Yep. I go with just semi-snug and not tight. When I do tight the reading I get is a good ten points higher systolic. Super tight it usually generates an error. Too loose and it generates an error.
Step 4: Put on the Cuff
Wrap the cuff around your arm so it’s snug but not too tight. As a rule of thumb, you should be able to slip one finger under the cuff. Place the cuff against your skin, not over your clothing. Lloyd notes not to just push your sleeve up to the top of your arm — doing so forms a tight bend around the upper arm. The bottom of the cuff should be about one inch above the bend, or crease, in your elbow. Look for an arrow or line on the cuff that should be lined up with (or point to) the pulse from your brachial artery.
