  • Look Inside

A new portable device for the indirect measurement of ambulatory blood pressure in the finger was success-fully applied for diagnostic, physiologic, and clinical pharmacologic study in 500 hypertensives. The device, equipped with a microprocessor, permits long-term ambulatory monitoring of indirect systolic and mean blood pressure at desired intervals (once for every 1-10 min) using the volume-oscillometric technique. Systolic and mean blood pressures obtained by the volume-oscillometric method were well correlated with those by a direct (Oxford) method (r=0.89 and 0.88, respectively) and with those by conventional arm-cuff method (r=0.90 and 0.87, respectively). Compared with conventional fully automatic portable devices with arm-cuff, this device is lighter and less noisy, and finger-cuff inflation causes less discomfort. With the present device the measurement can be conducted on the patient repeatedly without any discomfort or stress and without disturbing sleep. This device easily detected a rapid change in blood pressure in patients with pheochromocytoma or orthostatic hypotension, a cir-cadian rhythm of blood pressure in hypertensive patients, and a degree and duration of the effect of antihyper-tensive drugs. This fully automatic device for measuring ambulatory blood pressure based on the volume-oscil-lometric method gives reliable 24-hour ambulatory blood pressure and is quite useful for diagnostic, epi-demiologic, physiologic and clinical pharmacologic studies of hypertension.
