• b) Relative humidity: ≤95%
• c) Atmospheric pressure: 500hPa~1060hPa

Operating Environment

• a) Temperature: 10˚C~40˚C
  b) Relative Humidity: ≤75%
  c) Atmospheric pressure: 700hPa~1060hPa

Principle and Caution

Principle of Measurement

• The principle of the Oximeter is as follows: An experience formula of data process is established taking use of Lambert-Beer Law according to Spectrum Absorption Characteristics of Reductive Hemoglobin (Hb) and Oxyhemoglobin (HbO2) in glow & near-infrared zones. The operation principle of the instrument is: Photoelectric Oxyhemoglobin Inspection Technology is adopted in accordance with Capacity Pulse Scanning & Recording Technology so that two beams of different wavelengths of light can be focused onto a human nail tip through a perspective clamp finger-type sensor. Then measured signal can be obtained by a photosensitive element, information acquired through which will be shown on screen through treatment in electronic circuits and microprocessors.

Caution

1. The finger should be placed properly (see the attached illustration of this manual, Figure 7), or else it may cause inaccurate measurement.
2. The SpO2 sensor and photoelectric receiving tube should be arranged in a way with the subject’s arteriole in a position there between.
3. The SpO2 sensor should not be used at a location or limb tied with arterial canal or blood pressure cuff or receiving intravenous injection.
4. Make sure the optical path is free from any optical obstacles like fabric or artificial nails.
5. Excessive ambient light may affect the measuring result. This includes fluorescent lamp, dual ruby light, infrared heater, direct sunlight and etc.
6. Strenuous action of the subject or extreme electrosurgical interference may also affect the accuracy.
7. User can not use enamel or artificial nails.

Clinical Restrictions

1. 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 SpO2 waveform (PLETH) will decrease. In this case, the
   measurement will be more sensitive to interference.

2. 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 monitor may be
   inaccurate.

3. The drugs like dopamine, procaine, prilocaine, lidocaine and butacaine may also be a major factor blamed for serious error of SpO2 measure.

4. As the SpO2 value serves as a reference value for judgement of anemic anoxia and toxic anoxia, some users with serious anemia may also report good
   SpO2 measurement.

Recommended separation distance

Where P is the maximum output power rating of the transmitter in watts (W) according to the transmitter manufacturer and d is the recommended separation distance in metres (m).

Field strengths from fixed RF transmitters, as determined by an electromagnetic site survey, a should be less than the compliance level in each frequency range.b

Interference may occur in the vicinity of equipment marked with the following symbol

NOTE 1 At 80 MHz and 800 MHz, the higher frequency range applies.

NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects and people.

Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur radio, AM and FM radio broadcasts and TV broadcasts cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF

transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location in which the PO2BLU/PO2BLK is used exceeds the applicable RF compliance level above, the PO2BLU/PO2BLK should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the PO2BLU/PO2BLK .

b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
