How to Use an Oxygen Concentrator at Home (Step-by-Step Guide for Bangladesh – 2026)
Using an oxygen concentrator at home for the first time can feel a bit overwhelming.
You plug it in, turn it on—and then the questions start:
Is the flow correct? Is it working properly? Am I doing this safely?
If you’re in Bangladesh, there are a few extra things to think about too—like power issues, humidity, and dust.
This guide will walk you through everything step by step, in a simple and practical way, so you can use an oxygen concentrator confidently at home.
What You Need Before Starting
Before you switch on the machine, make sure you have:
- Oxygen concentrator unit
- Nasal cannula (oxygen tube)
- Humidifier bottle (if required)
- Clean water (boiled or distilled)

Step 1: Choose the Right Location
Where you place the machine matters more than most people think.
Do this:
- Keep 1–2 feet of space around the machine
- Place it in a well-ventilated room
- Keep it on a flat, stable surface
Avoid:
- Corners or tight spaces
- Near curtains or walls
- Damp or humid areas
Poor placement is one of the main reasons machines overheat.
Step 2: Set Up the Humidifier Bottle (If Needed)
If the oxygen flow is more than 2–3 LPM, a humidifier is usually required.
How to do it:
- Fill with boiled or distilled water
- Keep water between the min and max lines
- Attach the bottle securely
Never use raw tap water—it can damage the machine over time.
Step 3: Connect the Nasal Cannula
Attach the oxygen tube to:
- Humidifier outlet (if using bottle)
- Or directly to the machine outlet
Make sure:
- Connections are tight
- The tube is not bent or blocked
Step 4: Power On the Machine
Plug the concentrator directly into a wall socket.
Important tips (Bangladesh context):
- Avoid cheap extension cords
- Use a voltage stabilizer if needed
- Keep a backup ready for power cuts

Step 5: Set the Oxygen Flow Rate
This is the most critical step.
Turn the knob until the ball in the flow meter aligns with the prescribed level (LPM).
Important:
- Never increase the flow without a doctor’s advice
- Too much oxygen can be harmful
Step 6: Check if Oxygen is Flowing
To confirm the machine is working:
- Look at the flow meter (the ball should be steady)
- Feel airflow from the nasal tube
- Optional: dip tube in water—bubbles mean flow is active
Step 7: Place the Cannula Properly
Insert the nasal prongs into the nostrils and loop the tube behind the ears.
Make sure:
- It’s comfortable
- Not too tight
- The patient can breathe easily
Daily Usage Tips
- Use as prescribed by the doctor
- Keep the machine running in a stable environment
- Monitor patient condition regularly
