How Do You Breathe With an Oxygen Concentrator?

You breathe with an oxygen concentrator by receiving concentrated oxygen delivered through a nasal cannula or face mask.

Here's a breakdown of how the oxygen concentrator works and how you receive the oxygen:

• The Concentrator's Function: An oxygen concentrator doesn't supply oxygen from a tank; instead, it filters and concentrates oxygen from the surrounding air.

  • Air Intake: The machine draws in air from the room.
  • Filtration: The air passes through a series of filters to remove dust, allergens, and other impurities.
  • Nitrogen Removal: A specialized filter system removes nitrogen from the air. This system typically uses zeolite, a material that adsorbs nitrogen molecules.
  • Oxygen Concentration: After nitrogen removal, the remaining air is highly concentrated oxygen (typically 90-95%).
  • Oxygen Delivery: The concentrated oxygen is then delivered to you.

• Delivery Method: The oxygen is delivered through a tube connected to either:

  • Nasal Cannula: A lightweight tube with two prongs that fit just inside your nostrils. This is the most common delivery method.
  • Face Mask: A mask that covers your nose and mouth. This is used when a higher concentration of oxygen is needed or when a nasal cannula isn't suitable.

• Breathing Process:

  1. The oxygen concentrator is turned on and set to the prescribed flow rate (liters per minute, or LPM) by your doctor.
  2. You position the nasal cannula prongs in your nostrils or secure the face mask over your nose and mouth.
  3. You breathe normally through your nose or mouth. The concentrated oxygen mixes with the air you inhale.
  4. The increased oxygen concentration in your inhaled air helps to improve your blood oxygen levels.

• Important Considerations:

  • Prescription: You'll need a prescription from your doctor to get an oxygen concentrator and the proper flow rate setting.
  • Humidification: Sometimes, especially with higher flow rates, a humidifier bottle is attached to the concentrator to add moisture to the oxygen, preventing dryness of the nasal passages.
  • Maintenance: The concentrator needs regular maintenance, including cleaning or replacing filters.
  • Safety: Oxygen supports combustion, so keep the concentrator away from open flames, heat sources, and flammable materials. No smoking while using the device.

In summary, breathing with an oxygen concentrator involves using the device to filter and concentrate oxygen from the air, which is then delivered to you through a nasal cannula or mask as you breathe normally.
