Key Features:
- Accurate oxygen concentration measurement.
- Robust construction, typically utilizing stainless steel components.
- Electrical signal output for seamless integration with compatible medical devices.
- Measuring range: 21% to 100% O2.
4. Setup
Follow these steps for proper installation of the OOM202 oxygen sensor:
- Unpacking: Carefully remove the sensor from its packaging. Inspect for any visible damage. If damage is present, do not use the sensor and contact your supplier.
- Compatibility Check: Verify that the OOM202 sensor is compatible with your specific medical device. Refer to the device's manual for sensor requirements.
- Connection: Connect the sensor to the designated port on your medical equipment. Ensure a secure and proper fit. The sensor typically connects via a threaded port or a specific connector designed for oxygen sensors.
- Mounting: If your equipment or application requires it, ensure the sensor is mounted securely. While the sensor itself is compact, the 'Wall Mount' specification refers to the typical mounting method for the overall system it integrates with, or a specific mounting feature on the sensor's housing.
- Initial Calibration/Test: After connection, perform any required calibration or system self-tests as instructed by your medical equipment's operating manual. This ensures accurate readings.
5. Operating Instructions
Once installed and calibrated, the OOM202 sensor operates automatically in conjunction with your medical equipment. Refer to your equipment's manual for specific operational procedures.
- Monitoring: The sensor continuously measures oxygen concentration, providing real-time data to the connected device's display.
- Reading Interpretation: Always interpret oxygen readings in the context of the patient's condition and the medical equipment's specifications.
- Alarm Limits: Ensure appropriate alarm limits are set on the medical equipment to alert personnel to deviations in oxygen concentration.
6. Maintenance
Proper maintenance ensures the longevity and accuracy of your OOM202 sensor.
- Cleaning: Clean the exterior of the sensor with a soft, damp cloth. Use mild, non-abrasive cleaning agents if necessary. Do not immerse the sensor in liquids or use harsh chemicals.
- Storage: When not in use, store the sensor in a cool, dry place, away from direct sunlight and extreme temperatures. Keep it in its original packaging or a protective container.
- Replacement: Oxygen sensors have a finite lifespan. The OOM202 sensor should be replaced periodically according to the manufacturer's recommendations or when it fails calibration or provides inconsistent readings. Consult your medical equipment's service manual for specific replacement intervals.
7. Troubleshooting
If you encounter issues with your OOM202 sensor, consider the following troubleshooting steps:
- No Reading/Inaccurate Reading:
- Check all connections to ensure they are secure.
- Verify sensor compatibility with the connected device.
- Perform a system calibration as per your medical equipment's manual.
- Inspect the sensor for visible damage.
- If the sensor is old, it may have reached the end of its lifespan and require replacement.
- Intermittent Readings:
- Check for loose connections.
- Ensure the sensor is not exposed to excessive vibration or movement.
If troubleshooting steps do not resolve the issue, contact your medical equipment service provider or the sensor supplier for assistance.
