Aneroid Sphygmomanometer (palm type)

From the moment you step foot into a doctor's office, you can expect one of the first diagnostic tools to be used is the Palm Aneroid Sphygmomanometer. This handy device quickly and accurately measures your blood pressure and provides essential information about your health. But what is this device and how does it work? Read on to find out the whole story of the Palm Aneroid Sphygmomanometer.

History of Palm Aneroid Sphygmomanometer

The Palm Aneroid Sphygmomanometer is a blood pressure measuring device that has been used for over 100 years. It is a simple, yet accurate way to measure blood pressure and is still in use today. The Palm Aneroid Sphygmomanometer was first invented in 1881 by Dr. Karl Vierordt. It was originally designed as a more comfortable alternative to the mercury sphygmomanometer, which was the standard at the time. The new design was much easier to use and more portable, making it ideal for use in doctors’ offices and hospitals. Over the years, the Palm Aneroid Sphygmomanometer has undergone some changes, but its basic design remains the same. Today, it is still one of the most popular blood pressure measuring devices available and is used by millions of people around the world.

Why does a doctor use an Aneroid Sphygmomanometer?

Aneroid sphygmomanometers are the most commonly used type of blood pressure readings. They are easy to use and relatively inexpensive. Aneroid sphygmomanometers work by measuring the force with which your heart pumps blood through your arteries. The higher the force, the higher your blood pressure. Doctors use aneroid sphygmomanometers because they are quick and easy to use, and they provide an accurate reading of your blood pressure.

How Does the Aneroid Sphygmomanometer Work?

The aneroid sphygmomanometer is a device that is used to measure blood pressure. It consists of a cuff that is placed around the arm and inflated, a mercury column that is used to measure the pressure, and a stethoscope. The mercury column is connected to the cuff by a tube. The cuff is inflated until the mercury column is at the level of the heart. The stethoscope is used to listen to the heart beat. The blood pressure is then read from the mercury column.

What are the different types of Aneroid Sphygmomanometers?

Aneroid sphygmomanometers come in a variety of shapes and sizes, but they all have one thing in common: they measure blood pressure. There are two types of aneroid sphygmomanometers: manual and automatic. Manual aneroid sphygmomanometers are the most common type. They consist of a cuff that is placed around the upper arm and inflated with a hand pump. The cuff is then released and the mercury column in the gauge is allowed to fall. The systolic pressure (the top number) is read when the first sound is heard, and the diastolic pressure (the bottom number) is read when the sounds disappear. Automatic aneroid sphygmomanometers are similar to manual ones, but they have an electronic cuff that inflates automatically. They also have a digital display that shows the blood pressure readings.

How do you read your blood pressure from an Aneroid Sphygmomanometer?

In order to read your blood pressure from an Aneroid Sphygmomanometer, you will need to take the following steps:


1. Place the cuff around your upper arm, making sure that the bottom of the cuff is level with your heart.


2. Pump the cuff until it is tight enough to constrict your blood flow. You should feel your pulse in your fingers while doing this.


3. Slowly release the pressure in the cuff while listening for your pulse with a stethoscope.


4. As you listen, note the point at which you first hear your pulse and then note the point at which it disappears. The difference between these two points is your systolic blood pressure.


5. Continue releasing the pressure until you can no longer hear your pulse. This is your diastolic blood pressure.


The lowly, unglamorous sphygmomanometer or blood pressure cuff is the quiet workhorse of the doctor's office, clinic, or hospital. It measures a person's blood pressure. The word, sphygmomomanometer comes from the Greek "sphygmos" (pulse) and the scientific term manometer (pressure meter.) This medical device was invented in 1881 by Samuel Siegfried Karl Ritter von Basch, an Austrian physician. The sphygmomanometer has worked very simply from it's invention to the present. It is made up of a closeable arm band with an inflatable bladder, with a tube leading to a bulb used as a pump. The bulb has a stopper valve so air will not escape prematurely. There are many variations in sphygomanometers but the basic function is the same. The idea is to block the blood flow in the arm and to check the readings when the air is slowly released to measure the pressures. The blood pressure, simply stated, is the stress placed on the walls of the blood vessels and the heart chambers by the flow of blood. The arterial pressure, measured by the sphygmomanometer is a measure of how much blood the heart pumps and the resistance in the arteries. The Mayo Clinic lists a normal blood pressure as 120/80. No one has that reading every time a reading is taken. Many factors effect a blood pressure like: time of day, level of exercise, stress level, many diseases and some medications. In a normal, healthy person, when the blood vessels are constricted such as: after a cup of coffee, a stressful situation or physical activity, the pressure in the vessels will be higher. In a relaxed state with the heart beating slowly and the blood vessels dilated such as after a nap or a quiet evening at home, the pressure in the vessels should be lower. A single high blood pressure reading is not a disease. It takes a series of high readings to determine if a patient has hypertension. A sphygmomanometer works by reading two pressures, or Korotkoff sounds. These two sounds are: a systolic, for heart systole or period of contraction when the heart pumps blood into the system, and a diastolic, for diastole or period of time when the heart relaxes and fills up again. The blood pressure is usually taken with the patient either sitting or lying down. The cuff is wrapped around the upper arm and secured with the velcro fasteners. The bell of the stethoscope is placed over the artery in front and to the inside of the elbow. The cuff is then inflated with the bulb to the point that stops the flow of blood to the arm. The air is released slowly. The first sound heard is the systolic pressure. This happens when the cuff pressure is less than the pressure of the blood in the artery. As the cuff further deflates, when the sound quits is the diastolic pressure. The difference between the two is the pulse pressure, representing the force that your heart generates each time it contracts or beats. The best sphygmomanometer to use depends totally what it is used for. They can be manual or electronic. The most accurate is the mercury sphygmomanometer. It measues blood pressure by observing the height of a column of mercury. It is fragile and must be attached to something sturdy. The most commonly used is the aneroid sphygmomanometer. It is less accurate but more portable for wider use. It measures blood pressure on a dial. Digital sphygmomanometers are growing in use. They are the least accurate because they calculate the pressure rather than reading it off of a scale. The cuff in a digital sphygmomanometer can be wrapped around an upper arm, a wrist or a finger, depending on which one you have. These require very little instruction and are best for use in the home on the same person all the time. High tech, fully automated sphygmomanometers are used in intensive care units, operating rooms and recovery rooms for continuous monitoring of blood pressures in critically ill patients. Manual, hand pump sphygmomanometers are used in hospitals and outpatient clinics to get routine blood pressures. Only manual sphygomanometers require the use of a stethoscope. However you measure it, your blood pressure is important. Everyday more people are diagnosed with hypertension without realizing they have it. If you find out that your pressure is high, see your doctor for diagnosis and treatment. Many things can cause hypertension. Most are very treatable.
