HOW UB-328 WORKS
?
BEFORE YOU START
LifeSource™
Blood Pressure Monitors are easy to use, accurate
and display clear digital measurements. Our technology is based
on the “oscillometric method”. The term “oscillation” refers to the
measure of vibrations caused by the arterial pulse, and is a non-
invasive method to determine blood pressure.
Our monitors examine the pulsatile pressure generated by the
arterial wall as it expands and contracts with each heartbeat
against the monitor’s cuff. The cuff inflates until the artery is fully
blocked at which point the monitor takes a measurement as the
cuff deflates.
The UB-328 provides accurate readings on wrists with a circumfer-
ence between 5.3" and 7.7" (13.5 cm and 19.5 cm).
The unit requires two “AAA” (1.5 volt) batteries to operate. To
install batteries (or to replace when “Low Battery” symbol
appears), proceed as follows:
1.
Slide the battery cover as shown to remove
from the device.
2.
Insert batteries into designated areas
ensuring a correct match with positive (+)
and negative (-) terminals.
3.
Return battery cover by sliding back on to
monitoring device.
Tips for Blood Pressure Monitoring:
☞
Relax for 5 to 10 minutes prior to measurement
☞
Remove watch, jewelry or tight-fitting garments
☞
Use left wrist unless otherwise recommended by physician
Now you are ready to follow these simple steps:
1
.
Sit comfortably in a chair near a flat surface.
2.
With palm facing upward, attach monitor to
left wrist and fasten securely. The top edge of
the cuff should align with the crease of your
wrist.
3.
Position your wrist so it is level with your
heart, using an arm rest if needed.
Positioning of the wrist at heart level is
critical for accurate measurement.
NOTE: To stop inflation at any time, press START
4.
Press START button. All symbols will briefly appear, and the
cuff will begin to inflate. It is normal for cuff to feel very tight.
5.
Remain still and refrain from talking or moving during reading.
NOTE: If a reading is not correctly detected, the device will start
to automatically re-inflate.
