Sphygmomanometers arm type is better than wrist type. Arm sphygmomanometers, are sphygmomanometers that measure blood pressure in the arteries of the upper arm by applying pressure through a cartridge cuff, while wrist sphygmomanometers, are sphygmomanometers that measure blood pressure in the wrist area by applying pressure through a wrist band cuff. From the clinical research evidence, the upper arm type electronic sphygmomanometer, measurement accuracy and repeatability, the effect is higher than the wrist type electronic sphygmomanometer, is the home measurement of the preferred recommendation, while the wrist type electronic sphygmomanometer, mainly for the inconvenience of exposure of the upper arm measurement and design. For patients with severe vascular sclerosis, vascular calcification, diabetes mellitus, hyperlipidemia, hypertension, and other blood disorders and vascular pathologies, the difference in blood pressure measurements between the wrist and the upper arm is usually very large, and the use of wrist-type electronic sphygmomanometers is not recommended. It is recommended that patients with cardiovascular disease or family history adhere to regular blood pressure measurements, and that those with abnormal blood pressure seek prompt medical attention and treatment as prescribed.
