How to Prevent Dry Nose, Throat and Mouth Due to Oxygen Therapy

If you are using oxygen therapy for more than a few hours a day, one of the problems you might encounter is an uncomfortable, dry feeling in your throat, nose, or mouth. Many people deal with these issues when they first start using oxygen therapy, and they either get used to them, or they find a solution.

You don't need to deal with irritated skin or nose bleeds if you do a few simple things to prevent them. Simply keeping your oxygen concentrator, along with any accessories, properly clean can help remedy this problem.

When you first start using oxygen, the air flow may feel unusual. The feeling of using oxygen therapy is something that you will grow accustomed to over time.  It's important that you follow the flow rate prescribed by your doctor, do not lessen or increase your prescribed flow rate without consulting your physician. Remember, the most important part of oxygen therapy is getting your body the oxygen it needs!

Prevent Nose Bleeds

Nosebleeds can frequently happen for people using oxygen therapy. Nosebleeds often occur because the inside of your nostrils can dry out from the constant flow of air. The delicate skin inside your nose becomes irritated, and one little bump with the edge of the nasal cannula is enough to cause a tiny break in the skin. Bloody noses also happen if you are using a high flow of oxygen through a face mask instead of a cannula. Another normal occurrence is seeing blood in your mucus after you blow your nose while using your oxygen concentrator.

Educate yourself with our Free Oxygen Therapy Guide

To prevent bloody noses and dry nasal skin in general, you can use a moisturizing balm. There are moisturizing balms on the market that are specifically made for dry nasal passages due to oxygen therapy, but you can also use sesame seed oil for the same effect. Sesame seed oil is a natural anti-inflammatory, and can also protect you from germs that might be hiding in your nose. Apply the moisturizing balm or sesame seed oil to the inside of your nostrils with the tip of a cotton swab, or with a clean finger. A thin coating is enough, you don't want to apply too much, or it may be uncomfortable.

Add Humidity

Dry nose and throat can often be treated and prevented by using a humidifier bottle with your oxygen concentrator. These particular bottles attach to your concentrator and force the oxygen through water. This process helps to add moisture into the oxygen provided to you so that it will not dry you out nearly as much.

If you are experiencing a dry mouth and throat while using a humidifier bottle, you can use a room humidifier to add even more moisture to the air you're breathing in. You might find that you need this the most while you are sleeping when we tend to breathe through our mouths more. Make sure the water that you are using in your humidifiers is distilled.

Keep it Clean

Wash out your humidifier, as well as the rubber tubing and nasal cannula, with a mild detergent and water once a week. You will need to replace your tubing every couple months and your nasal cannula at least once per month.

As always, make sure to speak to your physician if you have any questions or concerns regarding your condition and your treatment. Following these simple steps can help reduce dryness that can come when using oxygen therapy.

    What about a dry throat? My brother had throat surgery a few years ago and they have put him on 24 hour Oxygen. It drys his throat out.

    I've been on O2 therapy at night while I sleep for about 10 months now. I have had nosebleeds and now I've noticed that I have a small (feels bigger than it is, I'm sure, since it's inside my nose). It gets dry and if I blow my nose, it will bleed. Idk what a humidifier for it would look like and my Pulmonologist wanted me to call he equipment company n tell them that he wants it added, but they won't call me back. What do I do?

    I am on oxygen everyday all day long lately I have been having nose bleeds I am going to try the sesame seed oil I hope it works

  • ccanady

    I didn't get a nose bleed until the provider was changed, I want my old one back. The humidifier on the
    unit does not work for me. My doctor suggested Vaseline and it helps some. The nasal cannula that goes in the nose is to long, so I cut it to make shorter and that has helped.

    I am trying to find something to help with my nose bleed

    How about grape seed oil for dry nostrils

    • Danielle Jason

      Thank you for your inquiry, Mark. We suggest consulting your doctor as we are unsure if grape seed oil would have the same effects as sesame seed oil. Have you tried the sesame oil alternative?

  • Doug

    Can I use Afrin nasal spray if I’m on oxygen at night?

      Thank you for your inquiry, Doug. As far as your oxygen concentrator is concerned there is no issue with using a nasal spray. We do however recommend that you consult with your doctor first before using any medications that you have not already discussed with your doctor.

      Frozen vasiline is great for nose bleeds

  • Carla Fisher

    I've read that vaseline and petroleum based things should not be used on your face with oxygen - safety. I am going to try sesame oil - smelling like Chinese food is ok! I also get some relief with a cotton swab wet with water - but it's temporary.

    I hope this will help someone. My cannula prongs were too long and especially while I slept the prongs would go so deep in my nose it was clogging the prong up from pressing into the back wall of my nasal cavity. It was also clogging my nose up because the prongs were plugging up the back of my nose. I would wake up feeling like I was suffocating. What I done is to ask my provider to let me try pediatric size cannula. While its not a 100% fix the difference in the oxygen I'm getting through my nose has improved significantly. Hugs to all.

    I am on oxygen therapy 24 hrs a day. The mucus my nasal passages dry and blocks the nasal passage making it even more difficult to breath.
    This a chronic problem. I would love some advise.

      You might want to try a daily nasal rinse in the morning and see if that helps. You should also talk with your doctor if this is something that is preventing your oxygen levels from staying where they need to be.

    I have a couple questions -

    1. The homecare company I’m with said there’s no such thing as a “humidifier” for the oxygen concentrated I have. Besides using diffusers with water and essential oils is there any way to make more moisture in the air?

    2. At night I always pull my cannula off while asleep. I’ve tried a small bit of paper tape and other adhesives I’m not allergic to but I still manage to pull it off. I have continuous flow of oxygen day and night but for whatever reason I can’t seem to get through a night without pulling it off.

    3. The dryness that everyone has. I try oil every day and night but still get a dry nose throat and mouth. I have other factors contributing to this as well, but sometimes I get a very sharp and cold pain going up my nasal passage up to my eyebrows. Does anyone else have this? Is this common with patients on oxygen?
    Thank you so much

      1. You can look into getting a room or home humidifier.
      2. In addition to using tape, you might want to try tightening the cannula around your neck with the fastener.
      3. It seems that a lot of patients have dryness. If you feel that something is wrong consult with your doctor about additional possible solutions.
