DuraShock is the first and only gear-free, shock-resistant aneroid
sphygmomanometer technology. We expect you will receive years of trouble free
operation from this product.

Components of the Welch Allyn DuraShock Integrated
Aneroid Sphygmomanometer

Gear-free Gauge

Snaps into Cuff

Valve

Integrated One­Piece Cuff

Tubing

Assembly Instructions

1. Attach the gauge to the cuff by pressing the gauge
stem into the cuff port until you feel it engage. The
gauge can be rotated 360° in the cuff port to improve
your view of the dial face during readings.

2. Push the remaining smaller-diameter barb of the valve
onto the tube.

NOTE: To assemble the bumper to a Welch Allyn
DuraShock integrated gauge (model DS44 only), gently slide
bumper over the gauge until the bumper just contacts the
crystal around the entire circumference. Do not force to the
point where the bumper shape is deformed, as this will
reduce the shock-resistant properties of the bumper.
Properly assembled, about 1/16-inch (2 mm) of the gauge
will be visible below the bumper when viewed from the
side (see illustration).

Operating Instructions

Auscultatory Method

1. Select cuff size appropriate for the patient’s arm circumference. The applicable
range, in centimeters, is printed on each cuff.

Note: The “Artery Index Marker” on the cuff should fall within the
“Range” indicated on the cuff. If the index marker falls short of range,
a larger cuff should be used to ensure accurate results. If the index
marker is past the range, a smaller cuff should be used to ensure
accurate results.

2. Wrap the cuff around the arm with the artery index marker located over the
brachial artery and with the lower edge of the cuff 1-inch (2.5 cm) above the bend
in the elbow.

3. Inflate cuff rapidly to a level 30 mm Hg above estimated (or palpatory) systolic
pressure.

4. Partially open the valve to allow deflation at a rate of 2 to 3 mm Hg per second.

5. As the pressure falls, note systolic pressure and diastolic pressure with your
stethoscope.

6. Rapidly release the remaining pressure and record measurements immediately.
After a minimum of 30 seconds, repeat the above steps for a second reading.

CAUTION: Do not allow a blood pressure cuff to remain on
patient for more than 10 minutes when inflated above 10 mm
Hg. This may cause patient distress, disturb blood circulation,
and contribute to the injury of peripheral nerves.

WARNING: If luer lock connectors are used in the construction
of tubing, there is a possibility that they might be inadvertently
connected to intravascular fluid systems, allowing air to be
pumped into a blood vessel.
