1. BEFORE OPERATION Safety Notes CAUTION: Federal law restricts this device to sale by or on the order of a physician. The PULSOX-2 is a medical instrument, so instructions given by a doctor must be adhered to. The instrument is designed for measurement of the oxygen saturation (SpO2) of arterial blood and the pulse rate. Do not use it for any other purposes, such as warning of sleep apnea and breathing abnormalities. Package Contents Make sure that all the following items are supplied with the instrument.
2. NAMES OF PARTS ■ Main unit Finger holder Battery cover lock Battery cover Strap eyelet Display Thumb rest Battery cover: Open or close this cover when replacing the batteries with new ones. Battery cover: It is used to lock the battery cover. lock Strap eyelet: Attach the neck strap to this hook. Finger holder: Holds finger when inserted for measurement. A light source is located in the upper side, and a sensor in the lower side. Thumb rest: Put the thumb here when you hold this instrument.
3. NOTES ON USE • • • • • • • • • • • 6 This instrument should be used in areas with an ambient temperature of 0 to 40°C (32 to 104°F) and a relative humidity of 30 to 95%, with no condensation. This is a precision instrument. To avoid the possibility of it being damaged, the instrument should not be dropped nor should heavy objects be placed on top of it.
This equipment has been tested and found to comply with the limits for medical devices to the IEC 60601-1-2:2001, Medical Device Directive 93/42/EEC . These limits are designed to provide reasonable protection against harmful interference in a typical medicitl installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to other devices in the vicinity.
4. OPERATING METHOD Preparations (1) Installing Batteries (Two AAA-size batteries are required.) 1. Push the battery cover, and unlock the battery cover lock. 1 2. Open the battery cover. 3. Insert two AAA-size batteries into the battery chamber. 2 3 4. Close the battery cover and hold it with a finger.
5. Close the battery cover lock until it clicks. • The batteries will last approximately 80 hours. • The battery mark will begin to blink when the battery power is low. 5 Notes on Use • Battery replacement is the Only User Serviceable item. • When replacing the batteries with new ones, do not mix battery types or ages. • If the instrument will not be used for a long period of time, remove the batteries from the battery chamber. Also remove the batteries as soon as possible if they are dead.
Measurements Measurements must be taken with the index finger placed in the finger holder. This instrument must be held tightly. Put the thumb only on the thumb rest. You must not put the thumb on other positions. Don't take the pressure which is unnecessary for the forefinger. Those are important for the accurate measurement. 1. Open the finger holder. 2. Insert the index finger and release the finger holder. • Opening the finger holder will start measurement automatically.
Safety Notes This finger holder is designed only for use on the fingers of adults, so it should not be used on any other body parts. Never secure the finger holder with tape or such like. Doing so may cause hemostasia or dropsy. Notes on Use • • • • Remove nail polish before taking measurements. If no measurement values are displayed, attach the finger holder to a thinner finger to take measurements. It may not be possible to take measurements in case of blood circulation or blood stream problems.
Ending Measurements 1. Open the finger holder and remove the finger. • Measurement will stop automatically, and the display will go off after 10 seconds. Notes on Use • 12 If the instrument will not be used for a long period of time, remove the batteries from the battery chamber.
How to Read the Measurement Values Pulse level meter: Indicates the pulse level in 8 levels (0 to 10%, full scale if 10% or higher). The pulse level is defined as follows. (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 meter constantly indicates level 2 or higher.
Back Light The backlight will light up automatically when the surroundings become dark. When backlight isn’t turned by the bright surroundings, cover the backlight sensor window with finger. Backlight sensor window • Once the backlight is lit, it will remain lit until measurement stops. • When battery mark is blinking, backlight isn’t turned on. Please replace the battery.

6. In Case of Malfunction • If a malfunction occurs, contact the nearest authorized service facility. Never disassemble the unit or attempt to repair it yourself. 7. Maintenance and Storage • • This instrument should be stored at temperatures of between –10 and 60°C (14 and 140°F) at 30 to 95% relative humidity. Do not store this instrument in areas subject to high temperatures or high humidity, and do not subject this instrument to sudden temperature changes which may result in condensation.
10. SPECIFICATIONS PULSOX-2 ■ Dual-wavelength pulse-type oximeter ■ Functions: • Measuring range: SpO2: 0 to 100% Pulse rate: 20 to 250 bpm • Accuracy: SpO2 ±2% (SpO2:70 to 100%, 1 s.d.
11. REFERENCE Measurement Principle Oxygen Saturation Monitor PULSOX-2 is a photometric instrument that non-invasively and continuously measures the oxyhemoglobin saturation of arterial blood (SpO 2) and the pulse rate. SpO2 is described by the equation: C (HbO2) C (HbO2) + C (Hb) SpO2 = × 100 (% SpO2) where C (Hb): Concentration of reduced hemoglobin C (HbO2): Concentration of oxyhemoglobin The light-absorption characteristics of reduced hemoglobin (Hb) are very different from those of oxyhemoglobin.
Relation between Oxygen Saturation and Partial Pressure The 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 Oxygen Partial Pressure SpO2 % 100 90 85 80 70 60 50 40 Adult hemoglobin 30 pH=7.
