Warning:
Remove batteries when the unit is not in use for extended periods of
time. Batteries are hazardous waste; please dispose of them properly.
ASSEMBLING YOUR SPHYGMOMANOMETER
Your inflation system is pre-assembled and ready for use. You will need to simply
connect your digital gauge to the complete inflation system by inserting the twist
lock connector (pre-assembled on a bladder tube) into the air port at the bottom of
the digital gauge.
If you will be hanging the gauge from the cuff gauge holder, it is recommended that
the bladder tubing connecting the gauge be trimmed to a length of 6” to 9” for con-
venience. (Note: Be sure to retain the twist lock connector needed to attach the digi-
tal gauge to the tubing.)
MEASUREMENT PROCEDURE
(Auscultatory Method)
1. Patient Position
: The patient should sit or lie comfortably. The arm should be
fully supported on a flat surface at heart level. (If the arm’s position varies, or
is not level with the heart, measurement values obtained will not be consistent
with the patient’s true blood pressure.)
2. Apply the cuff:
To attach the digital gauge, plug the connector into the gauge
and twist clockwise to ensure a secure connection. The e-sphyg
TM
gauge can be
either clipped on the gauge hang tab, or held in your hand during use.
ADCUFF
TM
nylon cuffs are specially designed to promote the accurate
determination of blood pressure. Index and range markings ensure use of the
correct cuff size. The artery mark indicates proper cuff positioning.
Place the cuff over the bare upper arm with the artery mark positioned directly
over the brachial artery. The bottom edge of the cuff should be positioned
approximately one inch above the antecubital fold. Wrap the end of the cuff
not containing the bladder around the arm snugly and smoothly and engage
adhesive strips. To verify a correct fit, check that the Index Line falls between
the two Range Lines.
CALIBRATION OF THE DIGITAL GAUGE
Gauge accuracy can be checked visually whenever it is switched on. If the unit is
used more than 10,000 times, a calibration reminder message (CAL) will appear on
the digital display. Any digital gauge that displays this message should be returned
for re-calibration to ADC’s Service Department. Only ADC or an authorized service
technician is qualified to perform this calibration service.
Do not attempt to recalibrate the gauge yourself.
In addition to the visual inspection indicated above, we also recommend you
perform the following calibration check on an annual basis:
• Connect your gauge to a high-quality, known pressure standard using ADC’s
“Y” Test Kit (part number 991)
• Pressurize the gauge to 300 mmHg
• Reduce the pressure at a rate no greater than 10 mmHg per second, and stop
to check at the following test points: 300mmHg, 240 mmHg, 160 mmHg,
120 mmHg, and 80 mmHg. Your gauge should be /-3 mmHg of your
reference standard.
ADC recommends using the most sensitive pressure standard possible when
performing this calibration check, as your ability to measure the accuracy of a gauge
depends on the sensitivity of the pressure standard. If you are using a reference
pressure standard that is only calibrated to +/- 3 mmHg (such as a mercury column
or aneroid gauge), then you will only be able to determine the accuracy of the test
gauge to /- 6 mmHg. If you use a reference pressure standard that is +/- .01
mmHg (such as a digital pressure standard), you will be able to determine the
accuracy of the gauge being tested to /- 3.1 mmHg.
In the event that the gauge is ever in need of calibration, simply return to ADC.
Damaged or broken parts will be replaced as needed at a minimum charge. Refer to
the warranty for specific details of warranty coverage.
