Instrument used to listen to sounds of the blood during blood pressure measurements?
Strange. Normaly when you hear thumping sounds its your heart beat and that can be due to high blood pressure.
The Brachial artery on the inside of the elbow is most commonly used because it can be accessed easily and compressed with a cuff. However it does depend on what method you ar…e using. With use of sphygmomanometer (inflated cuff compresses artery) you can use the brachial or the radial (at the wrist - the same as commonly used for taking the pulse). This gives less reliable results. (Some monitors even use the digital arteries in the finger). Invasive methods in which the pressure is measured directly by passing a sensor into directly the artery are often used during surgical or invasive procedures. In such cases larger deeper seated arteries are used (eg Subclavian - behind the collarbone or femoral - in the groin) as well as the brachial or radial arteries.
A sphygmometer. (pronounced sfig- mo- met -er)
mm Hg (milimeters of mercury) usually measured with a Stethoscope and a sphygmomanometer .
The BP is expressed in systolic pressure over diastolic pressure in millimeters of mercury (mmHg) .
a Sound Pressure Level Meter is used to measure sound levels. See related link.
A Blood Pressure cuff and stethoscope are used to determine BP.
Most commonly, a stethoscope is used to listen to an apical pulse, and in combination with a sphygmomanometer (blood pressure cuff) the stethoscope is used to measure blood pr…essure.
They call it a Sphygmomanometer . (Sphyg mo manometer.) The word derives from the Greek for pulse, Sphyg. and Manometer for a pressure meter. For traditional reasons, the …pressure is still measured in the equivalent height of a column of mercury. Which is what was used originally in the manometer. inHg (Inches of mecury) The sphygmomanometer works by balancing air-pressure in an inflated cuff against the pulse pressure in the arm. A pressure gauge attached to the cuff indicates the pressure. The cuff is placed on the upper arm and then inflated. The pulse is listened to, using a stethoscope. The point at which the pulse can no longer be heard, is when the pressure of the cuff cuts off the blood supply and gives the upper reading, called the systolic. Then the pressure of the cuff is slowly released and the pulse listened to. The lowest pressure when the pulse can no longer be heard, is the Diastolic. This gives the two pressures of the heart, during a beat, at maximum pressure and when relaxed. These functions can be built into a machine, which uses a microphone to listen and an electric pump to control the cuff pressure. The computer displays the result on an LCD screen. The device was invented by Samuel Siegfried Karl Ritter von Basch in 1881. Scipione Riva-Rocci introduced a more easily used version in 1896. Harvey Cushing discovered this device in 1901 and popularized it.
Your heart beat
The Brachial artery in the arm is most commonly used to measure BP.
It is a mouthful: sphygmomanometer. It is 6 syllables. SPHYG-mo-ma-NO-me-ter. The sphyg syllable (SFIG) starts with an uncommon SF sound. You just go from the non-vocalized s …sound to the non-vocalized f sound, and then go on.
