Having good blood pressure helps to maintain good immunity and reduces the risk of a heart attack by 25% in humans. Measuring blood pressure regularly using a blood pressure machine prevents you from visiting the doctor. 

Blood pressure machines are medical devices or sphygmomanometers that are used to measure blood pressure. In the Indian market, there are two types of BP machines: digital BP machines and manual BP machines. 

While both devices are used to measure blood pressure, people often get confused about which is more accurate between manual BP and digital BP monitors. 

Digital Blood Pressure Machine:

Digital BP machines are often known as automatic blood pressure machines. These are advanced medical devices that have gained immense popularity in recent years because of their accuracy and convenience. These sphygmomanometers, like the Romsons BPX Plus fully automatic BP machine, are easy to use, portable, and give precise readings. This makes it a common choice for both healthcare experts and individuals monitoring their blood pressure at home.  

A digital blood pressure machine consists of several key components:

Cuff: The cuff is wrapped around the upper arm and is responsible for inflating and deflating to measure blood pressure.

Display Unit: This unit typically includes an LCD screen that displays the blood pressure readings, pulse rate, and sometimes additional information such as irregular heartbeat detection.

Inflation Mechanism: These machines use an automatic inflation mechanism to inflate the cuff to the appropriate pressure level for measurement.

Microprocessor: A built-in microprocessor controls the inflation, deflation, and calculation of blood pressure readings.

Manual Blood Pressure Machine:

Manual BP machines are often referred to as mercury sphygmomanometers. These machines use traditional methods to measure the pressure in the human body. Before the popularity of digital blood pressure monitors, mercury BP machines were considered the ‘Gold Standard’ to measure blood pressure readings in India. Manual sphygmomanometers need human intervention for both inflation and measurement. 

A manual blood pressure machine embodies several key components:

Cuff: Similar to digital machines, manual devices also use a cuff, which is wrapped around the upper arm.

Stethoscope: In manual blood pressure measurements, a stethoscope is used to listen to the Korotkoff sounds, which indicate blood flow in the arteries.

Pressure Bulb: The pressure bulb is used to manually inflate the cuff by squeezing it. The person taking the measurement has control over the rate of inflation.

Manometer: This is a gauge that displays the pressure reading in millimeters of mercury (mmHg). It consists of a dial or column of mercury.

Which is Better? Digital or Manual BP Machine

While some doctors still use manual BP machines, digital blood pressure machines are better in every factor, whether it’s convenience, precision, portability, or pricing. 

If you are also looking to buy a digital BP machine, try the Romsons BPX Plus fully automatic digital blood pressure machine, which comes with a large LCD display, stores up to 120 readings in memory and comes with one year of warranty.

  1. I’ve been exploring for a little bit for any high-quality articles or blog posts in this kind of house
    . Exploring in Yahoo I eventually stumbled upon this site.
    Reading this information So i am happy to convey that I’ve a very good uncanny feeling I discovered exactly what I needed.
    I most for sure will make certain to don?t put out of your mind this site and give it a glance on a relentless basis.
