For example, if a person’s actual blood pressure is 134, and blood pressure is measured on a dangling arm, the reading could end up over 140, which is considered to be stage 2 hypertension.
“When the arm is either in the lap or at the side, the blood vessels in the arm are at a greater vertical distance from the heart. Gravity increases the pressure in these blood vessels.
New research shows that different arm positions can produce different blood pressure readings. Blood pressure readings taken when an arm is resting on a hard surface are slightly lower than when ...
In pregnancy, it is the fetal heart and not the mother's heart that builds up the fetal blood pressure to drive blood through the fetal circulation. The blood pressure in the fetal aorta is approximately 30 mmHg at 20 weeks of gestation, and increases to approximately 45 mmHg at 40 weeks of gestation. [27]
Blood pressure is recorded as two readings: a higher systolic pressure, which occurs during the maximal contraction of the heart, and the lower diastolic or resting pressure. [11] In adults, a normal blood pressure is 120/80, with 120 being the systolic and 80 being the diastolic reading. [12] Usually, the blood pressure is read from the left ...
A sphygmomanometer (/ ˌ s f ɪ ɡ m oʊ m ə ˈ n ɒ m ɪ t ə r / SFIG-moh-mə-NO-mi-tər), also known as a blood pressure monitor, or blood pressure gauge, is a device used to measure blood pressure, composed of an inflatable cuff to collapse and then release the artery under the cuff in a controlled manner, [1] and a mercury or aneroid manometer to measure the pressure.

The first fully automated oscillometric blood pressure cuff called the Dinamap 825, an acronym for "Device for Indirect Non-invasive Mean Arterial Pressure", was made available in 1976. [18] It was replaced in 1978 by the Dinamap 845 which could also measure systolic and diastolic blood pressure, as well as heart rate. [19]
