3 . OPERATION

3.1 Selecting cuff size
First select a suitably-sized cuff for the circumference of the extremity. The table
below provides information about the relevant sphere of application.
Size 1 Infant
Size 2 Young child
Size 3 Adult/small
Size 4 Adult
Size 5 Adult/large
Size 6 Thigh

3 .2 Performing a measurement

The cuff is applied so that the lower edge of the cuff is approx. 2 to 3 cm above
the elbow/approx. 5 cm above the knee joint. Note the marking for artery position
as you do this. Wind the cuff around the extremity neither too loosely nor too
tightly, and ensure that the edge of the marking is within the permitted range. Close
the valve on the air drain screw. The pressure required (approx. 30 mmHg above
expected systolic pressure) is generated in the cuff by pumping the inflation bulb just
a few times. The valve is opened slowly and blow-off speed metered to 2 to 3 mmHg
per second. Using a stethoscope, it is now possible to auscultate Korotkoff sounds.
Once measurement is complete, open the valve to vent the cuff completely.
