3. Setup
Follow these steps to set up your Sonmol Respiratory Exerciser:
- Unpack Components: Carefully remove all items from the travel case.
- Attach Blowing Tube: Insert the blowing tube firmly into the designated opening on the main breathing exercise device.
- Connect Manometer (Optional for MEP Measurement): If you intend to measure your Maximal Expiratory Pressure (MEP), connect one end of the manometer connection tube to the manometer and the other end to the small port on the main device, typically marked 'OUT' or for pressure measurement.
- Nose Clip: The nose clip is used to ensure all air passes through the device during exercise. Place it on your nose before starting your training session.
4. Operating Instructions
4.1. Adjusting Resistance Levels
The device features 5 adjustable resistance levels for both inhalation and exhalation. A higher level setting indicates greater resistance.
- Select Inhalation Resistance: Rotate the dial marked 'IN' or for inhalation to your desired resistance level (1-5).
- Select Exhalation Resistance: Rotate the dial marked 'OUT' or for exhalation to your desired resistance level (1-5).
- Starting Level: It is recommended to begin exercising at Level 1 and gradually increase the resistance as your respiratory muscles strengthen.

Image 4.1: The device offers 5 distinct resistance levels for both inhaling and exhaling, allowing for progressive training.

4.2. Using the Manometer to Measure Maximal Expiratory Pressure (MEP)
The manometer allows you to track your respiratory performance and monitor improvement over time.
- Set to Test Level 'T': Before measuring MEP, ensure both the inhalation ('IN') and exhalation ('OUT') resistance dials on the main device are set to the 'T' (Test) level. This creates a sealed environment for accurate measurement.
- Connect Manometer: Ensure the manometer is correctly connected to the device via the connection tube.
- Perform Measurement: Take a deep breath, then exhale forcefully and steadily into the blowing tube. The manometer needle will indicate your Maximal Expiratory Pressure (MEP).
- Record Results: Note down your MEP reading to track your progress.

4.3. Recommended Training Schedule
For optimal results, follow this general training guideline:
- Duration: Practice for 5 to 10 minutes per session.
- Frequency: Repeat 2 to 3 times per day.
- Consistency: Consistent practice is key to strengthening respiratory and abdominal muscles and increasing lung capacity.

5. Maintenance and Cleaning
Proper maintenance ensures the longevity and hygienic use of your device.
- Disassembly: After each use, disassemble the blowing tube and manometer connection tube from the main device.
- Washing: Wash all removable parts (blowing tube, connection tube, nose clip) with warm water and mild soap. Rinse thoroughly.
- Cleaning Main Unit: Wipe the main breathing exercise device with a damp cloth. Do not submerge the main unit in water.
- Drying: Allow all components to air dry completely before reassembling or storing.
- Storage: Store the device and its components in the provided travel case in a clean, dry place away from direct sunlight and extreme temperatures.
6. Troubleshooting
If you encounter issues with your Sonmol Respiratory Exerciser, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Difficulty breathing through the device. | Resistance level is too high. | Reduce the inhalation and/or exhalation resistance level. Start at Level 1. |
| Manometer not showing a reading or inaccurate reading. | Manometer not connected properly; 'T' level not set; air leak. | Ensure manometer connection tube is firmly attached. Set both 'IN' and 'OUT' dials to 'T' for MEP measurement. Check for any loose connections. |
| Device feels dirty or has an odor. | Insufficient cleaning. | Disassemble and thoroughly clean all washable parts with warm water and mild soap. Air dry completely. |
