1. Einleitung
The CONTEC CMS50D2 Pulse Oximeter is a non-invasive device designed for measuring the oxygen saturation of arterial hemoglobin (SpO2) and the pulse rate. This device is intended for spot-checking and continuous monitoring of adult and pediatric patients in home and clinical environments. It provides a quick and accurate assessment of respiratory function.
The concentration of oxygen determines the percentage of hemoglobin in arterial blood that is saturated with oxygen, making it an important parameter for evaluating respiratory function. The device is small, lightweight, and portable, making it convenient for use anywhere.
2. Sicherheitshinweise
Please read all safety warnings and instructions carefully before using this device. Improper use may result in inaccurate readings or device damage.
- Verwenden Sie das Pulsoximeter nicht in einer MRT- oder CT-Umgebung.
- Do not use the device in environments with flammable anesthetics.
- The device is not intended for continuous monitoring of patients requiring constant supervision.
- Halten Sie das Gerät von Wasser und Feuchtigkeit fern.
- Consult a medical professional for interpretation of readings and before making any medical decisions.
3. Produktmerkmale

6. Bedienungsanleitung
Follow these steps to obtain accurate readings:
- Stellen Sie sicher, dass die Batterien richtig eingelegt sind.
- Öffne dieamp des Oximeters.
- Insert one of your fingers (preferably the index, middle, or ring finger) into the rubber opening of the oximeter, ensuring the nail surface is facing upwards towards the display.
- Lassen Sie die clamp, allowing the oximeter to securely hold your finger.
- Drücken Sie den Ein-/Ausschalter oben am Gerät, um es einzuschalten.
- Keep your hand still during the measurement. Do not shake your finger.
- The readings for SpO2 and pulse rate will appear on the display within a few seconds.
- To change the display orientation or brightness, briefly press the power button while the device is on.
- The device will automatically power off after 5 seconds of inactivity or if the finger is removed.

7. Informationen anzeigen
The OLED display provides the following information:
- SpO2: Peripheral Oxygen Saturation (percentage). This indicates the percentage of hemoglobin in your blood that is saturated with oxygen. Normal values typically range from 95% to 100%.
- PRbpm: Pulse Rate (beats per minute). This is the number of times your heart beats per minute. Normal adult resting heart rate ranges from 60 to 100 bpm.
- Pulsbalkendiagramm: A vertical bar graph indicating the strength of the pulse.
- Plethysmograph (Waveform): A graphical representation of the pulse, showing blood flow through the finger.
- Batterieanzeige: Zeigt die verbleibende Akkulaufzeit an.
8. Wartung und Pflege
8.1. Reinigung
Clean the surface of the oximeter before and after each use. Use a soft cloth dampened with medical alcohol (70% ethanol or isopropanol) to wipe the surface. Do not immerse the device in liquid.
8.2. Speicherung
Bewahren Sie das Gerät an einem kühlen, trockenen Ort, vor direkter Sonneneinstrahlung und extremen Temperaturen geschützt auf. Wenn das Gerät längere Zeit nicht benutzt wird, entfernen Sie die Batterien, um ein Auslaufen zu verhindern.
9. Fehlerbehebung
| Problem | Mögliche Ursache | Lösung |
|---|---|---|
| Keine Anzeige nach dem Einschalten | Die Batterien sind leer oder falsch eingelegt. | Tauschen Sie die Batterien aus oder setzen Sie sie unter Beachtung der Polarität korrekt wieder ein. |
| Ungenaue Messwerte | Finger not inserted properly; patient movement; strong ambient light; nail polish or artificial nails. | Re-insert finger correctly; remain still; shield from strong light; remove nail polish/artificial nails. |
| "Finger Out" or "Error" message | Finger not detected or poor signal quality. | Ensure finger is fully inserted and still. Try a different finger. |
| Display ist dunkel | Niedriger Batteriestand oder falsche Helligkeitseinstellung. | Replace batteries. Adjust brightness by pressing the power button. |
