Purpose of Ambulatory Blood Pressure Monitoring:

Ambulatory blood pressure monitoring allows for blood pressure measurements to be taken at regular intervals over a 24-hour period while the user goes about their daily activities, including sleep. This provides a more comprehensive picture of blood pressure patterns compared to single-point measurements, aiding in the diagnosis and management of hypertension.
