Age-based differences between mercury sphygmomanometer and pulse dynamic blood pressure measurements.
Both the mercury sphygmomanometer and oscillometric measurement methods are widely in use for pediatric, adult, and geriatric patients. However, inherent differences between the methods of measurement may create varying degrees of sensitivity to age and potentially result in differences between measurements for these two techniques. DESIGN: Measurements of systolic and diastolic blood pressures in 154 subjects were obtained using the mercury sphygmomanometer and pulse dynamic oscillometric methods in accordance with the 1987 Association for the Advancement of Medical Instrumentation guidelines. Subjects were separated into three age groups and their data analyzed for differences between measurements for these two techniques. ⋯ The variation in the agreement of systolic blood pressure measurements can be attributed to the differing effects of age-dependent arterial changes on the measurement methods. The findings indicate that, although the pulse dynamic oscillometric method and mercury sphygmomanometer correlate well when patients of all ages were evaluated as a group, agreement between measurements of systolic blood pressure is dependent on age and the method of measurement employed.

Relationship between ambulatory blood pressure monitoring and response of blood pressure in male hypertensive adolescents to exercise.
High blood pressure in the young has been related to the development of hypertension in adults; hence the importance of identifying adolescents with the risk of developing it. ⋯ Systolic blood pressure measured by ambulatory blood pressure monitoring is related to response of systolic blood pressure to exercise and ambulatory blood pressure monitoring can identify groups of subjects at greater than normal risk through their higher blood pressure during sleep. Greater than normal blood pressure variability in adolescents is an indicator of the risk of reaching abnormal exercise values of systolic blood pressure. Higher casual blood pressure than ambulatory blood pressure monitoring values for adolescents should be considered abnormal.
