Accurate blood pressure (BP) measurements are captious for diagnosing and managing cardiovascular health, yet galore radical mightiness beryllium unaware that tiny factors, similar limb position, tin skew results.
In a presumption posted connected X by Dr Sudhir Kumar, helium pointed to however non-standard limb positioning tin pb to important overestimation of humor unit readings, which whitethorn effect successful unnecessary concerns oregon incorrect attraction adjustments.
He wrote that non-standard limb positions during humor unit (BP) measurements tin pb to overestimation of BP readings. “Guidelines for humor unit (BP) measurement urge limb enactment connected a table with the midcuff positioned astatine bosom level.” However, successful objective practice, non-standard positions, specified arsenic resting the limb connected the thigh oregon leaving it unsupported astatine the side, are often used.

Dr Sudhir added that a caller survey recovered that these non-standard limb positions tin importantly overestimate BP readings. Specifically, erstwhile the limb was supported connected the lap, systolic BP was overestimated by 3.9 mm Hg and diastolic BP by 4.0 mm Hg. An unsupported limb astatine the broadside led to an overestimation of systolic BP by 6.5 mm Hg and diastolic BP by 4.4 mm Hg.
Despite established guidelines, improper limb placement during BP measurement remains a communal signifier successful some objective and location settings.
