How to Keep an Oxygen Tube in Your Nose

A nasal cannula stays put when three things work together: the prongs sit correctly inside the nostrils, the tubing is routed and secured so everyday movement does not dislodge it, and the skin underneath stays healthy enough that you are not constantly readjusting out of discomfort. Most people who struggle with a cannula that keeps slipping or falling out can fix the problem with a few simple adjustments to fit, taping technique, and moisture management. The specifics matter more than you might expect, and small changes often make the difference between an oxygen tube that cooperates and one that fights you all day.

Getting the Fit Right From the Start

The most common reason a nasal cannula will not stay in place is that the initial setup is slightly off. Nasal cannula prongs are curved, and those curves need to point downward, following the natural angle of your nostrils. If the prongs point straight in or, worse, upward, they will irritate the septum and gradually work their way out. Gently insert the prongs so they rest just inside the nostril opening without pushing deep. You should feel the prongs lightly touching the inside of your nose, not pressing hard against the tissue.

Once the prongs are seated, drape the tubing over both ears, running it along your cheeks and under your chin. The small plastic slider under your chin is there to snug the tubing against your face. Pull it up until the cannula feels secure but not tight. A common mistake is cranking the slider too far up, which creates pressure on the ears and the base of the nose. You want just enough tension that the tubing does not swing freely when you turn your head. If the cannula still slides around after adjusting the slider, the issue is usually the tubing catching on clothing or furniture rather than the fit itself.

Cannulas come in different sizes, and not every one fits every nose. If you have smaller nostrils and the standard adult prongs feel bulky or keep popping out, ask your supplier about a smaller-prong option. Pediatric-sized prongs sometimes work well for adults with narrow nasal passages. Conversely, if the prongs seem to disappear entirely inside your nose without making contact, a slightly larger cannula will sit more securely.

Taping and Securing the Cannula to Your Face

When proper fit alone is not enough, medical tape becomes your best friend. The goal is to anchor the tubing to your cheeks so the cannula stays in position even if the tubing behind your ears gets tugged. Use a short strip of hypoallergenic medical tape on each cheek, pressing the tubing flat against the skin just below the cheekbone. Paper tape, silk tape, and foam tape all work. The key is choosing a tape that sticks well enough to hold through a few hours but releases without tearing your skin when you need to remove it.

If you have sensitive skin or find that tape leaves red marks, look for silicone-based adhesive strips. These grip gently, peel off without pulling on the skin, and can often be repositioned a few times before losing their stickiness. Some people also use liquid skin barrier wipes or sprays before applying tape. These leave a thin protective film on the skin that helps tape adhere better and reduces irritation when the tape comes off. A barrier wipe is especially useful if you sweat, because perspiration is the main reason tape loosens during the day.

A few practical tips for taping: always apply tape to clean, dry skin. Oils, moisturizers, and sweat all defeat adhesive. If you use a facial moisturizer, keep it away from the areas where you plan to tape. Replace the tape when it starts to curl at the edges or lose grip rather than pressing it down harder, because a half-stuck strip just creates more friction on the skin. And rotate the exact spot where you tape by a centimeter or so each day to give the skin underneath a break.

Protecting Your Skin From Pressure Injuries

A nasal cannula is a medical device pressed against your face for hours at a time, and that sustained contact can cause pressure injuries. These show up as red marks, sore spots, or even shallow wounds on the bridge of the nose, behind the ears, and along the cheeks where the tubing rests. The injuries take the same shape as the device causing them, so a cannula-related sore will often follow the line of the tubing or the outline of a prong.

An expert panel reviewing evidence on device-related pressure injuries recommended placing thin dressings that redistribute pressure and absorb moisture between the skin and any medical device that rests against the body. They also stressed the importance of regularly lifting or shifting the device to inspect the skin underneath and relieve pressure. One critical caveat: if the device already fits tightly, adding a dressing underneath can actually increase pressure rather than relieve it, making things worse.¹

In practice, this means thin foam or hydrocolloid dressing strips placed over the tops of the ears or along the bridge of the nose can cushion the tubing. Many oxygen users cut small pieces of foam dressing and stick them behind each ear where the tubing drapes over. You can also find pre-made ear cushion pads designed specifically for cannula tubing, which are essentially the same idea in a more convenient shape. Whatever you use, lift the cannula at least every couple of hours to check for redness. If you notice a mark forming, shift the tubing to a slightly different position.

Dealing With Nasal Dryness and Irritation

Even when a cannula fits perfectly and stays in place, the dryness it causes can make you want to pull it out. Supplemental oxygen, especially at flow rates above a couple of liters per minute, dries out the nasal passages. A prospective study of patients receiving oxygen by nasal cannula found that dry nose and dry throat were the most frequently reported complaints, showing up in roughly 43 percent of daily patient interviews. The symptoms were relatively mild in most cases and did not worsen significantly when the oxygen lacked added humidification, but over days and weeks, even mild dryness becomes a persistent annoyance that makes keeping the cannula in harder.²

If your oxygen concentrator or tank has a humidifier bottle attachment, use it. The bottle adds moisture to the oxygen before it reaches your nose. Keep the water level topped up and change the water daily to prevent bacterial growth. For people on higher flow rates, heated humidified systems make an even bigger difference. Research on high-flow nasal cannula systems has shown that heating and humidifying the delivered gas enhances patient comfort and tolerance compared with unhumidified high-flow setups.³

Humidity levels matter in a measurable way. A bench and clinical study of high-flow cannula devices found that breathing comfort dropped significantly when the absolute humidity of the delivered gas fell from higher levels to lower levels, with patients rating their comfort roughly half as good at lower humidity settings. Comfort leveled off once the humidity reached a moderate threshold, meaning there is a sweet spot rather than a “more is always better” relationship.⁴

Beyond the humidifier, water-based nasal saline sprays or gels applied a few times a day help keep the nasal lining moist. Avoid petroleum-based products like plain Vaseline inside the nose if you are on supplemental oxygen, because petroleum jelly and pure oxygen together create a fire risk. Water-based or saline-based products are safe alternatives. Some people find that a room humidifier running near their bed at night also reduces nasal dryness, complementing whatever the oxygen system’s humidifier is doing.

Keeping the Cannula in Place While Sleeping

Nighttime is when most people lose their cannula. You roll over, your hand brushes your face, the tubing catches on a pillow, and by morning the prongs are somewhere near your ear instead of your nose. A few strategies can cut down on this.

First, give yourself enough tubing slack between the oxygen source and your bed so that rolling over does not create a pulling force on the cannula. If the tubing is taut when you face one direction, every turn in your sleep will yank the prongs. Running the tubing up through your shirt collar or clipping it to your pajama top near the shoulder takes the tension off your face and transfers it to your clothing, so your head can move more freely without disturbing the cannula.

Second, tape the cannula to your cheeks before bed. Daytime, you might get away with just the chin slider, but at night the extra security of two small tape strips makes a real difference. Some people add a third strip across the bridge of the nose for particularly restless sleepers, though this increases the risk of skin irritation if done every night, so rotating between taping strategies helps.

Third, consider a cannula headband or soft strap that wraps around the back of the head and holds the tubing in place without relying on the ears. These are widely available from medical supply retailers and take the tubing off the ears entirely, which also helps if ear soreness has been a problem. The headband approach is especially useful for side sleepers, because the tubing is not pressed between your ear and the pillow.

If you use a CPAP or BiPAP machine in addition to supplemental oxygen, talk to your respiratory therapist about integrated setups. Oxygen can often be bled into the CPAP circuit, eliminating the need for a separate nasal cannula at night altogether.

Staying Active Without Losing the Tube

Moving around the house, going for walks, or doing light exercise with a nasal cannula requires managing the tubing so it does not snag on doorknobs, furniture, or your own arms. The simplest fix is a tubing clip that attaches the oxygen line to your shirt at the collar or shoulder. This keeps the tubing running along your body rather than swinging freely, and it absorbs sudden tugs before they reach the cannula on your face.

For longer walks or outings, a portable oxygen concentrator with a shorter cannula line reduces the amount of tubing you are managing. If you are using a traditional tank with a long hose, coil the excess and tuck it into a pocket or a small pouch attached to your tank cart. The less loose tubing hanging around, the fewer chances it has to catch on something.

Sweat during physical activity loosens tape and makes skin slippery, so the cannula is more likely to shift. If you exercise regularly, consider the silicone-based adhesive strips mentioned earlier, which tolerate moisture better than paper tape. Applying a skin barrier wipe before taping adds another layer of sweat resistance. And if you are doing anything vigorous enough that the cannula simply will not stay put, ask your provider whether a nasal mask or oxygen-conserving device might work better for exercise sessions specifically.

When Ear Pain Becomes the Real Problem

For many long-term oxygen users, the cannula staying in the nose is less of an issue than the pain it causes behind the ears. The tubing loops over the ears and sits in the crease behind them for hours, and that constant pressure causes soreness, chafing, and sometimes even open wounds. The discomfort eventually gets bad enough that people take the cannula off just to give their ears a break, defeating the purpose.

Foam tubing covers are the most common solution. These are soft, cylindrical pieces of foam that slide over the section of tubing that rests on the ears, spreading the pressure over a wider area. You can buy them pre-made or simply cut pieces from soft foam tubing available at hardware stores. Some people use adhesive moleskin or felt pads placed directly on the skin behind the ear as an alternative. The principle behind all of these is the same as the dressing recommendation for device-related pressure injuries: redistribute the pressure and cushion the contact point.¹

Another option is to bypass the ears entirely. Over-the-head strap systems and behind-the-head cannula holders route the tubing across the top or back of the head instead of over the ears. These are particularly popular with people who wear glasses or hearing aids, because the ears are already crowded real estate. Some people fashion their own version with a soft headband and a couple of small clips. The tradeoff is that head-strap systems can feel bulkier and more noticeable, which matters to some people and not at all to others.

Common Mistakes That Make Everything Harder

A few patterns come up repeatedly among people who struggle with keeping a nasal cannula in place, and most are easy to fix once you know about them.

Tubing too short: If the line from your oxygen source to your face is barely long enough, every step you take or turn of your head creates tension that pulls the prongs out. Use enough tubing length to move freely around your primary living space, and add extension tubing if needed rather than straining the connection.
Wrong prong angle: Inserting the prongs so they curve upward or sideways instead of downward irritates the inside of the nose and causes the cannula to creep out over time. Check the prong direction every time you put the cannula on.
Ignoring skin breakdown: Powering through sore spots leads to wounds that then make wearing the cannula even more painful. Catching redness early and cushioning or repositioning before it becomes an open sore saves you weeks of discomfort.
Skipping humidification: Dry, cracked nasal passages make the prongs feel abrasive, and you end up removing the cannula more often for relief. Keeping the nasal lining moist directly improves your ability to tolerate the device for longer stretches.
Over-tightening the chin slider: Cranking the slider up until the tubing is tight against your face seems like it would help, but it increases pressure on the ears and nose, causes more skin problems, and paradoxically makes you want to remove the cannula sooner.

Talking to Your Respiratory Therapist About Alternatives

If you have tried all the fit, taping, and comfort strategies and still cannot keep a standard nasal cannula in place, it is worth having a conversation with your respiratory therapist or pulmonologist about alternatives. Some options include oxygen-conserving devices, which deliver a pulse of oxygen only when you inhale rather than flowing continuously. Because the flow is intermittent, these systems sometimes use softer, smaller cannulas that sit more comfortably. Transtracheal oxygen delivery, where a small catheter is placed directly into the trachea through a minor procedure, eliminates the nasal cannula entirely and is sometimes used for people who need high flow rates or cannot tolerate nasal delivery at all.

For people who mainly struggle at night, a nasal pillow mask, similar to those used with CPAP machines, holds itself in place with a headgear strap and seals around the nostrils rather than inserting prongs into them. These are not standard for plain supplemental oxygen but can sometimes be adapted for that purpose. The point is that the standard two-prong nasal cannula is the default, not the only possibility. If it is genuinely not working for your anatomy or your lifestyle, your care team has other tools available, and asking about them is reasonable, not a sign that you are doing something wrong.
