3. Proper cuff selection and application is essential in ensuring the accuracy of blood pressure
measurements. To select the proper cuff, first measure the circumference of the limb at the point
where the cuff is to be applied. Match the limb measurement to the range of appropriate
circumferences (in centimeters) specified on each cuff (refer to the table below).
4. Position the cuff so that the center of the inflatable bladder is directly over the brachial artery. The
center of the bladder location is marked on the outside of the cuff. Once the proper position is
determined, the cuff must be tightened to ensure that it is equally snug at the top and bottom
edges and that it is not kinked. This is especially important on larger arms. Insert a finger
between the cuff and the limb to ensure it is not too tight. It may be necessary to wrap the cuff
with its tail at an angle to achieve uniform tightness. If the cuff is not equally snug at the top and
bottom edges, the number of readings available will be limited and the monitor may indicate that
the cuff is improperly applied.
• Use only Spacelabs Medical cuffs with this monitor. Using other manufacturer's
!
cuffs may result in inaccurate readings even if the manufacturer's recommended
size is observed.
• If the cuff is too small, pressure readings may be falsely high; a cuff that is too
large produces a falsely low reading. The bladder can be positioned in the cuff for
either the left or right arm.
CAUTION:
• Avoid compression or restriction of pressure in the NIBP patient connector
tubes. Check that operation of the equipment does not result in prolonged
impairment of circulation.
• Do not apply cuff to areas of breached or injured skin.
• Cuff hose connections use luer fittings. Be careful not to connect the ABP
monitor into an intravenous fluid line when working close to them.
• This product contains natural latex rubber components to which some
people may be allergic. These components include the bladder and the first
four inches of tubing extending from the cuff.
5. Once cuff is applied, the arm should be relaxed at the patient's side. To avoid reading errors due
to hydrostatic pressure differences, the level of the cuff on the arm should be near the level of
the heart.
