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 articial heart-lung machine
h. The patient is in shock or low temperature.
Fig. 4.4
Notes:
• Ensure that the cuff is completely deated.
• 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 inatable 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 ts 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.

4.3 SpO2, PR and PI
What is SpO2Monitoring?
SpO2plethysmogram measurement is employed to determine the
oxygen saturation of hemoglobin in the arterial blood. If, for example,
97% hemoglobin molecules in the red blood cells of the arterial blood
combine with oxygen, then the blood has a SpO2oxygen saturation of
97%. The SpO2 numeric on the monitor will read 97%. The SpO2numeric
shows the percentage of hemoglobin molecules which have combined
with oxygen molecules to form oxyhemoglobin. The SpO2/PLETH
parameter can also provide a pulse rate signal and a plethysmogram
wave.
SpO2Setting
In the main screen, rotate the konb on the SpO2, press the knob enter
into the SpO2 setting screen.
You can set the high & low limit and the unit of the SpO2.

Pressure Safety Protection
• Automatic deation will be activated when the cuff pressure exceed
280 mmHg under the adult mode.
• Automatic deation will be activated when the continuous ination
last more than 30 seconds.
• If there is no value when measurement time exceeds 120 seconds
under the adult mode, the measurement will be canceled.
• You can press the START (NIBP) button to cancel a NIBP
measurement when necessary.
Maintenance and Cleaning
WARNINGS!
• Do not squeeze the hose of cuff.
• Do not allow liquid to enter the connector socket when cleaning
