More Information

  • Operation Instructions:
    - Install two AAA batteries into battery cassette before covering its cover
    - Open the clamp as illustrated in the picture below
    - Insert one finger into the rubber hole of the Oximeter (it is best to insert the finger thoroughly) before releasing the clamp
    - Press the switch button once on the front panel
    - Do not move fingers while using the Oximeter
    - Read the data from the display screen
    - Display modes
  • Precautions for use:
    - Before use, carefully read the manual
    - The operation of Pulse Oximeter may be affected by the use of an electrosurgical unit (ESU)
    - To ensure the Pulse Oximeter is able to obtain an accurate SpO2 measurement, verify nothing is interfering with the pulse measurement before recording the SpO2 result
    - Do not use the Pulse Oximeter in an MRI or CT environment
    - Do not use the Pulse Oximeter in situations where alarms are required. The device has no alarms
    - Explosion hazard: Do not use the Pulse Oximeter in an explosive atmosphere.
    - The Pulse Oximeter is intended only as an adjunct in patient assessment. It must be used in conjunction with other methods of assessing clinical signs and symptoms
    - Check the Pulse Oximeter Sensor application site frequently to determine the positioning of the sensor and circulation and skin sensitivity of the patient
    - Do not stretch the adhesive tape while applying the Pulse Oximeter Sensor. This may cause inaccurate readings or skin blisters
    - The Pulse Oximeter has no SpO2 alarms, it is not for continuous monitoring, as indicated by the symbol
    - Prolonged use or the patients condition may require changing the sensor site periodically. Change sensor site and check skin integrity, circulatory status, and correct alignment at least every 4 hours
  • Inaccurate measurements may be caused by:
    - Sterilization efforts. The device is not intended for sterilization . Use of an autoclave, ethylene oxide immersion or immersion in any liquid may cause inaccurate readings
    - Significant levels of dysfunctional hemoglobins (such as carboxyhemoglobin or methemoglobin)
    - Intravascular dyes such as indocyanine green or methylene blue
    - Use in high ambient light. SpO2 measurements may be adversely affected in the presence of high ambient light. When in use, the sensor should be shielded if exposed to direct sunlight or intense lighting
    - Excessive patient movement
    - High-frequency electrosurgical interference and defibrillators
    - Venous pulsations
    - The placement of a sensor on an extremity with a blood pressure cuff, arterial catheter, or intravascular line
    - Patient conditions of hypotension, severe vasoconstriction, severe anemia, or hypothermia
    - Cardiac arrest or shock
    - Fingernail polish or false fingernails
  • Hanging Lace Installations:
    - Thread thinner end of the hanging lace through the hanging hole
    - Thread thicker end of the lace through the threaded end before pulling it tightly
  • Maintenance and Storage:
    - Replace the batteries when the low battery voltage indicator is lighted
    - Clean surface of the fingertip on the Oximeter before each use
    - Remove the batteries if the Oximeter will not be operated for a long period of time
    - It is best to preserve the product in a place where ambient temperatures are between 10 to 40oC or 14 to 104% and humidity is between10% to 80%. It is recommended that the product should be kept in a dry environment at all times. Moisture could affect the product life and might damage the product
    - Follow local ordinances and recycling instructions regarding disposal or recycling of the device and device components, including batteries
  • Cleaning the Pulse Oximeter:
    - Clean the rubber touching the finger inside of the Oximeter with a soft dampened cloth with 70% isopropyl alcohol, and clean the test finger using alcohol before and after each test. Do not pour or spray any liquids onto the Oximeter, and do not allow any liquids to enter any openings in the device. Allow the Oximeter to dry thoroughly before reusing
