What is wrong with a cuff?

Incorrect Cuff Height. Cuff height is the level of the cuff compared to mid-heart level. To avoid a false blood pressure reading, the cuff must be at the same height as your heart. If the cuff is above heart level, the reading will be false and lower than your actual pressure. If the cuff is below heart level, the reading will be false …

How far away should a blood pressure cuff be from the arm?

Having the correct cuff size and tightness as indicted above is not a guarantee you still won’t get a false reading. The positioning of the cuff on the arm is just as important. There are 2 things to consider with cuff location. The 1st one is how far away the edge of the cuff should be from the bend of the arm. There is no one right answer for this distance.
