Too-tight blood stress cuffs could cause “strikingly inaccurate” readings and a misdiagnosis of hypertension for adults with bigger arms, a Johns Hopkins University examine has discovered.
Six Johns Hopkins researchers revealed the examine Monday in JAMA Internal Medicine. They examined 195 adults from Baltimore with a imply age of 54 and a variety of arm sizes who volunteered for 4 units of blood stress readings utilizing too-small, too-large and appropriately sized cuffs.
The examine discovered members with smaller arms bought a 3.6 millimeters of mercury decrease systolic blood stress studying from the regular-sized cuff utilized in many medical doctors’ workplaces and residential blood stress machines than from their appropriate dimension.
Adults requiring a big or extra-large cuff had 4.8 mm Hg and 19.5 mm Hg increased blood stress readings from the common cuff, respectively, than from their appropriate sizes.
“Many office triage measurements occur without individualized cuff selection, and most home [blood pressure] devices come with one cuff size,” Dr. Tammy Brady, co-author of the examine and director of the pediatric hypertension program at Johns Hopkins Children’s Center, informed The Washington Times.
Earlier research didn’t quantify the affect of the improper cuff sizes on blood stress readings and associated diagnoses, she famous.
In probably the most putting instance from the examine, members who required an extra-large cuff measured their blood stress at a mean of 125/79 with the right-sized cuff, an elevated studying. When the identical adults used a regular-sized cuff that was two sizes too small, they scored a mean blood stress studying of 144/87, a stage two hypertension studying.
According to different information cited within the examine, solely 74% of medical college students underneath statement selected the correct cuff dimension for measurements.
The researchers urged medical doctors, nurses and adults measuring their blood stress at house to pay nearer consideration to the cuffs they use, particularly for individuals with bigger arms who may get misdiagnosed with stage one or two hypertension.
“Individuals with an incorrect hypertension diagnosis could experience undue stress, incur expense, undergo unnecessary testing and receive overtreatment, which could lead to side effects and adverse events,” Dr. Brady mentioned. “Conversely, when a loo-large cuff is used, hypertension could be missed, leading to missed opportunity for treatment and prevention of [cardiovascular disease].”
