:

  • A wireless arm blood pressure monitor, the iHealth Feel
  • Omron Evolv Wireless Blood Pressure Monitor
  • QardioArm Wireless Blood Pressure Monitor

These connected devices allow you to take blood pressure readings on your Apple Watch by syncing the data from the blood pressure cuff to the Apple Watch’s Health app.

However, the Apple Watch itself does not have the ability to directly measure blood pressure without an additional accessory device. Using a conventional upper arm blood pressure cuff is the only method of measuring blood pressure that is medically accurate.

So in summary, while you cannot directly measure blood pressure with the Apple Watch alone, you can use it in conjunction with a compatible wireless blood pressure monitor to track your readings conveniently on your wrist.

3: How reliable are cuffless blood pressure measurement technologies?

The reliability and accuracy of cuffless blood pressure measurement technologies is still a significant challenge:

  • The current standards for validating automated blood pressure devices, such as the AAMI/ESH/ISO criteria, are not appropriate for evaluating cuffless devices. Cuffless devices have unique validation issues that need to be addressed.
  • Many studies on the accuracy of cuffless BP devices have used inadequate methodology and have potentially misleading conclusions. More rigorous validation protocols are needed to properly assess the performance of these devices.
  • Cuffless devices that use surrogate signals like photoplethysmography (PPG) to estimate blood pressure, without directly measuring pressure, face significant challenges in providing reliable and well-calibrated BP readings. The relationship between these surrogate signals and actual BP can be variable and unstable.
  • Factors like age, hypertension status, and changes in vascular properties can affect the accuracy of cuffless BP measurements, even if the devices perform well under static, controlled conditions.
  • The European Society of Hypertension does not currently recommend the use of cuffless BP devices for clinical diagnosis and management of hypertension due to the lack of validated performance.

In summary, while cuffless BP monitoring technologies are promising, they have not yet demonstrated the level of reliability and accuracy required to replace traditional cuff-based blood pressure measurement for clinical purposes. More research and development is needed to address the unique validation challenges of these devices before they can be widely adopted.
