When using an oxygen concentrator, the air delivered is typically dry, which can cause discomfort in the delicate tissues of the nose and throat. The continuous flow of dry oxygen can lead to the drying out of mucosal membranes. This can cause irritation, dryness, and sometimes minor nosebleeds. To counteract these effects, a humidifier bottle is attached to introduce moisture into the oxygen stream before it reaches the user.
Gathering Necessary Supplies
Before beginning the setup, gather the primary components: the oxygen concentrator unit and a bubble humidifier bottle designed for this purpose. These bottles are usually made of durable plastic and feature a pressure-relief valve built into the lid as a safety measure. You will also need a short connector piece, often called a nipple adapter, which bridges the concentrator’s outlet port and the humidifier bottle.
The most important supply is the type of water used to fill the bottle. Only distilled or sterile water should ever be used in the humidifier reservoir. Tap water, filtered water, or bottled drinking water contains minerals like calcium and magnesium that precipitate out of the water as it evaporates.
These deposits accumulate as scale on the interior surfaces, decreasing the bottle’s efficiency and lifespan. Furthermore, the non-sterile nature of tap water introduces the potential for bacterial contamination. Using distilled water prevents mineral buildup and minimizes the risk of inhaling harmful microbes directly into the respiratory system. Always confirm that the bottle is compatible with your specific concentrator model.
Connecting the Humidifier Bottle
The first step in assembly is preparing the humidifier bottle by adding distilled water. Locate the maximum fill line clearly marked on the side of the plastic reservoir. Carefully pour the distilled water into the bottle, ensuring the water level does not exceed this designated line. Overfilling the container can lead to water being inadvertently pushed through the tubing and reaching the patient.
Once the water is at the correct level, securely fasten the lid or cap onto the bottle. It is important to twist the cap until it is snug to create an airtight seal. Avoid overtightening, which could damage the plastic threads. The proper seal is required for the oxygen pressure to build up and force the gas through the water to create the humidification effect.
Next, attach the short nipple adapter to the oxygen concentrator’s dedicated oxygen outlet port. This port is typically located on the front panel of the machine. The adapter should fit firmly into the opening, creating a seal that prevents any gas from escaping at this junction.
Now, take the filled and sealed humidifier bottle and connect it directly to the other end of the nipple adapter. The bottle usually screws onto the adapter; gently turn the bottle clockwise until the threads are fully engaged. Ensure the bottle is vertical and stable to prevent accidental tipping during operation.
The final connection step involves attaching the patient’s oxygen tubing or nasal cannula. This long, thin tubing connects to the oxygen outlet port located on the top of the humidifier bottle’s cap. Press the connector end of the tubing firmly onto the humidifier outlet until it is securely seated.
With all connections secured, the system is ready for a preliminary check. Turn on the oxygen concentrator and set the flow rate to the prescribed setting. The flow of oxygen should immediately cause bubbling within the water reservoir of the humidifier bottle. This audible bubbling confirms that the oxygen is successfully passing through the water and being humidified. If no bubbling is heard, immediately check all connections for leaks, starting with the lid seal and the connection point to the concentrator. A lack of bubbling indicates a flow obstruction or a leak that must be corrected before the oxygen is administered.
Daily Care and Cleaning
Maintaining the humidifier bottle daily is necessary to prevent the growth of microorganisms. At least once every 24 hours, the water in the reservoir should be replaced, never simply topped off. Emptying the remaining water removes accumulated contaminants or dissolved gases. After discarding the old water, rinse the interior of the bottle thoroughly with fresh distilled water before refilling it to the maximum line.
A more comprehensive cleaning protocol should be followed at least once a week. Begin by disassembling the bottle, separating the cap from the reservoir. The pieces can be washed using a mild dish soap and warm water, scrubbing the interior surfaces gently with a clean brush if necessary.
Alternatively, a disinfecting solution can be created using a mixture of white vinegar and water, typically 1 part vinegar to 3 parts water. Soak the bottle and cap in this solution for 30 minutes to sanitize the components. Following either the soap wash or the vinegar soak, rinse all components extensively under running tap water for several minutes. Residual soap or vinegar left in the bottle can cause irritation if inhaled.
Once fully rinsed, allow the reservoir and cap to air dry completely before reassembly. Placing the pieces on a clean, dry towel and allowing natural air circulation ensures that no moisture remains. Avoid using heat sources or placing them in direct sunlight, which could warp the plastic. The humidifier bottle has a limited service life and should be replaced periodically, generally every six months. Replace it sooner if the plastic becomes cloudy, cracked, or if the pressure-relief valve appears damaged.
