Patient Monitor User Manual Monitoring NIBP
- 127 -
WARNING
9 Measuring of blood pressure can temporarily cause malfunctioning of other medical
monitoring devices on the same limb.
10 NIBP readings can be affected by the measurement site, the position of the patient,
exercise, or the patient's physiologic conditions.
11 Continuous cuff pressure due to connection tubing kinking can block the blood flow,
and may result in injury to the patient.
12 Verifying the calibration is only applicable for adults, and it can not be operated in
automatic measuring interval. Continuous measuring can not be operated in
automatic measuring interval either.
NOTE:
1 It is suggested that the user should not start NIBP measuring when the low battery
displays, or the monitor may be turned off automatically.
2 Please confirm the result by referring to patients’ condition if the measurement fails or
if the measurements are questionable.
3 Once the measurement limits are exceeded or patients’ condition deteriorates, you
may check if the tube is twisted or is blocked.
4 If you spill liquid onto the equipment or accessories, particularly if there is a chance
that it can get inside the tubing or the measurement device, contact your service
personnel.
5 Continuous use of the automatic measuring mode for short intervals may lead to the
discomfort of patient. Continuous measuring and automatic measuring in neonatal or
pediatric mode may result in tissue damage or ischemia to the patient.
6 NIBP measurement can be affected by extremes of temperature, humidity and
altitude.
7 NIBP measurement value should be explained by qualified professionals.
8 The pulse rate based on the NIBP measurement may differ from the heart rate based
on the ECG waveform. NIBP measures the number of peripheral pulse pulsations,
and the heart rate is measured by the electrical signal of the heart. When the
electrical signals of the heart occasionally fail to cause the peripheral blood vessels
to pulse or the patient's peripheral perfusion is poor, the difference happens.
15.3 Measurement Limitations
Measurements are impossible with pulse rate extremes of less than 40 bpm or greater than 240
bpm, or if the patient is on a heart-lung machine.
The measurement may be inaccurate or impossible in the following situations:
A regular arterial pressure pulse is hard to detect.
Patients with cardiac arrhythmias.
Patients with excessive and continuous movement such as shivering or convulsions.
