During upright exercise, the normal blood pressure response is to observe a progressive increase in systolic blood pressure with no change or even a slight decrease in diastolic blood pressure. The slight decrease in diastolic blood pressure is due primarily to the vasodilation of the arteries from the exercise bout.
Studies have shown that using too small of a blood pressure cuff can cause a patient's systolic blood pressure measurement to increase 10 to 40 mmHg. Blood Pressure Cuff Used Over Clothing1,3,4 - When having your blood pressure measured, the cuff should always be placed directly on your arm. Studies have shown that clothing can impact a systolic blood pressure from 10 to 50 mmHg.
