inaccurate.
3. The drugs like dopamine, procaine, prilocaine, lidocaine and butacaine may
also be a major factor blamed for serious error of SpO
4. As the SpO
value serves as a reference value for judgement of anemic anoxia
2
and toxic anoxia, some patients with serious anemia may also report good
SpO
measurement.

4. Technical Specifications
A. Display Format: LCD Display
SpO2 Measuring range: 0 ~100 %
Pulse Measuring range: 30bpm ~250bpm
Perfusion Index Measuring Range: 0% ~ 20%
Pulse Wave Display: columniation display and the waveform display
B. Power Requirements: 2 ×1.5V AAA alkaline battery (or using the rechargeable
battery instead), adaptable range: 2.6V~3.6V.
C. Power Consumption: Smaller than 30mA
D. Resolution: SpO
E. Measurement Accuracy: ±2% in stage of 70%-100% SpO2, and meaningless
when stage being smaller than 70%. ± 2 bpm during the pulse rate range of 30-
99 bpm and ± 2% during the pulse rate range of 100~250 bpm
F. Measurement Performance in Weak Filling Condition: SpO2 and pulse rate
can be shown correctly when pulse-filling ratio is 0.4%. SpO2 error is ±4%,
pulse rate error is ±2 bpm or ±2% (select larger).
G. Resistance to surrounding light: The deviation between the value measured in
the condition of man-made light or indoor natural light and that of darkroom
is less than ±1%.
H. It is equipped with a function switch. The Oximeter can be powered off in
case no finger is the Oximeter within 5 seconds.
I. Optical Sensor
Red light (wavelength is 660nm, 6.65mW)
Infrared (wavelength is 880nm,6.75mW)
5. Accessories
Hanging rope, pouch, silicone protector, user manual
