Portsmouth sign refers to a situation in which the systolic blood pressure (SBP) reading (measured in mmHg) falls below that of the heart rate (HR) (measured in beats per minute). It typically signifies a worrying clinical prognosis, specifically caused by shock .

The pulse is the rate at which the heart beats while pumping blood through the arteries, recorded as beats per minute (bpm). [11] It may also be called "heart rate". In addition to providing the heart rate, the pulse should also be evaluated for strength and obvious rhythm abnormalities. [11] The pulse is commonly taken at the wrist (radial ...
When Dr. Oz sat Rachael Ray down for a blood pressure test during a segment of her show, he wasn't entirely pleased with the numbers he saw. ... pressure is supposed to be under 140 over 90 ...
Hypotension, also known as low blood pressure, is a cardiovascular condition characterized by abnormally reduced blood pressure. [1] Blood pressure is the force of blood pushing against the walls of the arteries as the heart pumps out blood [2] and is indicated by two numbers, the systolic blood pressure (the top number) and the diastolic blood pressure (the bottom number), which are the ...
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 ...
Orthostatic vital signs are also taken after surgery. [7] A patient is considered to have orthostatic hypotension when the systolic blood pressure falls by more than 20 mm Hg, the diastolic blood pressure falls by more than 10 mm Hg, or the pulse rises by more than 20 beats per minute within 3 minutes of standing [5] [7]
Rates vary by age with extremely rare for those under the age of 11 and extremely common in those older than 75 years. [28] These differences may be due to rates of high blood pressure and atherosclerosis, which are more easy to find in older persons. [29]
