It's closest to the heart, the reading is better. That's partially why heart attack victims feel pain in the left arm.
No. Use the other arm or lower extremities if it's appropriate.
When there's a port or shunt in the arm blood pressure is contraindicated on that arm.
Yes. I get blood taken out of my arm and put back in through the fistula for "Dialysis".
It should be positioned on the upper arm just above the crease of the lower arm.
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 accurate.
basicallyit is the closest point to the heart it can be mesared so ideal should be left arm, as blood pressure is a direct measment of force of the heart, presure will be lost further away from heart, the measured position is also for a convience as the atery in arm lies closer to the surface so restricting this artery and listening for the Korotkoff sound to measure the pressure is easier.
No, taking blood pressure in the leg is not the same as taking it in the arm. Blood pressure is typically measured in the arm because it provides a good reflection of overall systemic blood pressure. Taking blood pressure in the leg can be done in certain medical situations, but the values may differ from those obtained in the arm.
0.2 L
There is the blood pressure cuff which wraps around the arm and the pressure guage I believe is called a "sphygmomanometer"
A superficial vein on the medial of the of the arm called the Cephalic vein. Of course blood can be taken from just about any visible vein nowadays but that is the best candidate for the large volume taken when donating blood.
yes blood is still flowing
Not in arm, over arm. I detects your blood pressure when used by a trained person with a stethoscope.
