Riester 132880 Pulse Oximeter ri-fox N User Manual

Riester 132880 Pulse Oximeter ri-fox N

General Description

• Oxygen Saturation is a very important parameter for the Respiratory Circulation System. Many respiratory diseases can result in oxygen saturation being lowered in human blood. Additionally, the following factors can reduce oxygen saturation: organ dysfunction caused by anesthesia, intensive postoperative trauma, injuries caused by some medical examinations. That situation might result in light-headedness, asthenia, and vomiting. Therefore, it is very important to know the oxygen saturation of a patient so that doctors can find problems in a timely manner.
• The fingertip pulse oximeter ri-fox N features small size, low power consumption, convenient operation and portability. It is only necessary for a patient to put one of his fingers into the fingertip photoelectric sensor for diagnosis, and a display screen will show oxygen saturation. It has been proven in clinical experiments that it also features high precision and repeatability.

Product Operation Scope

• ri-fox N is a portable non-invasive, spot-check, oxygen saturation of arterial hemoglobin (SpO2) and pulse rate of adult and pediatric patients at home and hospital (including clinical use in internal medicine/surgery, anesthesia, etc). The device is not intended for continuous monitoring.
• The ri-fox N requires no routine calibration or maintenance other than replacement of batteries.

Precautions for use

1. Do not use the pulse oximeter in an MRI or CT environment

2. Do not use the pulse oximeter in situations where alarms are required. The device has no alarms.

3. Explosion hazard: Do not use the pulse oximeter in an explosive atmosphere.

4. The pulse oximeter is intended only as an adjunct in patient assessment. It must be used in conjunction with other methods of assessing clinical signs and symptoms.

5. Check the pulse oximeter sensor application site frequently to determine the positioning of the sensor and circulation and skin sensitivity of the patient.

6. Before use, carefully read the manual.

7. ri-fox N has no SpO2 alarms; it is not for continuous monitoring, as indicated by the symbol.

8. Prolonged use or the patient’s condition may require changing the sensor site periodically. Change sensor site and check skin integrity, circulatory status, and correct alignment at least every 4 hours.

9. Inaccurate measurements may be caused by autoclaving, ethylene oxide sterilizing, or immersing the sensors in liquid may cause inaccurate readings.

10. SpO2 measurements may be adversely affected in the presence of high ambient light. Shield the sensor area if necessary.

11. Excessive patient movement may cause inaccurate readings.

12. Placement of a sensor on an extremity with a blood pressure cuff, arterial catheter, or intravascular line may cause inaccurate readings.

13. Fingernail polish or false fingernails may cause inaccurate SpO2 readings.
    Contraindication

14. Significant levels of dysfunctional hemoglobins (such as carbonxy-hemoglobin or methemoglobin) may cause inaccurate readings

15. Intravascular dyes such as indocyanine green or methylene blue may cause inaccurate readings

16. Venous pulsations may cause inaccurate readings.

17. Hypotension, severe vasoconstriction, severe anemia or hypothermia may cause inaccurate readings.

18. Cardiac arrest or shock may cause inaccurate readings.
    No side effects known
    Follow local ordinances and recycling instructions regarding disposal or recycling of the device and device components, including batteries.

Product specifications

1. Easy to use.
2. Small in volume, light in weight.
3. Low power consumption.
4. Low voltage warning will be indicated in visual window when battery voltage is low.
5. The product will automatically be powered off when no signal is registered for longer than 8 seconds.

Operation Instructions

1. Install two AAA batteries into the battery cassette, and then close its cover.
2. Open the clamp as shown in the picture below.
3. Insert one finger completely into the opening of the pulse oximeter.
4. Press the power switch once on the front panel.
5. The patient’s finger should remain still while the pulse oximeter is working.
6. Read corresponding data from display screen.
   When you insert a finger into the Oximeter, your nail surface must be upward.

Brief Description of Front Panel

The Pulse Bar graph displays the strength of the pulse rate signal. The height of the bar graph shows the patient’s pulse strength.

Battery Installation

1. Put the two AAA batteries into battery cassette in correct polarities.
2. Press the button down along the arrow and push the battery cover shown as below:

Maintenance and Storage

1. Replace batteries in time when low voltage lamp is lighted.
2. Clean surface of the ri-fox N before it is used in diagnosis for patients.
3. Remove batteries inside the battery cassette if the oximeter will not be used for a long time.
4. It is best to preserve the product in a place where ambient temperature is –20~55°C and humidity is <93%, no condensation.
5. It is recommended that the product should be kept in a dry environment anytime. A wet ambient might affect its lifetime and even might damage the product.
6. Please follow the law of the local government to deal with used batteries.

Calibrating the Oximeter

1. The functional tester cannot be used to assess the accuracy of the oximeter.
2. The test method used to establish the SpO2 accuracy is clinical testing. The oximeters used to measure the arterial haemoglobin oxygen saturation levels are compared to the levels determined from arterial blood sampling with a CO-oximeter.
3. Index 2 that is made by Biotek company is a function tester. Set Tech to 1, R curve to 2, and then users can use this particular calibration curve to measure the oximeter.
