Pseudohypertension, also known as pseudohypertension in the elderly, noncompressibility artery syndrome, and Osler's 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.

To perform the test, 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".

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.
