The Omron M3 Comfort AFib is an automatic upper arm blood pressure monitor suitable for people who need to regularly monitor their blood pressure at home. Its main advantage is combining blood pressure measurement with the detection of possible heart rhythm changes, including atrial fibrillation, helping to identify signs that should be evaluated by a healthcare professional. The device uses IntelliSense technology, which automatically controls cuff inflation according to each user, providing a comfortable measurement. The 22–42 cm Intelli Wrap cuff is designed to maintain measurement accuracy in different positions around the arm and includes an indicator to help confirm it is correctly positioned. The AFib function automatically detects possible atrial fibrillation during blood pressure measurement. The device also identifies irregular heartbeats and body movements that may interfere with the measurement. AFib detection is a screening function and does not replace a medical diagnosis or an electrocardiogram. The M3 Comfort AFib also allows for three consecutive measurements and average calculation, helping to obtain a more consistent assessment of blood pressure. The memory allows for storing up to 60 measurements for each of two users, in addition to a guest mode, facilitating the monitoring of values over time. The device is clinically validated and has specific validation for diabetes, pregnancy, and pre-eclampsia, according to information provided by the manufacturer. Includes storage case, four AA batteries, and Intelli Wrap cuff.
