Notice items:

  1.  pulse oximeter probe placement, the position without ductus arteriosus, BP cuff and vein input pipe is top-priority.
  2. If the pulse oximeter probe can’t monitor the state of pulsation, it shows that the position of probe is improper, or the position is too thick, too thin or having too deep pigment to reach a proper translucidus effect. If above things has happened, place the probe again or select probe of other type.
  3. This pulse oximeter probe should be applied to the special medical equipment. Operator is responsible to check the compatibilityn Incompatible fittings or device will influence the measuring result.

Environment requirements

Transport and storage

  1. Temperature: -10℃~+40℃
  2. Humidity: less than 80%
  3.  Pressure:500hPa~1060hPa


  1. Temperature: 10℃~+40℃
  2. Humidity: 30% ~ 75%
  3. Pressure: 700hPa~1060hPa


  1. pulse oximeter probe needs special precautions regarding EMC and needs to be installed and put into service according to the EMC information provided in User Manual and test report.
  2. Portable and mobile RF communications equipment can affect pulse oximeter probe


  1. The use of cables other than those specified, with the exception of cables sold by CONTEC as replacement parts for internal components, may result in increased emissions or decreased immunity of pulse oximeter probe.
  2. pulse oximeter probe should not be used adjacent to or stacked with other equipment and that if adjacent or stacked use is necessary, the pulse oximeter probe should be observed to verify normal operation in the configuration in which it will be used.
  3. Improper usage can result in inaccurate measurement.
  4. Using it under too strong light will cause inaccurate measurement, in case of that, please set a opaque stuff around the probe to cut light off.
  5. You should move the probe to other position per 4 hours at least. Because the state of local skin can influence the ability of skin to enduring probe, it is necessary to replace the position of probe according to the state of patient. Please do that when skin integrity
  6. The dyestuff in blood vessel cab cause the inaccurate measurement.
  7. The performance of pulse oximeter probe is influenced by movement easily, so it is not suitable for active patient to use it.
  8. Don’t fix the probe with belt or bundle it tightly, because the vein pulsation can cause inaccurate SpO2 measurement.
  9. Same as other medical equipment, the cable should be set properly to avoid enlacing or asphyxiate patient.
  10. Don’t use it in the process of MRI scan, because the conductor current may burn the skin of patient, moreover, the probe will influence MRI image and MRI set will also influence the accuracy of SpO2 measurement.
  11. Don’t change the product at will, otherwise the capability or accuracy of product will be influenced.
  12. The probe is not intended for use during patient transport outside the healthcare facility.
  13. DO NOT use the probe while the patient is being scanned by MRI or CT.

location in which the pulse oximeter probe is used exceeds the applicable RF compliance level above, the pulse oximeter probe should be observed to verify normal

operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the pulse oximeter probe.
