Blood pressure measuring equipments assist you to measure the fluctuations in your blood pressure levels. This helps you to keep track of your BP readings that are determined to find the reasons behind it. You can also make use of the online data on equipments to measure blood pressure which is available in plenty.

Generally, doctors suggest BP patients to obtain a precise data of their BP levels by using blood pressure measuring equipments. It is possible to check your BP by visiting a physician or you can do it at your home as well. Conduct a good research about the various BP monitoring devices, so that you can select the appropriate device as per your needs.

Blood Pressure Measuring Equipments

To measure blood pressure, you need to evaluate the arterial pressure. For this, you require a device called 'sphygmomanometer', which is commonly used by doctors around the world. This device gives you the BP values that are usually measured in mercuric millimeters i.e. mmHg. Apart from this, there are various other types of BP monitoring equipments that are easily accessible in the market.

What are the Different Types of BP monitoring devices?

The different types of BP monitoring devices are as under:

• Aneroid BP Monitoring Device - This device has a gauge which is usually read when you look at a pointer placed on the dial. Here, you have to place the cuff around a person�s upper arm and has to be inflated by hand and by pressing a rubber bulb.
• Automatic Non-Invasive BP Measurement - This measurement requires electric supply wherein, only a single cuff is wrapped around the patient�s arm. A machine blows the cuff and when it is slowly deflated, a sensor measures the tiny oscillations in the cuff�s pressure caused by pulse rate. You get the systolic reading when the pulsations start, mean pressure when the pulsations are maximum and diastolic reading when the pulsations disappear finally.
• Digital Monitors - These have manual or automatic cuffs wherein the BP reading gets flashed on a small screen.
• Electronic Devices� Here, mercury is not used
• Oscillotonometer - This device allows measuring of both systolic and diastolic pressure without a stethoscope. It contains a bleed valve, a control lever, one large dial to read the pressures and two overlapping cuffs. When you inflate and wrap the cuff around your arm, adjust the bleed valve and gradually pull the force. Soon after you pull the control lever towards you; the needle jumps a little with the pulse. When the cuff pressure moves towards the systolic pressure, the needle moves speedily. You must release the lever to get the systolic pressure and pull the lever forward all over again, so that when the pressure is reduced, the needle jumps again swiftly. When you loosen the lever at maximum needle oscillations, the dial gives you the mean arterial pressure and when it is released, the dial gives you the diastolic pressure.
• Invasive Arterial Pressure Measurement - Invasive arterial pressure measurement helps you to constantly monitor your BP readings by every beat wherein a graph of pressure against time is displayed. Here, arterial pressure is directly measured by placing a cannula in an artery. For this, you need to connect the cannula to a sterile, fluid-filled system, which is attached to an electronic monitor.
