Reusable Veterinary SPO2 Sensor User Manual

Intended Use & Indications for Use

The SpO2 SENSORS are intended for continuous noninvasive monitoring of functional oxygen saturation of arterial hemoglobin (SpO2) and pulse rate (PR). These compatible replacement sensors are intended for use with major pulse oximeter brands. The SpO2 sensors are designed to match the specifications of the original equipment manufacturer, therefore confirm that the appropriate sensor model numbers are being used with the correct pulse oximeter technology.

It may be used in the hospital, clinical environment, homecare, and during emergency land transportation. The SpO2 sensors works with Compatible device providing SpO2 and pulse rate on horse, rabbit、 dog and cat.

Principle of Operation

The sensors must be connected to its corresponding monitor. Blood oxygenation is measured by detecting the infrared and red light absorption characteristics of deoxygenated hemoglobin and oxygenated hemoglobin, which consists of a probe attached to the patient. The sensor is connected to a data acquisition system which is used to calculate and display oxygen saturation levels and heart rate conditions.


  • Connect the SpO2 SENSOR to the oximeter’s adapter cable (or directly into the monitor).
  • Turn the oximeter on and verify proper operation.
  • Select the sensor site on the patient. The preferred sensor sites are the tongue or anus for animal.
  • Apply the sensor to the animal.
  • Visually monitor the sensor site to ensure that over time there is no harm to the patient’s skin.


  • The sensor and its cable must be cleaned before each patient use.
  • Do not use the sensor inside or near an MRI.
  • Avoid intense light sources near the sensor.
  • For long-term use, the measurement site must be checked and changed every 2-4 hours in order to guarantee the integrity of the patient’s skin.
  • Chemicals used in some cleaning agents may cause brittleness of plastic parts. Follow cleaning instructions in this manual.
  • All user and patient accessible materials are non-toxic.
  • The pins of plug must not be in contact with the cleaning fluid, otherwise it will cause permanent damage to the SpO2 sensor.


  • Connect the sensor adapter cable to the appropriate equipment (or pulse oximeter).
  • Turn on the equipment and check correct operation by consulting the monitor’s operation instructions.
  • To ensure proper monitor operations, connect and disconnect the sensor cable from the monitor cable. The correct, safe use of the sensor and its connecting cable requires systematic checks to be carried out at least once or more per month depending on the frequency of use, as well as disinfecting the cable.
  • Do a visual check (appearance of insulators, connector contact pins, etc.).
  • Verify the mechanical integrity of the connectors.
  • Do not use and discard any sensor that appears to have any mechanical or electrical flaws.

    4. Compatibility:
      In order to ensure compatibility and claimed accuracy of the devices, the SpO2 sensor should only be used with the specified equipment for which they have been designed and labeled for use.

    5. Mechanical Integrity:
      This sensor is designed to be extremely durable. We use only the highest quality materials to ensure the sensors stand up to the demanding hospital environment. The solid connectors are fitted with flexible sleeves, minimizing the risk of the cable parting. They have no accessible metallic parts.
Cleaning & Disinfecting

Clean the sensor and its connecting cable with warm soapy water or 70% isopropyl alcohol using a soft, moistened cloth. Carefully avoid damaging the surface of the visual indicator and the detector. Allow the sensor and the cable to dry thoroughly before use. Do not use any abrasive agents or chemical product except 70% isopropyl alcohol.
Do not irradiate, autoclave, soak or immerse the sensor in any kind of solution. Keep the sensor clean and dry.
The average life expectancy of a SpO2 sensor is more than a year under the conditions of use defined in these operating instructions.

Storage and Handling

When not in use, sensors should be loosely coiled and stored at room temperature. Don’t wrap sensors around equipment cases to avoid damaging internal wires.

  11. Do not use this device in the presence of flammable anesthetics or other flammable substance in combination with air, oxygenenriched environments, or nitrous oxide.
  12. This device is intended for use by persons trained in professional health care. The operator must be thoroughly familiar with the information in this manual before using the device.
  13. Prolonged use or the patient’s condition may require changing the sensor site periodically. Change sensor site and check skin integrity, circulatory status, and correct alignment at least every 2 hours.
  14. Significant levels of dysfunctional hemoglobins, such as carboxyhemoglobin or methemoglobin, will affect the accuracy of the SpO2 measurement.
  15. Any condition that restricts blood flow, such as use of a blood pressure cuff or extremes in systemic vascular resistance, may cause an inability to determine accurate pulse rate and SpO2 readings.
  16. Significant levels of dysfunctional hemoglobins, such as carboxyhemoglobin or methemoglobin, will affect the accuracy of the SpO2 measurement.
  17. Optical cross-talk can occur when two or more sensors are placed in close proximity. It can be eliminated by covering each site with an opaque material.
  18. Tissue damage may result from overexposure to sensor light during photodynamic therapy with agents such as verteporphin, porfimer sodium, and metatetrahydroxyphenylchlorin (mTHPC).
  19. Change the sensor site at least every hour and observe for signs of tissue damage. More frequent sensor site changes/inspections may be indicated depending upon the photodynamic agent used, agent dose, skin condition, total exposure time or other factors. • Use multiple sensor sites.
  20. Under certain clinical conditions, pulse oximeters may display dashes if unable to display SpO2 and/or pulse rate values. Under these conditions, pulse oximeters may also display erroneous values. These conditions include, but are not limited to: patient motion, low perfusion, cardiac arrhythmias, high or low pulse rates or a combination of the above conditions. Failure of the clinician to recognize the effects of these conditions on pulse oximeter readings may result in patient injury.
