Omron M2 Blood Pressure Monitor (model HEM-7143-E) is a compact, fully automatic upper arm blood pressure monitor engineered for reliable at-home use, clinically validated for accuracy in detecting hypertension and pulse irregularities. Weighing just 0.25kg with dimensions of 103 x 140 x 82 mm, it operates on 4 AA batteries (included, lasting ~1,000 measurements) or optional AC adapter, displaying results on a clear LCD screen within seconds via oscillometric method. Core Intellisense™ technology inflates the cuff to the ideal level based on your blood pressure, avoiding overinflation discomfort, while the cuff wrap guide ensures proper positioning for precise readings (systolic 60-260 mmHg, diastolic 40-130 mmHg, pulse 40-180 bpm). Additional safeguards include irregular heartbeat detection (alerts if rhythm varies >25%), body movement error signals to prompt repositioning, and a 30-reading memory per user for tracking trends—though no averaging function or app connectivity. The pre-formed medium cuff fits arm circumferences of 22-32cm; for larger arms, consider compatible extensions. Usage: Rest 5 minutes seated with back supported, arm at heart level; wrap cuff snugly 1-2cm above elbow, press START/STOP to inflate/deflate automatically (takes ~30-45 seconds), and note results—avoid caffeine/exercise 30 minutes prior. Store in the included case at room temperature (10-40°C), away from moisture/sunlight; clean cuff with damp cloth, never submerge. Precautions: Not for children under 12 or those with arrhythmias without doctor guidance; ensure cuff fit to avoid errors (±3 mmHg accuracy); discontinue if pain/swelling occurs and seek medical help.
