Starting home oxygen therapy can feel unfamiliar at first. From choosing the right location for your equipment to connecting the nasal cannula and maintaining the oxygen concentrator, there are several important steps to understand before beginning treatment.
A home oxygen concentrator is designed to provide a continuous supply of concentrated oxygen from the surrounding air. For people who have been prescribed supplemental oxygen for use at home, learning how to operate and care for the equipment correctly can make daily oxygen therapy easier and more manageable.
This beginner-friendly guide explains how to set up an oxygen concentrator for home use, how to use it safely, and how to maintain the equipment for reliable operation.
What Is a Home Oxygen Concentrator?
A home oxygen concentrator is an electrically powered device that takes in room air and separates oxygen from other gases. Most modern concentrators use Pressure Swing Adsorption (PSA) technology, which uses molecular sieve material to separate nitrogen from the air and deliver concentrated oxygen through an outlet.
The VARON Home Oxygen Concentrator 105W Pro Wheel uses PSA technology and provides continuous oxygen flow. It offers adjustable flow from 1 to 9 L/min and displays information such as oxygen purity, oxygen flow and total operating time.
For beginners, however, the most important consideration is not simply how much oxygen a machine can deliver. The appropriate flow rate depends on the individual's prescribed oxygen therapy.
How to Set Up a Home Oxygen Concentrator
Setting up an oxygen concentrator involves more than simply plugging it in. Proper placement, ventilation, tubing connections and operating settings all contribute to safe and effective use.
Step 1: Choose a Suitable Location
Start by selecting a clean, dry and well-ventilated area for the concentrator.
Keep the machine:
- Upright and stable
- At least 10 cm away from walls and surrounding objects
- Away from direct sunlight
- Away from heaters and other heat sources
- Away from open flames and fire hazards
- Away from wet or unsheltered areas
- Free from objects covering the air vents
Good airflow is particularly important because an oxygen concentrator draws in surrounding air and generates heat while operating. Blocking the air inlet or outlet can interfere with operation and may contribute to overheating.
Do not place water containers, oil, heavy objects or other items on top of the machine. Avoid storing anything underneath it that could obstruct the air vents.
Keep the concentrator upright
An oxygen concentrator should remain upright during normal operation. If you need to move it, handle it carefully and avoid tipping or overturning the equipment.
For the VARON Home Oxygen Concentrator 105W Pro Wheel, the recommended inclination is no more than 5 degrees.
Step 2: Inspect the Equipment Before Use
Before using a new oxygen concentrator, inspect the machine and accessories.
Check for:
- Visible damage to the concentrator
- Damaged power cords
- Missing accessories
- Damaged oxygen tubing
- A properly assembled humidification bottle, if one is being used
- A clean and correctly installed filter
If something appears damaged or missing, contact the equipment provider before operating the machine.
Never attempt to open the concentrator's housing yourself. Internal components, electrical systems and compressor assemblies should be serviced by appropriately qualified personnel.
Step 3: Prepare the Humidification Bottle
Some oxygen concentrator setups include a humidification bottle to add moisture to the oxygen stream.
For the VARON 105W Pro Wheel, gently remove the humidification bottle and take off the rubber cap. Fill it with cold purified water, making sure the water does not exceed the maximum level indicated on the bottle.
Replace the cap securely and reinstall the bottle.
The concentrator can also operate without water in the humidification bottle. If you choose to use humidification, proper cleaning and water replacement are important parts of routine maintenance.
Humidification bottle care
For regular use:
- Replace the water every day.
- Clean the bottle approximately once a week.
- Rinse it thoroughly with clean water.
- Clean the rubber cap.
- Make sure the internal tube and aerator remain clear.
Never allow the bottle to become excessively dirty or blocked, as this can interfere with oxygen flow.
Step 4: Connect the Power
Once the concentrator is positioned correctly, connect the power cord to the machine and an appropriate electrical outlet.
Before switching the device on, make sure:
- The power cord is properly connected.
- The outlet is suitable for the machine.
- The concentrator is positioned securely.
- Air vents are unobstructed.
If your household power supply is unstable, appropriate electrical protection may be necessary. For the VARON 105W Pro Wheel, a voltage regulator is recommended when the power supply is unstable.
Avoid using unsuitable electrical connections or overloaded outlets.
Step 5: Turn On the Oxygen Concentrator
Switch the main power switch to the "I" position to place the machine in standby mode.
Then press the ON/OFF button to start normal operation.
As the concentrator starts, you may hear periodic operating sounds from the compressor and internal system. These sounds can be normal during operation.
The control panel provides useful information, including:
- Oxygen flow
- Oxygen purity
- Running time
- Total usage time
- Operating indicators
Take a moment to become familiar with these controls before beginning regular use.
Step 6: Set the Prescribed Oxygen Flow
This is one of the most important steps in home oxygen therapy.
The VARON 105W Pro Wheel allows the oxygen flow to be adjusted from 1 to 9 L/min. However, having a range of available settings does not mean every setting is appropriate for every person.
Your healthcare professional should determine your prescribed oxygen flow.
Once you have received your prescribed setting, use the Flow control on the concentrator to select it. Before connecting the nasal cannula, confirm that oxygen is flowing from the oxygen outlet.
Never adjust your oxygen flow based on how you feel
Increasing or decreasing supplemental oxygen without professional guidance may be inappropriate for your condition. If you feel that your prescribed oxygen setting is no longer adequate, speak with your healthcare professional rather than changing the setting yourself.
Step 7: Connect the Nasal Cannula
After confirming oxygen is flowing from the outlet, connect the nasal cannula to the oxygen outlet.
Position the cannula so the prongs sit comfortably beneath your nose, with the tubing secured around your ears.
The tubing should remain free of:
- Kinks
- Twists
- Blockages
- Excessive bends
- Loose connections
A restricted oxygen tube can reduce airflow and prevent the equipment from operating as expected.
If you notice little or no airflow, check the tubing and connections before assuming there is a problem with the concentrator.
Step 8: Begin Your Prescribed Oxygen Therapy
Once the concentrator is running, the prescribed flow has been selected and the nasal cannula is positioned correctly, you can begin your oxygen therapy according to your healthcare professional's instructions.
Your treatment plan may specify:
- The oxygen flow rate
- How long to use supplemental oxygen
- When to use it
- Whether oxygen should be used continuously or during particular activities or periods
Follow your individualized treatment plan rather than using someone else's oxygen settings.
Step 9: Use the Timer Carefully
Some home oxygen concentrators include an automatic timer.
The VARON 105W Pro Wheel includes a timer that can be configured for automatic shutdown for up to eight hours. The timer can be adjusted in 10-minute increments.
To use the timer:
- Press Timing +.
- Change the display from "Running" to "Timing."
- Press Timing + to increase the shutdown time.
- Press Timing − to decrease the time.
- Stop pressing the buttons when the desired time is selected.
The concentrator will automatically shut down when the selected period ends.
However, people who require continuous oxygen should not use an automatic shutdown setting unless it is appropriate for their prescribed therapy.
Step 10: Finish Your Oxygen Therapy Safely
When your prescribed oxygen session is complete, turn off the oxygen concentrator correctly.
For the VARON 105W Pro Wheel:
- Press the ON/OFF button.
- Turn off the main power switch.
- Disconnect the power supply if appropriate.
If you need to temporarily stop oxygen delivery during operation, the ON/OFF control can be used to stop and restart the oxygen supply.
If restarting the machine after shutdown is necessary, allow at least 30 seconds before restarting.
