2.3 Personal Information Setup
Before first use, or for a new user, it is essential to input personal information to ensure accurate and personalized readings. This typically includes:
- Height
- Age
- Gender
- Ethnicity (if applicable for specific reference values)
Refer to the on-screen menu of the device to navigate to the personal settings and input the required data.
3. Operating Instructions
3.1 Performing a Spirometry Test
- Ensure the device is powered on and a clean mouthpiece is attached.
- Sit upright in a comfortable position.
- Take a deep breath, filling your lungs completely.
- Place your lips tightly around the mouthpiece, ensuring no air escapes.
- Exhale as hard and as fast as you can, emptying your lungs completely. Continue exhaling for at least 6 seconds, or until instructed by the device.
- Repeat the test as necessary, typically three times, to obtain consistent readings.
The device will display key parameters such as FVC, FEV1, FEV1/FVC, and PEF after each test. It may also provide a health status indication based on these measurements compared to predicted values for your personal information.
3.2 Data Management
The SP70B spirometer features data memory and case review functions. You can browse previous test results directly on the device. For more detailed analysis and long-term tracking, the device supports Bluetooth transmission to compatible software or applications.
Refer to the device's on-screen menu or accompanying software instructions for pairing and data transfer procedures.
4. Maintenance
4.1 Cleaning the Device and Mouthpiece
Regular cleaning is essential for hygiene and accurate operation.
- Device Body: Wipe the main unit with a soft, damp cloth. Do not immerse the device in water or use abrasive cleaners.
- Mouthpiece: The mouthpiece should be cleaned or replaced after each use, especially if used by multiple individuals. Disposable mouthpieces are recommended. If using a reusable mouthpiece, clean it thoroughly with mild soap and water, rinse, and allow it to air dry completely before storage or next use.
