3. Activate the digital aneroid and inflate the cuff:
Press the “ ” On/Off
button to activate your digital gauge. After zeroing, your digital gauge is ready to
measure. Close the ADFLOW
TM
valve by turning thumbscrew clockwise.
Palpate the radial artery while inflating the cuff. Be sure to inflate cuff quickly
by squeezing bulb rapidly. Inflate cuff 20-30 mmHg above the point at which the
radial pulse disappears.
4. Position the Stethoscope:
Position the chestpiece in the antecubital space
below the cuff, distal to the brachium. Do not place chestpiece underneath the
cuff, as this impedes accurate measurement. Use the bell side of a combination
stethoscope for clearest detection of the low pitched Korotkoff (pulse) sounds.
5. Systolic Assist Function and Pulse:
Your digital e-sphyg
TM
gauge is equipped
with a systolic assist function to help you more easily determine the onset of
systolic blood pressure. As you deflate the cuff, a heart symbol will flash when
the pressure is within about 20 mmHg of systolic pressure. Once you
see the flashing symbol, pay close attention for the start of phase 1 Korotkoff
sounds. The digital gauge will also measure the patient’s pulse while you are
measuring blood pressure, and display this information on the LCD screen
once the cuff has been deflated.
6. Deflate the cuff:
Open the valve to deflate the cuff gradually at a rate of
2-5 mmHg per second (2-3 is preferred). The display will show the average
deflation rate in the lower right corner of the LCD screen.
7. Measurement:
Record the onset of Korotkoff sounds as the systolic pressure,
and the disappearance of these sounds as diastolic pressure. (Some healthcare
professionals recommend recording diastolic 1 and diastolic 2. Diastolic 1
occurs at phase 4).
After measurement is completed, open valve fully to release any remaining air
in the cuff. The digital gauge will now display the patient’s pulse. Remove cuff.
BACKLIGHT CONTROL
The default setting on your digital gauge is to have the back light on once the
pressure is inflated over 30 mmHg, and throughout the measurement process.
To switch the backlight off at any time, press the “ ” button on the left side.
You will need to deactivate the backlight each time you power on the instrument.
CARE AND MAINTENANCE
Storage:
After measurement, wrap cuff around gauge and bulb and store in zippered
carrying case.
Cleaning: Digital Manometer
: Your ADC
®
DIAGNOSTIX
TM
brand e-sphyg
TM
gauge
requires minimal care and maintenance.
The manometer may be cleaned with a slightly dampened soft cloth, but should not
be dismantled under any circumstances.
Cuff:
Sponge with a damp cloth or alcohol pad. If necessary, it can be washed in
cool water with mild soap or detergent-disinfectant. Remember to remove bladder
from cuff prior to washing. After washing, it should be rinsed and allowed to air dry.
NEVER IRON.
Be sure to remove the bladder and all components before cleaning
the cuff.
Bladder and Bulb:
Remove bladder from cuff and disconnect bulb from tubing and
valves. Wipe with a damp cloth. To help preserve it from cracking or discoloring,
wipe with a soft cloth moistened with ethanol.
Valves:
Clean the surface with a dry fabric such as soft cotton material. Remove
dust from filter screen.
Carry Case:
Wipe with a damp cloth and dry thoroughly with a dry cloth. If
necessary, it can be washed with cool water and mild soap. Do not allow to air dry.
Batteries:
If the e-sphyg
TM
will not be used for an extended period of time, remove
batteries.
DISINFECTION AND STERILIZATION
Disinfecting:
Glutaraldehyde-type liquid disinfectant may only be used on the cuff.
Follow instructions for use provided with the glutaraldehyde product. Prolonged use
of this disinfectant may cause discoloration. DO NOT use glutaraldehyde-type liquid
disinfectant on the digital gauge, bulb, valves, or bladder.
Sterilizing:
The blood pressure cuff may be gas sterilized.
DO NOT
use steam or
heat to sterilize the cuff, bulb, valve, or bladder.
DO NOT
attempt to sterilize the
digital gauge.
