Effect: Could lead to an inaccurate reading.
Fix: Check both arms initially, and in the future, use the arm with the higher result.
Note: If there’s a difference of more than 10 points, see a doctor—it might signal vascular issues.
4. Crossing Legs or Poor Foot Support
Effect: Might raise pressure by as much as 15 points.
Fix: Sit with your feet flat on the floor and avoid crossing your legs.
5. Incorrect Arm Position
Effect: If the arm is too low, the reading may be up to 7 points too high; too high, and it may read lower than it actually is.
Fix: Keep your arm at heart level.
Tip: Use a cushion or firm armrest to maintain the right position.
6. Unsupported Back
Effect: Could lead to an increase of up to 11 points.
Fix: Sit on a chair that supports your back properly.
7. Using the Wrong Cuff Size
Effect: A cuff that’s too small for a large arm can exaggerate readings; too large on a small arm can underestimate them.
Fix: Use a cuff that matches your arm’s circumference.
Tip: Check the fit by measuring your arm and comparing it to the cuff’s range.
