The practice of ambulatory blood pressure (ABP) monitoring encompasses the regular assessment of blood pressure (BP) at consistent intervals, often occurring every 20 to 30 minutes, throughout a 24-hour span. This monitoring takes place as individuals engage in their typical daily tasks, including sleep. A portable monitoring device, secured to a belt, features a standard cuff on the upper arm. It utilizes an oscillometric method to identify systolic, diastolic, and mean BP, along with heart rate. Once the monitoring is concluded, the device is connected to a computer, which generates a comprehensive report detailing average systolic and diastolic BP as well as heart rate for the 24-hour period, both during the day and night, and, if applicable, during sleep and wakefulness.
