What is the maximum speed at which BP cuff can be deflated while measuring blood pressure?

Maximum speed at which BP cuff can be deflated while measuring blood pressure is 3 mm Hg/second. If the cuff is rapidly deflated, the blood pressure measurement error will be high. Initial inflation of cuff should be rapid and about 30 mm Hg above the anticipated blood pressure. Cuff should be deflated fully after measuring diastolic pressure for at least one minute before a repeat measurement is attempted.
