Normally, doctors measure blood pressure in every patient using a standard, medium-sized cuff. A new study warns that this can lead to misinterpretation. The use of conventional blood pressure cuffs in doctors' offices has come under criticism because they provide "obviously inaccurate" readings, especially for patients with different arm sizes. This was found in a recent study from Johns Hopkins University School of Medicine, published in the journal JAMA Internal Medicine. Accurate blood pressure readings are important for diagnosing conditions such as hypertension, a leading cause of heart disease. Although clinical guidelines recommend one cuff size for each arm, physicians often use mid-sized cuffs, which can lead to inaccuracies.
