Diagram of Sphygmomanometer

The diagram of sphygmomanometer helps us understand the various parts of the device. A sphygmomanometer is used to measure blood pressure. It enables healthcare professionals to detect various conditions accurately and on time. In this article, we are going to learn about the diagram of sphygmomanometer, along with its various parts and the different types of sphygmomanometer.

What is Sphygmomanometer?

The sphygmomanometer is used to measure blood pressure. A sphygmomanometer is also called a BP machine, blood pressure monitor, or blood pressure cuff. The sphygmomanometer was invented by an Austrian physician, Samuel Karl Ritter Von Basch in 1881. It consisted of a mercury manometer attached to another infected cuff and a pressure bulb.

Parts of Sphygmomanometer

A sphygmomanometer parts diagram is given above. The various parts of sphygmomanometer are:

Parts	Description
Cuff	A fabric sleeve wrapped around the arm to apply pressure.
Manometer	Display blood pressure readings in mmHg.
Bulb	Handheld pump used to inflate the cuff.
Valve	To control inflation of the cuff
Tubing	Flexible tubing connecting the cuff to the manometer.

Types of Sphygmomanometer

There are majorly 3 types of sphygmomanometer used in clinical settings :

Mercury Sphygmomanometer

It is the traditional sphygmomanometer which consists of a Mercury-filled manometer attached to an inflatable cuff and a pressure bulb. Although it shows more accurate readings than all other sphygmomanometers, the only drawback of this sphygmomanometer is Mercury exposure.

Android Sphygmomanometer

It consists of a mechanical gauge with a pointer that moves along a scale to indicate blood pressure readings. This sphygmomanometer is easy to use ,carry and no Mercury exposure is there which was the problem in Mercury sphygmomanometer. One drawback in sphygmomanometer is that they require periodic calibration to maintain accuracy.

Digital Sphygmomanometer

Digital sphygmomanometer is the modern and most recently invented sphygmomanometer. It is widely used not only by health professionals but also by common people. It is easy to use and anyone can use it at home. It has so many advanced features which were not there in the previous two sphygmomanometers. Digital sphygmomanometer uses electronic sensors and a digital display to measure and display reading; it also provides features like irregular heart beat detection, automatic inflation and memory storage.

How to Use a Sphygmomanometer?

The procedure of using a sphygmomanometer is as follows:

• First ask the patient to be in a relaxed state, wrap the cuff around the arm of the patient just three fingers above the antecubital fossa. Make sure that the cuff is not too tight and not too loose there should be enough space between arm and cuff to insert one or two fingers
• Inflate the rubber bulb and put a diaphragm of stethoscope on the brachial artery (antecubital fossa) , inflate it till 180 mmHg .
• Start deflating it by adjusting the valve until you hear a beating sound . The point where sound comes is called systolic pressure. Normal systolic pressure should be 120 mmHg. Systolic pressure more than 130 mmHg is high blood pressure.
• Note the systolic pressure and continue deflating the cuff again by adjusting the valve till the beating sound disappears ,this is the diastolic pressure. Normal diastolic pressure should be 80 mmHg. Diastolic pressure more than 90 mmHg is called hypertension.

Conclusion – Diagram of Sphygmomanometer

Nowadays medical machines have transformed the overall health care, especially In India. These changes are not in only one aspect but in all aspects such as monitoring, accuracy of diagnosis, Minimally Invasive Procedures , easy accessibility ability. Despite improvement in technology, mercury sphygmomanometers are being phased out due to environmental concerns. Android and digital sphygmomanometer are more user-friendly, portable and can be used at home . Therefore they are more commonly used than mercury sphygmomanometers.

FAQs on Diagram of Sphygmomanometer

What are the Main Parts of Sphygmomanometer?

The Sphygmomanometer mainly consists of: Manometer, cuff, tubeing, bulb and a valve.

How many Types of Sphygmomanometer are There?

There are broadly three types of sphygmomanometer namely: mercury sphygmomanometer, android sphygmomanometer and digital sphygmomanometer. 

What is Sphygmomanometer with Diagram?

Sphygmomanometer is a machine which can mesure blood pressure. The labeled diagram of Sphygmomanometer is given at the top of the article.

What is Sphygmomanometer Class 7?

A sphygmomanometer is a medical device used to measure blood pressure by wrapping a cuff around the arm and inflating it to restrict blood flow, then slowly releasing the pressure while listening for specific sounds through a stethoscope.

What is the Principle and Working of Sphygmomanometer?

A sphygmomanometer measures blood pressure by using a cuff inflated with air, then gradually releasing pressure while listening for sounds with a stethoscope, which gives systolic and diastolic pressure.
