(For stable measurements, adjust the measuring point of the finger holder or rub or warm the measuring point to improve blood circulation, so that the pulse level  enter constantly indicates level 2 or higher.)

Calculation method for displayed valuesOxygen saturation value (SpO2 ):The value obtained by performing moving average for the last 5 seconds is updated and displayed every second.Pulse rate (P.R.):The value obtained by performing moving average for the last 8 pulse rates is updated and displayed every second.

Back LightThe backlight will light up automatically when the surroundings become dark.When the backlight isn’t turned by the bright surroundings, cover the backlight sensor window with finger.

  • Once the backlight is lit, it will remain lit until measurement stops.
  • When the battery mark is blinking, the backlight isn’t turned on. Please replace the battery.

Error Messages

■ Messages relating to the connection of the finger holder and attachment to the patient

Error Messages Cause Solution
• Insufficient light for measurement.• Strong light enters the finger holder’s sensor directory. • Check that the finger holder is properly attached to the patient.• Clean the light source and sensor sections.• Take measures to prevent direct entry of strong light to the finger holder.
• Pulse signal required for measurement is not being received. • Check that the finger holder is properly attached to the patient. If the finger holder is properly attached but this message still appears, the circulation in the area being measured may not be good. If this occurs, warm up the measurement location.
The MeasurementValue andflash alternately • The pulse is weak and the pulse signals required for the means urement are not obtained. The measurement value is displayed,  however, the accuracy of the means urement values can not be guaranteed. Thus, the measured value must be considered as guidance only. • Attach the finger holder to the body correctly. If this message is displayed when the unit is attached to the patient correctly, the measurement conditions are regarded as blood circulation or other circulatory problems. If this occurs, warm up the measurement locations.• In particular, when the pulse is weak, this error tends to occur. For improved measurement accuracy, if the finger holder is exposed to strong light, wrap it with a piece of black cloth, etc. Also, make sure that the patient rests calmly to avoid the influence of body movement.
The Measurement Value and • Motion artifact • Attach the finger holder to the patient properly. If this message still reappears even though the finger holder is attached properly, keep the measuring point as stationary as possible.
• The pulse rate exceeds the upper limit (250 bpm) of the measurement range. • Measurement cannot be performed when the upper limit of the measurement range is exceeded.

REFERENCE

Measurement PrincipleOxygen Saturation Monitor PULSOX-2 is a photometric instrument that non-invasively and continuously measures the oxyhemoglobin saturation ofarterial blood (SpO2) and the pulse rate. SpO2 is described by the equation:

whereC (Hb): Concentration of reduced hemoglobinC (HbO2): Concentration of oxyhemoglobinThe light-absorption characteristics of reduced hemoglobin (Hb) are very different from those of oxyhemoglobin. The PULSOX-2 measures the changes in the absorption of red and infrared lights passing through the tissue to determine the SpO2 of the blood. Thus, this method is free from the effects of skin color, muscles, bones, and veins.Spectral Absorption of Hb and HbO2

Relation between Oxygen Saturation and Partial PressureThe relation between oxygen saturation (SpO2, %) and oxygen partial pressure (PaO2, Torr, or mmHg) is shown in the graph below. SpO2 is the oxygen saturation as measured by pulse oximeters.Oxygen Saturation vs. Oxygen Partial Pressure

The curve of the above graph may shift to the right or left according to the pH of the blood or the body temperature. (Shift to right: acidosis, high body temperature; shift to left: alkalosis, low body temperature)

NOTE 1  At 80MHz and 800MHz, 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.

a Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephone and land mobile radios, amateur radio, AM, and FM radio broadcast, and TV broadcast 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 PULSOX-2 is used exceeds the applicable RF compliance level above, the PULSOX-2 should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the PULSOX-2.b Over the frequency range 150kHz to 80MHz, field strengths should be less than 3V/m.
