3. Initial Setup
3.1 Powering the Device
The ABPM50 is powered via a corded electric connection, typically through a USB cable for charging its internal battery. Connect the provided USB cable to the device and a suitable power source (e.g., a computer USB port or a USB wall adapter). Ensure the device is fully charged before initial use for optimal performance, especially for 24-hour monitoring.
3.2 Attaching the Blood Pressure Cuff
Connect the air tube from the blood pressure cuff securely to the air port on the side of the ABPM50 main unit. Ensure the connection is firm to prevent air leakage during measurement. The cuff is designed for adult, pediatric, and neonate use, with the included cuff being suitable for adults. Proper cuff placement is crucial for accurate readings. Position the cuff on the upper arm, ensuring the artery marker aligns with the brachial artery. The cuff should be snug but not overly tight, allowing two fingers to fit underneath.
