Mercury and Digital pressure Monitor

The sphygmomanometer in all its forms contains a cuff that is attached around the person’s arm. There are many types of it; one is a mercury sphygmomanometer, and another called a digital or digital sphygmomanometer, There are many types of it; one is mercury sphygmomanometer, the mercury sphygmomanometer is the most accurate pressure measuring device and thus the diagnosis is accurate, It does not need to be calibrated more than once to get accurate results.

The movement of the mercury pressure gauge affects the accuracy, so it must be placed in a flat place to maintain the place of mercury inside it. This device also causes some risks because it contains dangerous mercury. For the possibility of breaking the device and leakage of material from it.

A digital blood pressure machine; is a modern device that works by using electronic batteries and a microphone to measure the force of blood pumping through the arteries. It is a practical and easy-to-use device. All he needs To measure the pressure, put the cuff around the patient’s arm, and read the numbers on the screen. You can control it by pressing the buttons, and the cuff automatically shrinks after completing the measurement, which is more expensive than the mercury device.

 

Disadvantages of the mercury pressure Device?

Mercury pressure gauges are cheaper and more accurate. However, there are some disadvantages:

The mercury pressure gauge contains mercury, which is toxic and dangerous to human life. So this device needs to always be careful to avoid breakage and mercury spillage, And if this happens; The fluid must be thoroughly cleaned. Which can get a little expensive.

Obtaining the result from the mercury pressure device requires the correct reading of the column of mercury. While other devices require less effort to get a reading.

The mercury pressure device requires very careful maintenance. To consistently show required and accurate results, For example, the mercury tube must be completely vertical wherever it is placed. In the event of any deviation, this will affect its accuracy.

The mercury compressor needs to replace the filter or its vent frequently, which allows outside air to be drawn in, If this is ignored, the response of mercury will be delayed inside the column. Thus obtaining inaccurate readings.

The mercury inside the mercury pressure cooker is sometimes subjected to oxidation. which shows the mercury column is dirty, Thus the real mercury level is difficult to read.

 

Digital Pressure Monitor

A digital pressure Monitor The device can be calibrated by first sitting on a chair and relaxing for no less than 5 minutes with the back straight.

Then place the cuff of the blood pressure monitor around your upper arm, horizontally with the level of your heart.

press the device’s power button after that, Wait some time after the cuff begins to inflate and start the measurement.

The cuff will deflate after the measurement is completed, and you will notice that its inflation has deflated by 2 to 5 mm Hg. This drop is an indication that the blood pressure monitor is accurate and well-calibrated. Then the final reading will appear on the screen when the process is over. The standard reading for diastolic pressure should not be higher than 80. And it should be less than 120 for systolic pressure.
