为什么袖带尺寸对于血压计很重要？
The cuff size in a blood pressure monitor is crucial because a cuff that is the wrong size can give inaccurate readings. A cuff that's too tight could result in a reading that's too high, while a cuff that's too loose could result in a reading that's too low. The cuff should encircle at least 80% of the arm for an accurate reading.
血压计中的袖带尺寸至关重要，因为尺寸错误的袖带可能会给出不准确的读数。袖带太紧可能导致读数太高，而袖带太松可能导致读数太低。袖带应至少环绕手臂 80%，以确保读数准确。
