Health assessment: What is the effect of too tight or too loose sleeves on blood pressure when measuring blood pressure?

Hello, when measuring blood pressure, the sleeve is too tight or too loose, which will definitely have a certain impact on blood pressure. Generally speaking, the blood pressure measured by the same patient when the cuff is tight will be slightly higher than that when the cuff is loose, but the difference will not be too great, generally not exceeding 15 nHg. Therefore, patients are advised to consider the situation comprehensively.
