Q. I use oxygen when I sleep and want to keep my Inogen G5 outside the bedroom since it's noisy. What's the maximum cannula length that will still work- would a 50 ft tube be okay, or should I stick with 25ft? 

 

A. According to Inogen’s official guidelines, the maximum recommended nasal cannula length for the Inogen One G5 is 25 feet. This includes the standard 7-foot cannula plus up to 15 feet of extension tubing. Using tubing longer than 25 feet may result in reduced oxygen delivery and impaired pulse dose detection, especially during sleep when breathing is shallower. If you place the G5 outside your bedroom, ensure the total tubing length does not exceed 25 feet.

Q. I have a 50- foot hose coming out of the concentrator, how often should I replace it?

 

A. For optimal safety and performance, oxygen supply tubing—regardless of length—should be replaced every six (6) months.

However, if you use oxygen continuously or for many hours daily, or if the tubing is exposed to heat, sunlight, or humidity, you may need to replace it more frequently—every three (3) months.

Replace tubing immediately if you notice:

  • Discoloration (yellowing or cloudiness)
  • Stiffness or brittleness
  • Cracks, kinks, or leaks
  • Reduced oxygen flow
  • Visible contamination or buildup

Longer tubing (like 50 feet) may be more prone to wear and flow resistance, so regular inspection is especially important.

Note: Nasal cannulas should generally be replaced at least once (1) a month for regular use (or immediately after illness or when visibly soiled, discolored, or causing irritation).

Q. How do I properly clean my Oxygen or CPAP machine?

 

A. 

For CPAP Machines:

Daily Cleaning:

  • Mask & Nasal Pillows: Wash with warm water and mild, fragrance-free soap. Rinse thoroughly and air dry on a clean towel.
  • Humidifier Chamber: Empty water daily. Rinse with warm water and let air dry upside down.
  • Headgear: Wipe with a damp cloth and mild soap. Air dry completely.

Weekly Cleaning:

  • Tubing: Soak in warm, soapy water or a vinegar solution (1 part white vinegar to 3 parts water). Rinse thoroughly and hang to dry vertically.
  • Humidifier Chamber: Deep clean with soap or vinegar solution. Rinse and air dry.
  • Reusable Filters: Rinse with water (if washable) and let air dry. Replace monthly or every 6 months per manufacturer instructions. (Disposable filters should replace monthly or sooner if needed).
  • Machine Exterior: Wipe with a damp cloth. Never submerge the machine or use harsh cleaners.

Always unplug the CPAP machine before cleaning. Never use bleach, alcohol, or scented soaps.

 

For Oxygen Concentrators:

Weekly to Monthly Cleaning:

  • Exterior: Wipe down with a soft, damp cloth. Avoid harsh chemicals or submerging the unit.
  • Filters:
    • External foam filters: Wash weekly with warm water and mild soap. Air dry completely before reinserting.
  • Tubing & Cannula:
    • Cannula: Replace once a month.
    • Tubing: Replace every 6 months, or immediately if discolored, stiff, or cracked.

Never clean the concentrator while it’s running. Use only manufacturer-approved parts and cleaning methods

Q. My nose feels dry and irritated from the oxygen. What can I do to relieve this?

 

A. Dryness and irritation in the nose are common side effects of oxygen therapy, especially when using nasal cannulas. Here are clinically recommended strategies to relieve and prevent this discomfort:

1. Use a Humidifier

  • Attach a humidifier bottle to your oxygen concentrator if compatible. This adds moisture to the oxygen and reduces nasal dryness.
  • Alternatively, use a room humidifier to increase ambient humidity, especially during sleep.

2. Apply Nasal Moisturizers

  • Use water-based nasal gels or sprays such as:
    • Ayr Saline Nasal Gel
    • Cann-Ease Nasal Moisturizer
    • RoEzIt Dermal Care
  • Avoid petroleum-based products (e.g., Vaseline), which can pose a fire risk and burning when used with oxygen.

3. Switch to Soft-Touch Cannulas

  • Soft-touch or silicone nasal cannulas are gentler on the skin and reduce irritation from friction.

4. Clean and Replace Equipment Regularly

  • Wash nasal prongs weekly with mild soap and water.
  • Replace nasal cannulas once a month, or sooner if they become stiff, discolored, or uncomfortable.

5. Stay Hydrated

  • Drink plenty of water throughout the day to help keep mucous membranes moist.

6. Consult Your Provider

If dryness persists or leads to nosebleeds or sores, speak with your healthcare provider.
