[3] [4] This sign may also be observed as a symptom of hyperventilation syndrome as a result of hypocapnia-induced reduction of calcium levels in the blood. [ 5 ] To elicit the sign, a blood pressure cuff is placed around the arm and inflated to a pressure greater than the systolic blood pressure and held in place for 3 minutes.
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.

Normal blood pressure is defined as less than 120 systolic pressure and less than 80 diastolic. Stage 1 high blood pressure is when systolic is 130 to 139 or diastolic is 80 to 89.
A new study found using only one size of a blood pressure cuff for any and all patients could lead to highly inaccurate readings.
A 2019 study also found that disrupted sleep was more likely to cause spikes in blood pressure during the evening, as well as the day after. Chronic stress can also lead to an increased risk.
It is therefore recommended to palpate and auscultate when manually recording a patient's blood pressure. [3] Typically, the blood pressure obtained via palpation is around 10 mmHg lower than the pressure obtained via auscultation. In general, the examiner can avoid being confused by an auscultatory gap by always inflating a blood pressure cuff ...
The blood pressure cuff should be positioned at mid-heart level. The patient’s feet should be flat on the floor, with the back supported. Nearly half of U.S. adults have high blood pressure, ...
If the heart is stopped, blood pressure falls, but it does not fall to zero. The remaining pressure measured after cessation of the heart beat and redistribution of blood throughout the circulation is termed the mean systemic pressure or mean circulatory filling pressure; [48] typically this is proximally ~7 mmHg.
