Medical practitioners utilise the sphygmomanometer to evaluate blood pressure through its device functions. The instrument consists of an arm cuff together with a pneumatic pump system which controls air pressure, and a display instrument. The evaluation of heart performance relies on the sphygmomanometer by both nurses and doctors.
Extreme blood pressure either high or low can indicate major medical issues. Using a sphygmomanometer is therefore quite crucial. It aids in early identification of abnormalities before they become more significant like strokes or heart attacks.
Hospitals, doctors’ offices, even homes utilise sphygmomanometers. They enable doctors to choose the optimal treatment for every patient by providing fast findings.
What Is a Sphygmomanometer?
The sphygmomanometer functions as a medical instrument that evaluates blood pressure through its three key components including a pressure gauge, an inflatable bladder cuff, and a built in stethoscope. The tool includes pressure measurement devices and an adjustable bladder cuff along with a stethoscope for listening to the Korotkoff sounds. The different heart cycle phases allow users to distinguish between systolic and diastolic readings through the detected sounds. Arterial palpation of the brachial artery helps to correctly position the cuff on the upper arm. Every hospital and clinic operating in Pakistan utilizes this essential device.
Mercury manometers and aneroid sphygmomanometers are two basic models. Both apply the auscultatory technique with hand blood pressure measurement. Precise use consists of proper arm positioning for BP, slow use of the air release valve, and precise BP cuff placement. Following the correct procedures helps health professionals to avoid BP reading mistakes and their related issues.

History and Evolution of the Sphygmomanometer
Early researchers using glass tubes to track blood flow started blood pressure measuring in the 1700s. The late 1800s brought the first actual sphygmomanometer. It measured systolic against diastolic reading and had a mercury manometer. With cuff inflation and a stethoscope, it grew simpler to use over time. To monitor heart pressure during the cardiac cycle, doctors discovered how to hear Korotkoff phases (I–V).
For safer use, several clinics later replaced mercury with the aneroid sphygmomanometer. Both forms are still in use in Pakistan, particularly for hand BP readings. Modern devices assist in the diagnosis of conditions including white coat hypertension and facilitate ambulatory blood pressure monitoring (ABPM). This development has changed blood pressure recommendations and increased the accuracy of hypertension diagnosis in all age groups.
Key Terms
By providing two values, systolic pressure and diastolic pressure, a sphygmomanometer facilitates blood pressure measurement. The highest number indicates the force of the heart pumping blood called systolic pressure. The lower number, an indication of the pressure when the heart rests, is the diastolic pressure. During manual blood pressure measurement with stethoscope auscultation, these readings, part of the cardiac cycle phases, are heard using Korotkoff sounds.
Blood pressure recommendations state that a typical value is about 120/80 mmHg. Any higher could indicate hypertension, and lower numbers could indicate causes of hypotension. When utilised with appropriate BP cuff placement, arm alignment for BP, and brachial artery palpation, devices including the aneroid sphygmomanometer and mercury manometer produce clear findings. A diagnosis of hypertension in Pakistan depends mostly on regular checks.
Types of Sphygmomanometers
There are several types of sphygmomanometers, each valuable for hand blood pressure reading. The earliest and most exact kind is the mercury manometer. It measures systolic against diastolic readings in a column of mercury. Brachial artery palpation, BP cuff positioning, and stethoscope auscultation all help it to work most effectively. Still, it is less widespread in homes across Pakistan nowadays due to safety issues.
Popular for low cost and safety is the aneroid sphygmomanometer. For home users and clinics, it is perfect because of its dial gauge with a needle. Although they are simple to operate and may lack accuracy, some people choose automatic blood pressure monitors.

How to Use a Sphygmomanometer Correctly
Starting with the cuff on the upper arm, make sure the brachial artery is readily found before properly using a sphygmomanometer. Placed above the brachial pulse, the stethoscope should be roughly one inch above the elbow. Squeeze the bulb to inflate the cuff and guarantee temporary blood flow cut off. Listen then for Korotkoff sounds as the cuff deflates. These noises enable one to ascertain systolic and diastolic pressure.
Then, using the air release valve, gently let off the air. Listening to the Korotkoff sounds, keep close eye on the pressure gauge. The initial sound you hear is systolic pressure, the diastolic pressure shows the absence of the sound. Make sure you maintain relaxed arm position and follow correct blood pressure recommendations. For a correct manual blood pressure reading, make sure the cuff inflation of your aneroid sphygmomanometer or mercury manometer is constant.
Step by Step Procedure
Start by putting the cuff of a sphygmomanometer manually around the upper arm, right above the brachial artery. Using the bulb, inflate the cuff till the blood flow is stopped.
