CONTEC CMS50D2 Digital Finger Pulse Oximeter User Manual

1. Introduction

The CONTEC CMS50D2 Digital Finger Pulse Oximeter is designed for non-invasive spot-check measurement of functional oxygen saturation of arterial hemoglobin (SpO2), pulse rate (PR), and Perfusion Index (PI). This device is suitable for use at home, in clinics, and hospitals. It features a clear display with adjustable brightness, pulse waveform, and automatic power-saving standby.

Key Features:

• Accurate SpO₂ Monitoring: Real-time blood oxygen saturation (SpO₂) display helps track oxygen levels quickly and reliably.
• Pulse Rate with Waveform & Bar Graph: Displays pulse rate (PR) along with a visual bar graph and pulse waveform.
• Perfusion Index (PI) Display (Optional): Provides insight into blood circulation and signal strength.
• Smart Battery Indicators: Low-battery alert and battery power level display.
• Auto Power-Saving Standby: Automatically switches to standby mode when not in use.
• Multiple Display Modes & Adjustable Brightness: User-friendly screen with adjustable brightness for clear visibility.

2. Safety Information

• Consult a medical professional for interpretation of readings. This device is not intended for continuous monitoring or self-diagnosis.
• Do not use the oximeter in an MRI or CT environment.
• Keep out of reach of children.
• Do not use on infants or individuals with very small fingers.
• Avoid using the device on the same arm as a blood pressure cuff or arterial catheter.
• Do not immerse the device in water or other liquids.
• Dispose of batteries according to local regulations.

6. Maintenance and Storage

6.1 Cleaning

• Clean the surface of the oximeter with a soft cloth dampened with 70% isopropyl alcohol.
• Do not spray cleaning solutions directly onto the device.
• Ensure the device is completely dry before use.

6.2 Battery Replacement

• When the low-battery indicator appears on the display, replace the batteries promptly. Follow the battery installation steps in Section 4.1.

6.3 Storage

• Store the oximeter in a cool, dry place, away from direct sunlight and extreme temperatures.
• If the device will not be used for an extended period, remove the batteries to prevent leakage.

7. Troubleshooting

• No Reading or Inaccurate Reading:
  • Ensure the finger is fully inserted into the oximeter.
  • Check that the fingernail is facing upwards.
  • Keep the hand still during measurement.
  • Verify battery levels and replace if necessary.
  • Avoid strong ambient light.
  • Ensure the finger is not too cold or has nail polish.
• Display is Dim:
  • Adjust the brightness setting.
