You can't beat having the reassurance of a medically certified blood pressure monitor to hand,the ability to check your reading whenever you feel things may not be quite right is invaluable to managing your health. The Beurer BM54 Blood Pressure Monitor is easy to use and easy to understand,the XL display screen shows you your reading in large digits along with the date and time. It then indicates how your reading sits on the World Health Organisation (WHO) Risk Indicator,measuring you on a simple colour-coded scale. The BM54 also has the ability to detect arrhythmia,alerting you to any irregularity in your heartbeat. While the BM54 blood pressure monitor offers two user profiles,each with a capacity to hold up to 60 readings,it also gives you the ability to transfer all your data wirelessly via Bluetooth to your PC or to the free Beurer HealthManager app on your smartphone,this is a great way to monitor your health and share your results with your health professional. The universal upper arm cuff fits a broad circumference of 22-44 cm and inflates and deflates automatically,if the cuff is placed incorrectly or your arm is held in the wrong position,the blood pressure monitor will alert you of incorrect usage,so you can be confident that each reading is an accurate one.
