Preparation before use
• When the cuff is secure,
check it is not too loose or
too tight. You should be
able to place two/three
fingers between the cuff
and arm.
• If the cuff is wrapped
tightly or loosely,
inaccurate blood pressure
readings may result.
• If you are wearing a
shirt that might restrict
circulation in your upper
arm, roll your sleeve up over
the upper arm to ensure an
accurate measurement.
