As the pressure in the cuff is the same as the pressure produced by the heart, some blood will be able to pass through the upper arm when the pressure in the artery rises during systole. This blood flows in spurts as the pressure in the artery rises above the pressure in the cuff and then drops back down beyond the cuffed region, resulting in ...
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 arm unless there is some damage to the arm. The difference between the systolic and diastolic pressure is called the pulse pressure.

In medicine, the mean arterial pressure (MAP) is an average calculated blood pressure in an individual during a single cardiac cycle. [1] Although methods of estimating MAP vary, a common calculation is to take one-third of the pulse pressure (the difference between the systolic and diastolic pressures), and add that amount to the diastolic pressure.
Pulse pressure is quantified using a blood pressure cuff and stethoscope (Korotkoff sounds), by measuring the variation of the systolic pressure during expiration and inspiration. [8] To measure the pulsus paradoxus, place a blood pressure cuff on the patient's arm and very slowly deflate the cuff while listening for brachial pulsations.
The improper interpretation of this gap may lead to blood pressure monitoring errors, [1] [2] such as an underestimation of systolic blood pressure and/or an overestimation of diastolic blood pressure. In order to correct for an auscultatory gap, the radial pulse should be monitored by palpation. [3]
The end diastolic pressure of the right ventricle can measured directly with a Swan-Ganz catheter. For the left ventricle, end diastolic pressure is most commonly estimated by taking the pulmonary wedge pressure, which is approximately equal to the pressure in the left atrium when the lungs are healthy. When the heart is healthy the diastolic ...
