Why is the sphygmomanometer kept at the level of your heart while measuring your blood pressure?

If it is below your heart then the reading could be falsely high; if it is too high, falsely low. This is due to the hydrostatic component of the blood pressure, which is due to gravity and varies only with the height of the point being measured (in a standing position lowest at the head, highest at the feet). When measuring blood pressure it is desirable to have the same hydrostatic component as at the heart. Therefore, by convention, the "right" blood pressure is the one taken at the heart level. Please note that a 10 cm difference in level between the point of measure and the heart would introduce an error of 7.6 mmHg.

What is the working principle of a spygmomanometer?
The sphygmomanometer is designed to monitor blood pressure by measuring the force of the blood in the heart where the pressure is greatest. This occurs during the contraction of the ventricles, when blood is pumped from the heart to the rest of the body (systolic pressure). The minimal force is also measured. This occurs during the period when the heart is relaxed between beats and pressure is lowest (diastolic pressure).
How does sphygmonamometer work?
A sphygmomanometer is a device which measures blood pressure. It works by reading both the systolic, which is the peak pressure as the heart contracts, and diastolic, which is the lowest pressure as the heart relaxes.
How do blood pressure regulators detect high blood pressure?
Each time the heart contracts a sound is heard, a gauge on the sphygmomanometer measures the pressure that blood exerts during ventricle contraction.
If a sphygmomanometer were used would it result give the pressure of the heart?
A sphygmomanometer is used to measure blood pressure.
An instrument for measuring blood pressure?
The instrument used to measure blood sugar is usually reffered to as a blood glucose meter, or a BSGM (Blood Sugar Glucose Meter).
What is systolic pressure measured?
The pressure inside the blood vessels at the end of the contraction of the heart. Diastolic pressure is the pressure between beats when the heart is relaxed. Blood pressures are systolic/diastolic; 120/80.
What are the instruments used to determine the pressure of the heart?
The pressure of the heart is generally referred to as blood pressure. It is measured by a blood pressure cuff and stethoscope by a nurse or a doctor. There is also another device that many people use, usually found in a drug store that is automatic, and it is called a sphygmomanometer. What these devices measure is the blood pressure coming out of the left ventricle of the heart.
What is blood pressure measured with?
Usually, with the use of a device to measure blood pressure, called a sphygmomanometer. Measuring pressure invasively, by penetrating the arterial wall to take the measurement, is much less common and usually restricted to a hospital setting.
What sound get between systolic and diastolic blood pressure?
If you are manually taking a blood pressure measurement using a sphygmomanometer and stethoscope, the sounds you hear between the systolic and diastolic blood pressure are called Korotkoff sounds, and they are muffled "whooshing" sounds heard with each heart beat and are thought to be caused by turbulent blood flow through the blood vessel caused by partial occlusion by the cuffed sphygmomanometer.
What is the use of the sphygmomanometer?
It is a device for measuring blood pressure.A sphygmomanometer (often condensed to sphygmometer) or blood pressure meter is a device used to measure blood pressure, comprising an inflatable cuff to restrict blood flow, and a mercury or electronic manometer to measure the pressure. The pressure is stated as two numbers, the highest pressure that blood reaches (pushes past the cuff) and the lowest (the flow is unimpeded and flows without being pushed by the heart contraction). Manual sphygmomanometers are used in conjunction with a stethoscope to determine the two pressures.The higher pressure is the systolic (heart pushing), the lower the diastolic. Blood pressure is stated as both of these numbers, e.g. 115/75 spoken "115 over 75" is a systolic pressure of 115 (mm Hg), a diastolic of 75 (mm Hg).
What is disatolic?
When measuring blood pressure, this is the lower number. It is the pressure in the heart as it rests between beats.
When a doctor take your blood pressure what is being measuring?
The pressure exerted against the walls of the arteries as the heart pumps; and again as the heart rests.
