A&D UA Series Wide Range Cuff For Use With Digital Blood Pressure Monitors A wide range adult latex free cuff for A&D UA series automatic upper arm blood pressure monitors. This cuff fits an arm from 22-42 cm in diameter and includes the connector. It can be used as an alternative to the standard adult (22-32cm) or large adult (31-45cm). Using the correct size cuff is important for an accurate reading. A cuff that is too large will produce a reading that is lower than the correct blood pressure. A cuff that is too small gives a measurement that is higher. To ensure you have the correct cuff size measure the circumference of your upper arm at the bicep midway between the shoulder and elbow. Comfortable, easy to use cuff. Genuine A & D product. Large 22-42cm upper arm (bicep). MPN: AND-CUFF-WIDE
