  • Blood Pressure Monitor

    A sphygmomanometer is a medical device used to measure blood pressure. It consists of several components, including an inflatable cuff, a pressure gauge (either mercury or aneroid), and a mechanism to control the release of pressure.

    Here's a breakdown of the different parts:

    1. Inflatable Cuff: The cuff is made of a flexible and inflatable material, typically wrapped around the upper arm. It is designed to occlude the brachial artery when inflated.

    2. Pressure Gauge: The pressure gauge is used to measure the pressure within the cuff. There are two common types of pressure gauges used in sphygmomanometers:

      a. Mercury Manometer: This type of gauge uses a column of mercury to indicate the pressure. As pressure is applied to the cuff, the mercury rises in a vertical tube, providing a numerical reading.

      b. Aneroid Manometer: Instead of mercury, an aneroid gauge uses a small, flexible metal or alloy chamber. This chamber expands or contracts with the changing pressure, and the movement is mechanically amplified to display the pressure on a dial.

    3. Control Valve: The sphygmomanometer also includes a control valve or a bulb to inflate and deflate the cuff. When inflated, the cuff compresses the brachial artery, temporarily stopping the blood flow.

    The procedure for measuring blood pressure using a sphygmomanometer typically involves the following steps:

    1. The cuff is wrapped securely around the upper arm, with the bottom edge aligned above the elbow.

    2. The cuff is inflated by squeezing the bulb or activating an automated inflation mechanism. This inflation causes the cuff to press against the brachial artery, temporarily cutting off the blood flow.

    3. Once inflated, the pressure in the cuff is gradually released using the control valve. As the pressure decreases, blood flow resumes, and the healthcare provider listens to the sounds of blood flow using a stethoscope placed over the brachial artery.

    4. The healthcare provider monitors the pressure gauge and listens for the sounds of Korotkoff (audible changes in blood flow) to determine the systolic and diastolic blood pressure readings.

    It's worth noting that while mercury-based sphygmomanometers were commonly used in the past, they are gradually being phased out due to environmental concerns associated with mercury. Aneroid sphygmomanometers and digital blood pressure monitors are now more prevalent, offering accurate and convenient alternatives.

  • What is a Blood Pressure Monitor

    There are indeed different types of blood pressure monitors available, each with its own features and functionalities. Here are the three main types you mentioned:

    1. Manual or Aneroid Blood Pressure Monitors: These monitors consist of an inflatable cuff that is wrapped around the upper arm and a stethoscope. The cuff is manually inflated by squeezing a rubber bulb, and then slowly released while listening with the stethoscope for the sounds of blood flow. This method requires some skill and practice to accurately measure blood pressure, as it relies on the observer's ability to hear and interpret the sounds (Korotkoff sounds) produced as blood flows through the arteries.

    2. Semi-Automatic or Digital Blood Pressure Monitors: These monitors also involve an inflatable cuff that is wrapped around the upper arm, but they have an automated pump to inflate the cuff. Instead of using a stethoscope, a digital display is used to show the blood pressure readings. The user manually operates the inflation of the cuff using a built-in pump, and the monitor automatically deflates the cuff while measuring and displaying the blood pressure readings.

    3. Fully Automatic or Digital Blood Pressure Monitors: These monitors are the most common type found in homes and clinics. They are fully automated and user-friendly. The cuff is placed on the upper arm, and with a press of a button, the machine automatically inflates the cuff, measures the blood pressure, and displays the readings on a digital screen. These monitors often have additional features like memory storage, irregular heartbeat detection, and averaging of multiple readings.

    It's important to note that regardless of the type of blood pressure monitor you choose, it's essential to follow the instructions provided by the manufacturer and ensure proper cuff placement for accurate readings. Additionally, periodic calibration and verification against professional measurements are recommended to maintain accuracy.


    Basically, the units are all similar. They have a blood pressure cuff that goes around the arm, goes above the elbow. There’s on/off buttons to turn the machine on and do the reading.   Often seeing a local family physician or a physiotherapist in conjunction with a registered dietitian and athletic therapist is a great option to take control of this condition. Smart Food Now and exercise is also optominal for overall health.

    There are wrist blood pressure monitors available that can be worn around the wrist to measure blood pressure. However, it's worth noting that wrist blood pressure monitors may not always be as accurate as the traditional upper arm blood pressure monitors.

    When using a blood pressure monitor, regardless of the type, it is indeed crucial to place the cuff appropriately for accurate readings. The cuff should be positioned on the bare skin of the upper arm, just above the elbow, and it should fit snugly but comfortably. It's recommended to remove any tight clothing or accessories that may interfere with the accuracy of the measurement.

    For the most reliable results, it's generally advised to use upper arm blood pressure monitors, especially those validated by reputable medical organizations. These devices tend to provide more consistent and accurate readings compared to wrist monitors. If accuracy is a concern, consulting with a healthcare professional about the best type of blood pressure monitor for your specific needs would be advisable.

    Blood pressure changes and fluxes throughout the day, so when you do your blood pressure checking at home, you want to sort of keep things equal as best you can. So if you’re checking your blood pressure once a day, try to check it around the same time, with the same variables in play.

    For example, you might want to check blood pressure first thing in the morning when you wake up. That tends to be at the lowest. There’s less stress factors, as well, so it might be the lowest reading.

    When you do your blood pressure readings, what you really want to do ideally is to check it three times in a row. But we want you to wait two to three minutes between each reading. That allows the arteries to rebound, and it just allows for a more accurate reading. So if you do three readings, two to three minutes between, that would be ideal, and then average those readings.

    When you see the doctor in the doctor’s office, and the doctor does the blood pressure, that’s just really representive of only one time of the day, that blood pressure, whereas if you’re doing monitoring at home, you’re getting a large number of readings throughout the day.

    Many of these blood pressure units will have memories on them, and they will stamp the memory with the date and the time. And you can show your physician that. If not, you can also just do a nice log of the readings.

    Making any change in your medication for blood pressure should be done with you and your doctor. And all your blood pressure readings that you get at home should be taken into your physician. It gives the physician a great idea and understanding of what your blood pressure is through the day, through the weeks, through the months. And the doctor can do the assessment.
