Keeping a nasal cannula in place requires attention to fit, the right accessories, and care for the skin underneath. About a third of long-term oxygen therapy users experience the cannula slipping off at least once a week, and the consequences go beyond annoyance. The fix is rarely a single trick; it usually involves a combination of proper sizing, strategic taping or securement devices, skin protection, and managing the discomfort that makes people pull the cannula off in the first place.
Why Dislodgement Matters More Than Annoyance
A nasal cannula that slips off repeatedly is not just inconvenient. In a study of veterans on long-term oxygen therapy, those who experienced weekly dislodgement were hospitalized for COPD flare-ups at more than twice the rate of those whose cannulas stayed put, and their overall hospital costs were about 25% higher.1Federal Practitioner. Nasal Cannula Dislodgement During Sleep in Veterans Receiving Long-term Oxygen Therapy for Hypoxemic Chronic Respiratory Failure Those numbers make sense when you consider that every hour without supplemental oxygen can push blood oxygen levels into a range that strains the heart and lungs. Fixing the problem is not a matter of vanity or convenience; it directly affects health outcomes.
Getting the Basic Fit Right
Before reaching for tape or accessories, make sure the cannula itself fits properly. The two prongs should curve gently downward into the nostrils, not push upward or sideways. If the prongs are too long, they press uncomfortably against the nasal septum and the wearer instinctively tugs at them. If they’re too short or too narrow, they sit loosely and fall out at the slightest head movement.
Cannulas come in different sizes for adults, and the tubing diameter varies between standard low-flow models and high-flow systems. If you’ve been handed a one-size-fits-all cannula from a supplier and it doesn’t feel right, ask your respiratory therapist or home health provider about sizing options. Some manufacturers offer small-adult and large-adult versions, as well as models with softer, more flexible prongs. A cannula that fits well from the start needs far less tape and fewer accessories to stay in place.
When placing the cannula, loop the tubing over your ears and then snug the slide adjuster under your chin. The tubing should rest against your cheeks without pulling. If it drags or catches on your collar, the tension eventually works the prongs loose. Route the excess tubing behind you or clip it to your clothing near the shoulder so the weight of the line doesn’t tug on the cannula throughout the day.
Taping and Fixation Strips
Medical tape across the cheeks is one of the oldest solutions, and it works. The key is technique. A strip of hypoallergenic tape on each cheek, angled so it anchors both the tubing and the slide adjuster, holds the cannula far more securely than a single horizontal strip across the upper lip. For people who need a more formal fixation approach, modified pressure-reducing fixation strips designed specifically for nasal cannula tubing have shown real benefits. In a study of patients on high-flow nasal cannula therapy, those using a modified protective nasal strip went significantly longer between fixation changes and needed fewer position adjustments compared to patients using standard securement methods.2PubMed Central.

If you’re taping at home, a few practical points help. Use paper or silicone-based medical tape rather than standard adhesive tape, which can irritate the skin within hours. Replace the tape at least daily and gently clean the skin underneath with a damp cloth before reapplying. Avoid taping directly over bony prominences or areas that are already red. And never tape so tightly that the prongs press hard into the nostrils; the goal is to keep the tubing from shifting, not to force the prongs deeper.
Accessories for Extra Security
Tape isn’t the only option. A range of over-the-counter accessories exists specifically for nasal cannula users, and mixing and matching often works better than relying on a single product.
- Ear cushions: Soft foam or silicone pads that slip over the tubing where it loops behind the ears. They don’t hold the cannula in place by themselves, but they eliminate the rubbing and soreness that makes people remove the cannula, which is the most common reason for dislodgement during the day.
- Headbands and head straps: Fabric bands that wrap around the head and hold the cannula tubing against the temples and behind the ears. These are especially useful at night when chin movement and pillow friction can dislodge the tubing.
- Adhesive cheek tabs: Small sticky pads that attach to the cheeks and grip the tubing. They serve the same role as tape but are designed for easy removal and reapplication, making them gentler on the skin over time.
- Chin straps: Straps that pass under the chin and connect to the cannula tubing on both sides. They prevent the slide adjuster from loosening and keep the tubing from riding up off the ears during sleep.
None of these accessories are expensive, and most are available online or through durable medical equipment suppliers. If cost is a concern, ear cushions alone often make the biggest single difference. Research into what drives oxygen therapy compliance consistently finds that device comfort is one of the top factors determining whether people actually keep their cannula on.3PubMed.

The Nighttime Problem
Sleep is when most dislodgement happens. You roll over, your face presses into a pillow, and the tubing catches on fabric or gets pinched under your shoulder. By morning the cannula is on the floor and your oxygen saturation has been dropping for hours without your knowledge. In the veteran study mentioned earlier, the median frequency among those who experienced regular nighttime dislodgement was four times per week.1Federal Practitioner. Nasal Cannula Dislodgement During Sleep in Veterans Receiving Long-term Oxygen Therapy for Hypoxemic Chronic Respiratory Failure
A few adjustments can help. Sleeping on your back keeps the cannula away from pillow friction, though that’s not realistic for everyone. Side sleepers can benefit from a contoured pillow with a cutout near the face, which gives the tubing room to sit without getting crushed. Routing the tubing over the top of your head and down the back rather than over the ears eliminates one of the main snag points. A chin strap or a soft headband worn at night adds redundancy so that even if one anchor point shifts, another keeps the cannula roughly in position.
Some people clip a pulse oximeter with an alarm to their finger overnight. If oxygen levels drop below a set threshold, the alarm wakes them to reposition the cannula. This doesn’t prevent dislodgement, but it limits how long you go without oxygen when it does happen.
Protecting Your Skin From Pressure and Friction
The cannula presses against the nose, the upper lip, the cheeks, and the tops of the ears for hours on end. Pressure injuries in those areas are common, and once the skin breaks down, wearing the cannula becomes painful enough that people stop using it altogether. This is a well-documented issue in hospitals, particularly in intensive care and neonatal units where patients wear cannulas continuously.
Hydrocolloid dressings, the thin gel-like patches used in wound care, provide a protective barrier between the device and the skin. In a randomized trial of preterm infants on nasal continuous positive airway pressure, those fitted with a protective dressing over the nose developed injuries at a dramatically lower rate compared to those without one.4Advances in Skin & Wound Care. Protective Dressings, Injury, and Device Failure in Preterm Infants Receiving Nasal Continuous Positive Airway Pressure: A Randomized Controlled Trial Similar findings have been reported in separate studies, with hydrocolloid application significantly reducing both the frequency and severity of nasal injury.5PubMed Central. Hydrocolloid dressing in preventing nasal trauma secondary to nasal continuous positive airway pressure in preterm infants While these studies focused on neonatal patients, the principle applies to adults: a thin barrier dressing between the cannula and the skin reduces friction and distributes pressure.
The ears deserve attention too. One hospital quality-improvement project found that switching to soft silicone nasal cannulas eliminated cannula-related pressure ulcers entirely over a nearly two-year period, while also saving money previously spent on foam padding and nursing time.6WOCN Society. No More Sore Ears: Nasal Cannula Related Pressure Ulcers Down to Zero If your ears are getting sore and you’re currently using a standard PVC cannula, ask your provider about softer materials. For an immediate fix, foam ear cushions or small pieces of moleskin behind the ears can bridge the gap.
Keeping Nasal Passages Comfortable
Dry, cracked nasal passages are one of the most underappreciated reasons cannulas don’t stay put. When the inside of your nose is raw and sore, you instinctively shift or remove the cannula because the prongs feel like they’re burning. Low-flow oxygen delivered through a nasal cannula is typically dry, and over hours it pulls moisture from the nasal mucosa. A humidifier bottle attached to the oxygen source helps, but many home oxygen setups omit it at lower flow rates.
If your nose is drying out, a water-based nasal saline spray or gel applied to the nostrils a few times a day can make a real difference. What you should not use is petroleum jelly or any oil-based product. Petroleum-based products are a recognized safety concern around supplemental oxygen because of their potential to support combustion near oxygen-enriched environments. Pharmacists and safety guidelines recommend water-based moisturizers or oil-in-water creams whenever lubrication is needed for patients on oxygen therapy.7PubMed. Safety in the use of vaseline during oxygen therapy: the pharmacist’s perspective Water-based nasal gels designed for oxygen users are widely available at pharmacies and online.
If dryness remains a problem even with saline spray, talk to your provider about adding a humidifier bottle to your oxygen concentrator or tank setup. The additional moisture in the delivered gas reduces mucosal drying at the source and can make wearing the cannula for extended periods far more tolerable.
When a Standard Cannula Keeps Failing
Some people do everything right and the cannula still won’t stay put or won’t deliver oxygen effectively. This is sometimes an anatomy issue rather than a technique problem. A deviated nasal septum or nasal polyps can obstruct airflow through one or both nostrils, meaning the prongs can’t sit properly and the oxygen delivery is inefficient regardless of securement.8European Respiratory Society. Oxygen devices and delivery systems If you find yourself constantly adjusting the prongs or feeling like you’re not getting enough air despite a properly flowing oxygen source, bring this up with your doctor. A quick examination can identify structural issues that no amount of tape will fix.
Alternative delivery interfaces exist for people who genuinely can’t manage a nasal cannula. A simple oxygen mask covers the nose and mouth and doesn’t depend on nasal anatomy at all, though it’s bulkier and makes eating and talking harder. Reservoir masks deliver higher oxygen concentrations for people who need them. For patients who primarily struggle at night, some providers prescribe a nasal cannula for daytime use and a different interface for sleep. The conversation with your respiratory therapist or pulmonologist is worth having if you’ve tried the securement strategies above and still experience frequent dislodgement.
Helping Someone With Cognitive Decline
Keeping a nasal cannula on a person with dementia or delirium is one of the most challenging situations caregivers face. The person may not understand why the device is there and will repeatedly pull it off. Restraining someone’s hands is a last resort and raises serious ethical and safety concerns. Practical strategies tend to work better than force.
Comfort is the starting point. If the cannula irritates the skin or the nose, a person with cognitive impairment will remove it even more quickly than someone who can rationalize the discomfort. Ear cushions, soft silicone tubing, and a well-humidified oxygen source reduce the sensory triggers that prompt removal. Routing the tubing over the top of the head or behind the back and out of the person’s line of sight can help, since many patients pull at what they can see and feel on their face.
A chin strap or headband provides a secondary anchor that slows down removal even when the person does reach for the cannula. Some caregivers find that loosely fitting cotton gloves or hand mitts reduce the dexterity needed to pull off tubing without fully restraining the hands. Timing matters too: if the person is more agitated in the afternoon or evening, coordinating oxygen delivery around calmer periods can increase the total hours of effective therapy even if 24-hour compliance isn’t achievable.
When none of these strategies keep the cannula on for meaningful periods, it’s worth discussing the goals of oxygen therapy with the medical team. In some late-stage situations, the distress caused by repeated cannula replacement may outweigh the benefit of supplemental oxygen, and comfort-focused care may take priority. That is a conversation between the care team, the patient’s family, and ideally a palliative care specialist rather than something to decide alone at home.
A Few Things People Get Wrong
One persistent myth is that tighter is better. Cranking down the slide adjuster until the tubing digs into the cheeks doesn’t improve the seal; the oxygen flows through the prongs sitting inside the nostrils, not through a mask-like face seal. Over-tightening just creates pressure points that lead to skin breakdown and discomfort, both of which cause people to remove the device more often.
Another misconception is that oxygen tubing should be kept as short as possible. While excess tubing can snag and pull, cutting it too short leaves no slack for normal movement, so you get yanked every time you turn your head. Most home setups come with generous lengths for a reason. The trick is managing the slack with a tubing clip on your clothing rather than eliminating it.
Finally, some people assume that if the cannula keeps falling off, they need a higher oxygen flow to compensate for the gaps. Increasing flow without a doctor’s order can dry out the nasal passages faster and, at higher rates, cause headaches and nosebleeds. The correct response to frequent dislodgement is to fix the securement, not to turn up the dial. If your prescribed flow rate doesn’t seem adequate even when the cannula is in place, that’s a separate clinical question for your provider.
