Features: - User friendly - Latex free - Long hose How to use the Cuff efficiently: - Wrap the cuff around the patient's arm and use the INDEX line to make out if the patient's arm circumference is within the targeted area. - Wrap the BP cuff snugly around the arm. - Right on the same arm that you place the BP cuff, examine the arm at the crease to locate the strongest pulse sound and place the bell of the stethoscope over the brachial artery at this location. - Inflate the BP Cuff by pumping the cuff bulb as you listen to the pulse sound. Just when the BP cuff has inflated enough to stop the blood flow, you should hear no sound through stethoscope. The gauge should read 30-40 mmHg above a person's normal BP reading. - Gradually deflate the BP cuff by losing the hold on the bulb. It is best learnt that the pressure should fall at 2-3 mmHg per second, anything faster than that may tend to provide a false reading.
