Measurement
16
4.2 Precautions
Note
Do not perform SpO
2
monitoring and NIBP measurements on the
same arm simultaneously. Obstruction of blood flow during NIBP
measurements may adversely affect the reading of the SpO
2
value.
It is recommended that each measurement last longer than 15
seconds. Otherwise, if the SpO
2
sensor falls off during the
measuring process, new data can’t be added to the same patient.
The Pulse Oximeter is not recommended for prolonged monitoring.
Warning
Check the SpO
2
sensor and its cable for damages before use. Do
not use damaged parts.
Don’t use the Pulse Oximeter to measure patients whose pulse
rate is lower than 25bpm, which may cause incorrect results.
Remove the SpO
2
sensor from the patient after measurement.
As with any medical equipment, carefully route patient cabling to
reduce the possibility of patient entanglement or strangulation.
Cables of electrical surgical equipment should not be winded
around that of the SpO
2
sensor.
Do not put the sensor on extremities with arterial catheter or
venous syringe.
If no pulse is found or the reading is unreasonable, first check the
patient’s condition, and then refer to qualified engineer to check the
device and the SpO
2
sensor for proper functions.
Do not reuse disposable SpO
2
sensors.
