A manual blood pressure cuff, also known as a sphygmomanometer, is a medical device used to measure a person’s blood pressure. It consists of three main components:
Cuff: The cuff is a flexible and inflatable sleeve typically made of nylon or similar material. It is wrapped around the upper arm and tightened to apply pressure to the brachial artery, which is the major artery in the arm used to measure blood pressure.
Inflation bulb: The inflation bulb is connected to the cuff and is used to pump air into the cuff to increase the pressure around the arm, temporarily cutting off blood flow to the brachial artery.
Pressure gauge: The pressure gauge is attached to the cuff and displays the pressure in millimeters of mercury (mmHg). When the cuff is inflated, the gauge indicates the pressure exerted on the artery. The healthcare provider or user can then release the air gradually from the cuff while listening for specific sounds (Korotkoff sounds) through a stethoscope placed over the brachial artery. The point at which the sounds start and stop corresponds to the systolic and diastolic blood pressure readings, respectively.
Manual blood pressure cuffs require proper technique and training to obtain accurate readings. They are commonly used in medical settings like hospitals, clinics, and doctor’s offices and are sometimes preferred due to their reliability and cost-effectiveness compared to automated blood pressure monitors.

What is Manual Blood Pressure Cuff
A manual blood pressure cuff, also known as a sphygmomanometer cuff, is a medical device used to measure a person’s blood pressure. It is a fundamental tool in healthcare settings and is widely used by medical professionals, nurses, and other healthcare providers. The manual blood pressure cuff consists of three main components:
Cuff: The cuff is a flexible and inflatable sleeve, typically made of nylon or similar materials. It is wrapped around the upper arm and secured in place to apply pressure to the brachial artery, which is the major artery in the arm used to measure blood pressure.
Inflation Bulb: The inflation bulb is connected to the cuff by tubing. It is used to pump air into the cuff, which increases the pressure around the arm, temporarily stopping blood flow to the brachial artery.
Pressure Gauge: The pressure gauge is attached to the cuff and displays the pressure in millimeters of mercury (mmHg). As the cuff is inflated, the gauge indicates the pressure exerted on the artery. The healthcare provider or user slowly releases the air from the cuff while listening for specific sounds (Korotkoff sounds) using a stethoscope placed over the brachial artery. The point at which the sounds start and stop corresponds to the systolic and diastolic blood pressure readings, respectively.
Manual blood pressure cuffs require proper technique and training to obtain accurate readings. They are commonly used in medical settings like hospitals, clinics, doctor’s offices, and ambulances. They are also used at home for monitoring blood pressure. Properly measuring and monitoring blood pressure is crucial for diagnosing and managing various health conditions, such as hypertension (high blood pressure) and hypotension (low blood pressure).
It’s worth noting that automated blood pressure monitors have become increasingly popular and are more user-friendly for some individuals. However, manual blood pressure cuffs are still widely used due to their reliability, cost-effectiveness, and ability to provide accurate readings when used correctly.

Use Palpation to Estimate the Systolic Blood Pressure
Palpation is a technique used to estimate the systolic blood pressure by feeling for the pulse in the artery while gradually inflating the manual blood pressure cuff. This method is commonly used as an initial approximation before using the auscultatory method (listening for Korotkoff sounds) to obtain a more accurate blood pressure measurement.
Here’s how to use palpation to estimate the systolic blood pressure:
Prepare the patient: Position the patient comfortably, and expose their upper arm for the blood pressure measurement. Make sure the patient is relaxed and in a sitting or lying position.
Locate the brachial artery: The brachial artery is located on the inner side of the upper arm, slightly above the elbow crease. Use your fingers to palpate (feel) for the pulsations of the artery.
Inflate the cuff: Place the blood pressure cuff on the upper arm, ensuring it is snug but not too tight. Use the inflation bulb to gradually inflate the cuff, increasing the pressure around the arm.
Monitor for pulse obliteration: As you inflate the cuff, keep your fingers on the brachial artery, and continue feeling for the pulse. As the cuff pressure increases, you will feel the pulsations diminish (palpation pulse obliteration) as the blood flow to the arm is restricted.
Deflate the cuff: Gradually release the air from the cuff while keeping your fingers on the artery. As the pressure in the cuff decreases, you will feel the pulsations return. The point at which you first feel the pulse returning is an estimation of the systolic blood pressure.
It’s important to note that palpation is not as accurate as using the auscultatory method, but it can provide a rough estimate of the systolic blood pressure. Once you have this approximate value, it’s recommended to use the auscultatory method with a stethoscope to obtain a more precise blood pressure measurement, including the diastolic reading. This will ensure a more reliable assessment of the patient’s blood pressure.
When purchasing a manual blood pressure cuff, it’s essential to consider several factors to ensure you get a reliable and suitable device for your needs. Here is a buying guide to help you make an informed decision:
Accuracy: Accuracy is paramount when measuring blood pressure. Look for cuffs that have been clinically validated for accuracy. Reliable brands often provide this information in their product descriptions or packaging.
Cuff Size: The cuff size should fit your arm circumference properly to ensure accurate readings. Most cuffs are available in different sizes, so measure your upper arm’s circumference and choose the appropriate size accordingly.
Durability and Quality: Check the build quality and materials of the cuff, as it needs to withstand frequent use without wearing out quickly. Look for cuffs made of durable materials like nylon or latex-free options.
Easy-to-Read Gauge: The pressure gauge should have large, clear markings, making it easy to read the blood pressure measurements accurately.
Inflation System: Make sure the inflation bulb is comfortable to use and allows for precise inflation and deflation control.
Aneroid vs. Mercury: Manual blood pressure cuffs are available in two main types – aneroid and mercury. Aneroid cuffs use a dial gauge for pressure readings, while mercury cuffs use a column of mercury. Both types are accurate, but some healthcare facilities prefer mercury cuffs due to their historical accuracy and reliability.
Calibration: Check if the cuff comes with calibration instructions or a calibration tool to ensure accurate readings over time.
Stethoscope Compatibility: If you already have a stethoscope, ensure that the cuff you choose is compatible with it. Some cuffs may include a stethoscope as part of a kit.
