6.2. Attention for Operation
A. Please check the device before use, and confirm that it can work normally.
B.The finger should be in a proper position (see the attached illustration of Figure 5 for reference), or else it may result
in inaccurate measure.
C.The ray between luminescent tube and photoelectric receiving tube must get across subject's arteriole.
D. The Oximeter probe should not be used at a location or limb tied with arterial canal or blood pressure cuff or
receiving intravenous injection.
E. Ensure nothing, such as a plaster, can impede the light passage., or else it may result in inaccurate measure of
SpO2,pulse rate and PI.
F. Excessive ambient light may affect the measure result. It includes fluorescent lamp, dual ruby light, infrared heater,
direct sunlight and etc.
G. Exquisite action of the subject or extreme electrosurgical interference may also affect the accuracy.
H.Testee can not use enamel or other makeup.
I. Please clean and disinfect the device after operating according to the User Manual (7.1).
6.3. Clinical Restrictions
A. As the measure is taken on the basis of arteriole pulse, substantial pulsating blood flow of subject is required. For a
subject with weak pulse due to shock, low ambient/body temperature, major bleeding, or use of vascular contracting
drug, the SpO2waveform (PLETH) will decrease. In this case, the measure will be more sensitive to interference.
B. For those with a substantial amount of staining dilution drug (such as methylene blue, indigo green and acid indigo
blue), or carbon monoxide hemoglobin (COHb), or methionine (Me+Hb) or thiosalicylic hemoglobin, and some with
icterus problem, the SpO2 determination by this device may be inaccurate.
C. The drugs like dopamine, procaine, prilocaine, lidocaine and butacaine may also be a major
factor resulted in serious error of SpO2measure.
D. As the SpO2 value serves as a reference value for judgment of anemic anoxia and toxic
anoxia, some patients with serious anemia may also report good SpO2 measure.
7. MAINTAIN, TRANSPORTATION AND STORAGE
7.1. Cleaning and disinfecting
Using medical alcohol to disinfect the device, nature dry or clean it with a soft cloth.
7.2. Maintain
A. Please clean and disinfect the device before use according to the User Manual (7.1).
B. Please recharge the battery when the screen shows red aglimmer "Battery Too Low" alarm information.
C. Recharge the battery soon after the over-discharge. The device should be recharged ever six months when it is not
regular used. It can extend the battery life following this guidance.
D. The device needs to be calibrated once a year (or according to the calibrating program of hospital). It also can be
performed at the state-appointed agent or just contact us for calibration.
7.3 Transportation and Storage
A. The packed device can be transported by ordinary conveyance or according to transport
contract.The device can not be transported mixed with toxic, harmful, corrosive material.
B. The packed device should be stored in room with no corrosive gases and good ventilation.
Temperature: -40ºC-60ºC; Relative Humidity: ≤95%
