Produce first most clear signal - reflect SBP
Oscillation amplitude reaches the peak - reflect MAP
When the cuff pressure is suddenly lowered - reflect DBP
Measuring mode: manual mode and automatic mode. Each mode shows systolic, mean and diastolic
blood pressure.
Manual mode
Using Manual mode start to measures by hand
Automatic mode measures
Use manual mode to open automatic mode, then the measure will automatically turn to
automatic mode after a certain time. During measurement, any error will stop the current
automatic measurement, but not affect next automatic measurement unless the time interval
less than 30s. If the time interval less than 30s, should delay the next automatic measurement,
keep the interval more than 30s.
The time interval can be choose In Automatic mode as 1, 2, 3, 4, 5, 10, 15, 30, 60, 90, 120, 180,
240, 480 minutes.
The monitor is defibrillation proof, so the monitor operates normally after defibrillation.
6.2 Safety information
WARNING
Do not carry out non-invasive blood pressure measurement on patients with sickle cell
disease and skin damage or any expected damage. Do not measure NIBP on traumatic
body part. This may cause further injury.
When pediatric and neonate patients are measured, in order to ensure the cuff pressure
does not exceed its maximum measurement range of patient types (Adult mode:
300mmHg and Pediatric mode: 240mmHg, Neonate mode: 150mmHg), you must ensure
that you have selected the correct patient type (see patient information menu settings).
Using the wrong type of pattern is likely to endanger the patient to patient safety, as
higher blood pressure levels for adults does not apply to pediatric and neonate.
For patients with severe coagulation disorder, determine if the automatic blood pressure
measurement is carried out according to the clinical evaluation, since the friction of body
and cuff may produce hematoma.
Do not install a cuff on the limbs with intravenous infusion or duct, because it may lead
to tissue damage around the duct when the cuff is inflated and makes the infusion slow
down or be blocked.
The inflatable tube connecting the blood pressure cuff and the monitor should be
smooth without entanglement. The pressure generated by being kinked connection
tubing may cause blood flow interference.
For patients with severe thrombotic disorders, determine whether to carry out
automatic blood pressure measurement according to the clinical situations, since the
limb bundled with a cuff may produce hematoma.
Measure blood pressure frequently will affect the distribution of blood flow, May
endanger the safety of patients.
Check the patient's physiological condition before measure blood pressure, in order to
ensure that long time measure will not damage the circulation of patients
For mastectomy patients, applying the NIBP cuff on the surgery side arm can cause
lymphedema. Measure blood pressure on opposite side arm.
Pressurization of the cuff can temporarily cause loss of function of simultaneously used
monitoring device on the same limb.
Measurement results may be affected by posture and mental state of the patient.
If there are doubts on the measurement results, please use other blood pressure
measurements and compare, if necessary, contact the Equipment Division.
