WARNINGS!
•
If any abnormality is observed, stop the blood pressure
measurements.
•
If you suspect the accuracy of the value, please adopt other method
to further check.
•
If the liquid splashes on the device or accessories, especially liquid
enter into the device, please connect the local service center.
•
Inaccurate measurements may result from such causes:
a. Limb’s twitch and tremble will cause inaccuracy or prolonged the
cycling of measurement; serious tremble will lead to the failure of
measure.
b. Placing the cuff too loosely or tightly on the patient.
c. Leaky cuff or hose
d. Insure the NIBP and pulse rate within the range of this monitor.
e. Excessive patient motion will cause the inaccuracy, patient should be
relax and avoid movement.
f. Arrhythmia lead to irregular heart beat
g. Use the artificial heart-lung machine
h. The patient is in shock or low temperature.

Notes:
•
Ensure that the cuff is completely deflated.
•
Apply the appropriate size cuff to the patient, and make sure that
the symbol “Ф” is over the appropriate artery. Ensure that the cuff is
not wrapped too tightly around the limb. Excessive tightness may
cause discoloration and eventual ischemia of the extremities.
•
The width of the cuff should be either 40% of the limb circumference
or 2/3 of the upper arm length. The inflatable part of the cuff should
be long enough to encircle 50~80% of the limb. The wrong size of
cuff can cause erroneous readings. If the cuff size is in question,
then use a larger cuff.
•
Make sure that the cuff edge falls within the range of mark <->. If it
does not, use a larger or smaller cuff that fits better.
•
Connect the cuff to the air hose. The limb chosen for taking the
measurement should be placed at the same level as the patient’s
heart. If this is not possible you should apply the following
corrections to the measured values.
•
If the cuff is placed higher than the heart level, add 0.9 mmHg
(0.10kPa) for each inch of different.
•
If it is placed lower than the heart level, deduct 0.9 mmHg (0.10kPa)
for each inch of different.
•
The rated range of cuff pressure: 0mmhg~380mmhg.
Measuring
Press the shortcut button(NIBP) the user feel the cuff inflation. After
that, the device will automatically deflate. Finally, the screen will display
the results: Systolic Blood Pressure and Diastolic Blood Pressure. The
interface is as shown in Fig.4.5
