Pseudohypertension, also known as pseudohypertension in the elderly, noncompressibility artery syndrome, and Osler's sign (or Osler sign) of pseudohypertension is a falsely elevated blood pressure reading obtained through sphygmomanometry due to calcification of blood vessels which cannot be compressed.[1] There is normal blood pressure when it is measured from within the artery.[2] This condition however is associated with significant cardiovascular disease risk.[2]

Because the stiffened arterial walls of arteriosclerosis do not compress with pressure normally, the blood pressure reading is theoretically higher than the true intra-arterial measurement.[citation needed]

To perform the test (also named Osler maneuver), one first inflates the blood pressure cuff above systolic pressure to obliterate the radial pulse. One then attempts to palpate the radial artery, a positive test is if it remains palpable as a firm "tube".[citation needed]

It occurs frequently in the elderly irrespective of them being hypertensive, and has moderate to modest intraobserver and interobserver agreement.[3] It is also known as "Osler's maneuver".[4][5]

The sign is named for William Osler.

Osler sign occurs due to Monckeberg's sclerosis of arteries. Unlike atherosclerotic change in the intimal layer of arterial lumen, It is the calcification in the media of small or mediate-size arteries within four limbs. Sometimes it also affects renal and coronary arteries. On X-ray, it shows "rail-tracking" appearance. Clinically, pseudohypertension should be considered once one develops dizziness without lowering blood pressure after he/she starts or escalates antihypertensive agents. [6]
