The barometer is the instrument that is used to measure the air 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.
The instrument used to measure air pressure is barometer. It is a scientific instrument used in meteorology to measure atmospheric pressure.
There are several options depending on the type of air pressure being measured: To measure atmospheric (ambient air) pressure, a barometer is used. For tire…s, it's a tire pressure gauge. In industrial processes and boilers it is frequently called a manometer For pressure vessels it is a Bourdon gauge
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 pre…ssure 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.
A stethoscope is the device used to allow a medical (or other) technician or professional to listen to the internal body sounds. Links can be found below.
I think it is a barometer and aneroid barometer
The instrument that is used to measure atmospheric pressure would be a Barometer.
A barometer is used to measure atmospheric pressure. It can also measure altitude!
A barometer is one. That's all I know. I have homework to do regarding 2 instruments to measure air pressure.
There are several options depending on the type of air pressure being measured: In the 1800's ships used a weather glass - a simple barometer - to measure cha…nges in air pressure. To measure atmospheric (ambient air) pressure, a barometer is used. (It may be either an aneroid or a mercury type of barometer.) For tires, it's a tire pressure gauge. In industrial processes and boilers the gauge is frequently called a manometer. For pressure vessels it is a Bourdon gauge.
The BP is expressed in systolic pressure over diastolic pressure in millimeters of mercury (mmHg).
