Technology and Blood Pressure Monitoring
Blood pressure monitoring is a scientific process whereby measurements of pressure of blood are taken and analyzed to identify any changes in the blood pressure over a period of time. Blood pressure monitors are available in two forms, fixed and removable.
The fixed monitors usually have a cuff that is worn on the arm and measures the pressure of the blood against the wall of a blood vessel. Most of the measured pressure result from the heart pumping blood throughout the body.
When using the term “fixed blood pressure meter” without qualification, the word “fixed” refers to the internal mechanism of the machine. A removable cuff that is placed around the arm is attached to a monitoring device that has a monitor dial.
This dial can be turned by the user to measure the patient’s blood pressure. The air pressure cuff used for this method is similar to the one used in a bathroom for taking the pressure of a water bath. The user places his or her arm in the water bath while the dial is turned to measure the blood’s pressure.
If you plan to use a blood pressure device to monitor your blood pressure, either of the two methods described above will be fine. In order to choose the best product, it is important that you consider factors such as accuracy, reliability and durability of the product.
Buying an expensive digital blood pressure monitor with automatic adjustment features may not prove to be very accurate and may also lead to discomfort for the user. You may opt to buy a unit with only a digital dial and no mechanical parts.
Technology and blood pressure are always associated with each other
They are very closely related. They have often gone hand in hand since the beginning of reliable recording technology. Early methods of monitoring hypertension involved the use of pricking patients with needles and later measuring the pressure of the blood using the antique hygienic known as the blood pressure corsage.
This method was not successful in determining high blood pressure but was very effective in determining hypertension or low blood pressure. In the early part of the twentieth century, digital monitoring and automatic pricking were developed.
Today, these devices are called digital monitors and are used widely by health professionals all over the world. They are now used primarily for recording patient’s readings. Although some patients may still prefer the use of a cuff around their arm or waist for monitoring blood pressure, more sophisticated devices are now available.
These devices can be used for more intricate measurements such as recording of arterial and venous displacement. The cuff is a closed system that is inflated and deflated on the spot. Two types of the cuff are available: the first one is called the monitor cuff, and the second one is called the field cuff.
The monitor cuff is the traditional measurement device and can measure up to nine pounds of pressure. The field cuff can measure up to forty pounds of pressure. Both of these measurements are still considerably better than the conventional measurements.
This cuff measures blood pressure, while a probe is attached to the skin directly above the bladder. The pressure of blood flow can then be measured and displayed on a computer screen. This makes it possible to display different types of clinical presentations, including blood pressure elevations in a patient’s arm.
There are also new non-invasive devices now available
These devices, such as Omron’s Oxygen Spectrometer, are capable of measuring blood pressure in the absence of an actual physical exam. They do not require anaesthetics and are therefore ideal for routine monitoring. Non-invasive devices allow for rapid measurements.
In fact, many physicians today recommend these devices for routine monitoring. A non-invasive option is the wrist monitor. These devices are often worn by health professionals who have a need for accurate and continuous measurements.
An observer places a thin, clip-like probe at the base of the wrist and measures blood pressure as it is transmitted by the skin. For many people, wearing a wrist monitor has never been so comfortable! Technology has also made it easier to make reliable measurements in the home.
A blood pressure monitor is now available that can accurately measure blood pressure
- In the arm
- The legs
- The abdomen
- The face
In the past, most monitors relied on the ability of a patient’s arm to flex during movement, making the measurement less accurate. Today, reliable measurements can be obtained even when the arm is immobile, as the arm length and the diameter of the measurement device itself have increased.
Technology has improved the ability to interpret measurements. Previously, when measurements were performed on patients with hypertension, the interpreters had to use manual equipment to interpret the measurements.
With the new equipment, the interpretation of measurements has been made easy. Today, individuals with hypertension can receive accurate readings from their own home. One of the most important measurements that the patient receives from their doctor or nurse is the systolic blood pressure measurement.
This measurement, which represents the amount of blood pumped out of the heart, tells the patient the pressure of their heart as well as the stress involved in their heart’s operation. While accuracy was not always optimal, today’s devices can provide an accurate systolic measurement of only about 10 mm Hg.
This high level of accuracy is great for people who need to be consistently monitored and for people who need their blood pressure to be closely monitored in order to prevent any potential health complications.
The importance of an accurate stethoscope cannot be underestimated
Often, patients undergo different types of medical procedures at one time or at several different times. For this reason, it is important that a reliable stethoscope is used in order to receive the best possible blood pressure reading.
Today’s automated devices for measuring pressure provide this capability. Rather than the need to constantly re-measure pressure and replace a worn-out stethoscope, today’s automated devices can allow for a continuous, long-lasting measurement between readings.
Another common form of monitoring that is often applied in medical settings is called “daytime ambulatory blood pressure.” Typically, this equipment is utilized by emergency medical technicians and paramedics in order to provide immediate monitoring for patients that are experiencing hypertension.
Traditionally, the monitor used for this application contained a single, handheld pressure transducer. Modern pressure measuring devices incorporate a number of different types of transmitter and receivers, each contributing to a better ability to measure blood pressure.
In addition, some of these newer systems include the use of an observer that can provide colour commentary on the data being measured. These monitors and receivers are typically more compact, easier to use, and more accurate than their predecessors.
