Using an oxygen concentrator at home can be life-changing for patients who struggle with breathing problems. However, for first-time users and caregivers, operating the machine correctly can feel confusing and even overwhelming. Questions like how to use an oxygen concentrator, whether it is safe for long hours, or why the oxygen machine is beeping are very common.

This beginner’s guide is designed to help you understand how to use an oxygen concentrator at home safely, step by step. Whether the equipment is recommended after hospital discharge or for long-term respiratory support, knowing the correct usage, safety precautions, and maintenance will ensure better comfort and peace of mind for both patients and caregivers.

What Is an Oxygen Concentrator?

An oxygen concentrator is a medical device that provides supplemental oxygen to patients who have difficulty breathing on their own. Unlike oxygen cylinders that store oxygen, an oxygen concentrator draws in air from the surroundings, removes nitrogen, and delivers purified oxygen to the patient.

Oxygen concentrators are commonly used for

• Chronic Obstructive Pulmonary Disease (COPD)
• Post-COVID respiratory recovery
• Asthma and lung infections
• Elderly patients with low oxygen saturation
• Long-term oxygen therapy at home
  
  

Because it provides a continuous supply of oxygen, an oxygen concentrator is often preferred for home use compared to cylinders.

How Does an Oxygen Concentrator Work?

Understanding how an oxygen concentrator works helps users operate it with confidence.

The machine pulls in normal air from the room, which contains around 21% oxygen. Inside the concentrator, filters and sieve beds separate nitrogen from the air. The remaining oxygen—usually concentrated up to 90–95% purity—is delivered to the patient through a nasal cannula or oxygen mask.

Most oxygen concentrators run on electricity and are designed for continuous operation, making them suitable for oxygen therapy at home.

How to Use an Oxygen Concentrator at Home (Step-by-Step)

 

This is the most important section for first-time users. Follow these steps carefully to ensure safe and effective oxygen delivery.

Step 1: Choose the Right Place at Home

Place the oxygen concentrator in

• A well-ventilated area
• At least 1–2 feet away from walls or furniture
• A dry and dust-free environment
  
  

Avoid placing the machine near curtains, beds, or heat sources. Proper airflow is essential for the concentrator to function efficiently.

Step 2: Connect the Accessories Properly

Before switching on the machine

• Attach the oxygen tubing firmly to the outlet
• Connect the nasal cannula or oxygen mask
  
• If prescribed, fill the humidifier bottle with clean distilled water and attach it correctly
  
  

Ensure there are no bends or kinks in the tubing, as this can restrict oxygen flow.

Step 3: Set the Prescribed Oxygen Flow

Always follow the doctor’s prescription for oxygen flow rate (measured in litres per minute).

• Use the flow meter knob to set the recommended level
• Never increase or decrease oxygen flow without medical advice
• Excess oxygen can be harmful, especially for long-term users
  
  

This step is crucial when learning how to operate an oxygen concentrator safely.

Step 4: Start the Oxygen Concentrator

Once everything is connected

• Switch on the power button
• Allow the machine a few seconds to stabilize
• Check that oxygen is flowing through the cannula or mask
  
  

Ensure the patient is comfortable and breathing normally.

Step 5: Monitor the Patient During Use

While the oxygen concentrator is in use

• Observe breathing patterns
• Check oxygen saturation levels if a pulse oximeter is available
• Look out for discomfort, dryness, or irritation
  
  

If the patient feels dizzy, uncomfortable, or short of breath, stop the machine and contact a healthcare professional immediately.

Safety Tips While Using an Oxygen Concentrator at Home

Using an oxygen concentrator at home is generally safe when proper precautions are followed.

Important safety tips

• No smoking or open flames near the machine
• Keep away from gas stoves and candles
• Ensure proper electrical grounding
• Do not use extension cords unless recommended
• Keep the machine clean and dry
  
  

Following these guidelines helps prevent accidents and ensures safe oxygen therapy at home.

Why Is My Oxygen Concentrator Beeping?

A beeping oxygen machine can cause panic, but it usually indicates a common issue.

Possible reasons include

• Power interruption or loose plug
• Blocked or dirty filter
• Kinked oxygen tubing
• Low oxygen purity
• Overheating due to poor ventilation
  
  

What to do

• Check the power supply
• Straighten the tubing
• Clean or replace filters if needed
• Ensure proper airflow around the machine
  
  

If the beeping continues, contact technical support instead of attempting repairs yourself.

How to Clean and Maintain an Oxygen Concentrator

 

Proper cleaning and maintenance improve performance and extend the machine’s life.

Cleaning the Oxygen Concentrator Filter

• Remove the filter as per the manufacturer's instructions
• Wash with mild soap and clean water
• Allow it to dry completely before reinserting
• Clean filters at least once a week or as advised
  
  

General Maintenance Tips

• Wipe the exterior regularly
• Keep vents dust-free
• Check tubing and accessories for wear
• Schedule professional servicing periodically
  
  

Regular maintenance ensures safe and uninterrupted oxygen delivery.

Oxygen Concentrator for Home Use – Price & Availability

The price of an oxygen concentrator for home use depends on

• Oxygen flow capacity (5L, 10L, etc.)
• Brand and features
• Portability and noise levels
  
  

Many families choose oxygen concentrator rental instead of purchasing, especially for short-term medical needs. Renting reduces costs and includes service support, making it a practical solution for home care.

When Should You Choose Professional Support?

Using an oxygen concentrator becomes easier with proper guidance, especially for

• First-time users
• Elderly or critical patients
• Long-term oxygen therapy
  
  

Professional healthcare providers like Enshrine Healthcare Systems offer oxygen concentrators for home use with proper installation, demonstration, and ongoing support. This ensures patients receive oxygen therapy safely and caregivers feel confident managing the equipment at home.
