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 artery index marker falls short of range, a larger cuff
should be used to ensure accurate results. If the artery 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.
Inflation System Change and Replacement
The Welch Allyn DuraShock integrated blood pressure gauge connects effortlessly
to the inflation system via a unique port connection. Therefore, only Welch Allyn
integrated blood pressure cuffs can be used with the Welch Allyn DuraShock
integrated blood pressure gauge.
1. To remove the inflation system, simply grasp the gauge and
pull away from the cuff. Rotating the gauge as it is being
pulled away from the cuff will make removal easier.
2. To attach a new or different size blood pressure cuff, simply
press the gauge stem into the cuff port until you feel it
engage. Rotating the gauge as it is being pressed into the
cuff will make insertion easier.
Specifications and Standards
The Welch Allyn DuraShock integrated aneroid sphygmomanometer is accurate to
±3 mm Hg and conforms to applicable sections of the following standards for aneroid
sphygmomanometers:
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). 1/16 inch
