1. Introduction
The Salter Labs High-Flow Humidifier is designed to provide humidification for oxygen therapy at flow rates ranging from 6 to 15 Liters Per Minute (LPM). This device is suitable for use with high-capacity oxygen concentrators, wall outlet source gas, or other applications requiring high oxygen flow rates. It features a pressure relief valve and a down spout diffuser for efficient operation.
Key Features:
- Designed for high flow rates (6-15 LPM).
- Integrated pressure relief valve that automatically resets.
- Low resistance, high output diffuser head.
- Large quad-style wingnut connector for secure attachment.
- Clearly marked minimum and maximum water levels on the jar.
2. Setup
Follow these steps to prepare your High-Flow Humidifier for use:
- Unpack: Carefully remove the humidifier from its packaging and inspect for any damage.
- Fill with Water: Unscrew the humidifier jar from the lid. Fill the jar with distilled or sterile water up to the maximum fill line indicated on the jar. Do not overfill.
- Secure Lid: Screw the lid back onto the jar, ensuring it is securely tightened to prevent leaks.
- Connect to Oxygen Source: Attach the humidifier to your oxygen source (e.g., oxygen concentrator, wall outlet) using the large quad-style wingnut connector. Ensure a tight, leak-free connection.
- Connect Oxygen Tubing: Attach the oxygen delivery tubing (e.g., face mask tubing, cannula tubing) to the outlet port on the humidifier lid.

3. Operating Instructions
Once the humidifier is set up, follow these guidelines for operation:
- Initiate Oxygen Flow: Turn on your oxygen source and set the prescribed flow rate, ensuring it is within the 6-15 LPM range for this humidifier.
- Verify Humidification: Observe the humidifier jar. Bubbling should be visible, indicating that oxygen is passing through the water and humidification is occurring.
- Monitor Water Level: Regularly check the water level in the jar. Refill with distilled or sterile water as needed, ensuring it remains between the minimum and maximum fill lines.
- Pressure Relief: The humidifier is equipped with an audible pressure relief alert. If an occlusion occurs in the oxygen delivery system, this valve will activate to release excess pressure, producing an audible sound. Address any occlusions immediately.
4. Maintenance
Proper maintenance ensures optimal performance and hygiene:
- Daily Cleaning: Disassemble the humidifier daily. Wash the jar and lid with warm, soapy water. Rinse thoroughly with clean water.
- Disinfection: For disinfection, soak the components in a solution of one part white vinegar to three parts water for 30 minutes, or use a medical-grade disinfectant as recommended by your healthcare provider. Rinse thoroughly after disinfection.
- Drying: Allow all components to air dry completely before reassembly.
- Water Replacement: Always use fresh distilled or sterile water when refilling the humidifier. Do not reuse water.
- Inspection: Periodically inspect the humidifier for any signs of wear, cracks, or damage. Replace the unit if any damage is observed.
5. Troubleshooting
Refer to the following table for common issues and their solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No bubbling in jar | Oxygen flow too low; humidifier not connected properly; tubing kinked or disconnected. | Increase oxygen flow to recommended range (6-15 LPM); ensure all connections are secure; check and clear tubing. |
| Audible pressure relief alert activates | Occlusion in oxygen delivery tubing or cannula; excessive oxygen flow. | Check for kinks or blockages in tubing/cannula and clear them; ensure oxygen flow rate is within the specified range. |
| Water leakage | Lid not tightened properly; jar cracked; water level too high. | Ensure lid is securely tightened; inspect jar for damage and replace if necessary; reduce water level to below the maximum fill line. |
