millimeters of mercury (mmHg)
Yes it can with an automatic b/p cuff however a blood pressure taken in the arm (assuming there are no problems like past stroke or dialysis shunts) is usually more accu…rate.
Blood pressure is measured in a fraction form: x/y, where x is the systolic pressure, or pressure when the heart is beating and y is the diastolic pressure, or the pressure wh…en the heart is at rest. normal blood pressure is considered to be 120/80 inches of mercury (in Hg.) The difference in these two numbers is the pulse pressure, which is basically how hard your heart is working. Blood pressure is measured with a device called a sphygmomanometer.
mmHg ( millimetres of mercury)
High blood pressure or hypertension can be an acute problem. The heart muscle enlarges and can become weaker over time. Hypertension is one of the risk factors for strokes, he…art attacks, heart failure, and renal failure. Low blood pressure or hypotension can cause decreased blood supply to the brain and shock. Other causes of low blood pressure or hemorrhage, sepsis, and toxins.
I always thought, being a railroad buff and familiar with PSI, that it was in Pounds per square inch. Some Path cars ran a standing pressure in the brake system- Main over equ…alizing, of ll0/70, exactly l0 pounds below the Human norms, the joke was the M-58 cars are a little anemic ( this was compressed air, to operate the brakes) Alas it is ( Blood pressure) actually in MM/Mercury ( Mercury column gauges are still in use, in some quarters) and NOT PSI. People still say (pounds) as it is a sort of flag of convenience, like the confusion of (Two Blocked) with Half Mast in reference to flag usage. Two Blocked originally meant the Flag was ALL the way up- touching the blocks of the pulleys. By some popular misunderstanding- as with the Blood Pressure, as Half is l/2 l over Two- somehow people will say ( the Flag was Two-Blocked for President Kennedy) for example, when they mean Half-Mast. so it goes.
use a blood pressure machine
I don't really know what you're getting at with this question. Blood pressure is measured with three numbers, systolic, diastolic, and pulse rate. Systolic pressure measures t…he blood being pumped through the heart when it contracts, where diastolic measures the relaxation of the heart muscle to allow blood to fill the chambers. Puls rate is how many contract-relax cycles happen in one minute. Hope this helps...
it is measure by a sphygmomanometer
Blood pressure is the measure of the force of the blood against the walls of the blood vessels that it is contained in. Blood pressure is usually expressed in mmHg as the syst…olic pressure divided by the diastolic pressure.
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 person's blood pressure is measured by systolic and diastolic readings from a blood pressure monitor. Systolic blood pressure measures the pressure of the blood traveling t…hrough the artery while the heart has contracted (usually around 180), while diastolic blood pressure measures the pressure of blood traveling through arteries when the heart has released (usually around 80)
We measure the pressure that is exerted by the blood on the wall of vessels.
