Question 5

What happens if the blood pressure cuff is too small?

Answer 5

TOO SMALL: If less than 80% of the arm is covered by the air bladder, then the cuff may not be able to COMPLETELY close off the blood vessels. In this case, the bladder will inflate too much and the monitor will give a HIGHER reading than it should.

TOO BIG: If the cuff is too large, and the air bladder in the cuff overlaps (covers more than 100% of the arm), then the cuff will inflate on itself. This means that it will cut off the blood supply too EASILY and the monitor will give a LOWER reading than it should.
