How is blood pressure measured using a sphygmomanometer?
Blood pressure is measured using a sphygmomanometer, or blood pressure monitor. It consists of an inflatable cuff that’s wrapped around your arm, roughly level with your heart, and a monitoring device that measures the cuff’s pressure. The monitor measures two pressures: systolic, and diastolic.
What is the instrument’s used to measure blood pressure?
To measure blood pressure, your doctor uses an instrument call a sphygmomanometer, which is more often referred to as a blood pressure cuff. The cuff is wrapped around your upper arm and inflated to stop the flow of blood in your artery.
What is the principle of sphygmomanometer?
All sphygmomanometers rely on the principle that when a cuff containing a hollow rubber air bladder is wrapped around a limb and the cuff is inflated, the pressure in the bladder is equal to the pressure on the artery under the cuff.
What are the steps in using sphygmomanometer?
How to Use Sphygmomanometers
- Know your basic knowledge of blood pressure readings. Blood pressure readings are expressed as systolic over diastolic pressure.
- Use proper-sized cuffs.
- Properly place the cuff on the arm.
- Position the stethoscope.
- Inflate the cuff.
- Listen and observe.
- Repeat the procedure on the other arm.
What are parts of sphygmomanometer?
Parts of sphygmomanometer
- Bladder: This is an inflatable bag that is used to compress the arm to occlude the artery.
- Cuff: This is designed to hold the bladder around the arm during the measurement.
- Manometer: This is a device used to measure the air pressure in mmHg.
Who discovered sphygmomanometer?
In 1881, von Basch created the sphygmomanometer and the first non-invasive BP measurements. However, in 1896, Scipione Riva-Rocci developed further the mercury sphygmomanometer, almost as we know it today. The sphygmomanometer could only be used to determine the systolic BP.
What are the types of sphygmomanometer?
Following are the three major types of sphygmomanometer: Mercury sphygmomanometer: It is the most conventional form of blood pressure apparatus and is considered to be the golden standard….Types of sphygmomanometer
- Pocket-aneroid sphygmomanometer.
- Palm aneroid sphygmomanometer.
- Clock-style aneroid sphygmomanometer.
What is the importance of using sphygmomanometer?
The indirect blood pressure measurement with mercury sphygmomanometers has been shown to be valuable in several clinical circumstances. Their extensive use has allowed the collection of the necessary evidence to identify arterial hypertension as a major risk factor for cardiovascular diseases.
