Resident keeps pulling off their oxygen: what to do when they refuse

A CNA on r/cna posted this:

"

I've got a resident on 2L NC and she WILL NOT keep it on. I've put it back on probably 30 times tonight. She says it's annoying, it hurts her ears, it dries her nose out, she doesn't need it. The nurse is mad at me because her sats keep dropping into the 80s every time I leave the room. I can't stand in her room all shift and force her to wear it. What am I supposed to do?

This post got 412 upvotes and 180 comments. It's one of the most common oxygen-related frustrations in SNF and LTC work, and the answer is more nuanced than "just keep putting it back on."

What's actually going on

Residents remove supplemental oxygen for real, physical reasons. Most of the time it's not defiance.

It hurts. The cannula tubing digs into the cheekbones and ears. After a few hours, that becomes a constant pressure sore, especially on elderly skin. The elastic strap on a face mask pulls at the back of the head. If the resident has any facial swelling, post-surgical dressing, or dental work, the pressure is worse.

It dries them out. A 2L nasal cannula blows dry medical air directly across the nasal mucosa. Within hours, residents get nosebleeds, cracked lips, sore throat, and a feeling of being unable to clear their sinuses. Once that starts, the mask or cannula becomes associated with pain.

It's claustrophobic. A simple nasal cannula is one thing. A non-rebreather, a BiPAP, or a high-flow mask covers most of the face. For a resident who is cognitively intact, that's an ongoing assault on their sense of control. For a resident with dementia, it can be terrifying — they don't understand why this thing is on their face, and they pull it off because it doesn't belong there.

It doesn't feel like it's doing anything. If the resident is short of breath at rest, they perceive the oxygen as helpful. If they're not, the cannula feels like an unnecessary nuisance. From the resident's perspective, they're not refusing care — they're refusing something that has no obvious benefit.

It's a control thing. Like the constant call-light problem, oxygen is one of the few things a resident can physically remove and control. In an environment where meals, medications, bath schedules, and even bathroom trips are scheduled by someone else, taking the cannula off is agency.

Knowing which of these applies to your resident changes what helps.

What usually doesn't work

The first instinct — and the one most nurses will push you toward — is to keep putting it back on. Every time you walk past the room, glance in. If it's off, put it on. Walk away. Find it off again. Repeat for 8 hours.

This fails for predictable reasons:

• It doesn't address why the resident is removing it. They will keep removing it.
• It escalates the resident's frustration. Within a shift, you have an anxious, angry resident and a frustrated CNA.
• It puts you in the position of forcing a medical device onto someone who is competent to refuse it, which is a real legal and ethical issue.

The second instinct — telling the resident they'll die without it — is worse. It's not accurate at 2L for most residents, it scares them, and it damages the trust you need to actually help.

What tends to work

1. Fix the comfort problem first.

If the tubing is digging into their ears, switch to a nasal cannula with ear cushions, or pad the tubing with a 2x2 gauze square behind each ear. If their nose is dry, ask the nurse about saline nasal spray or a humidifier bottle on the flowmeter. If the strap is too tight, adjust it. These are small things, but they are the difference between a resident who tolerates the cannula and a resident who pulls it off every 15 minutes.

2. Address the dryness.

A lot of cannula-removal is really nosebleed-prevention. Apply a thin layer of water-based lubricant (NOT petroleum — petroleum and oxygen are a fire risk) to the lips and around the nares if the facility protocol allows it. Offer warm fluids if diet permits. These aren't in your scope to order, but you can absolutely suggest them to the nurse.

3. Reassess the order.

A resident who is consistently removing oxygen and sats are borderline is a candidate for the order itself to change. Lower flow, intermittent versus continuous, a different delivery method — these are nursing and provider decisions, not yours. But you can be the one who flags the pattern. "Resident has removed cannula 28 times this shift, sats are 86% without it, 92% with it, she complains of ear pain and dry nose" is data. That data goes to the nurse.

4. Distraction and timing.

For residents with mild cognitive impairment, the cannula comes off because they forgot it was on, or because something else is more interesting in the room. Engaging them — a conversation, a TV show, a visit, an activity — gets hours of compliance without a single reminder. For residents who are sundowning, oxygen compliance often drops at the same time as confusion rises; planning your rounding to match that is more efficient than chasing them.

5. Reframe it.

"I need you to wear this forever" is a fight you will lose. "Wear this for the next hour while we eat lunch and visit with your daughter" is a smaller, more concrete ask. A resident who is anxious about oxygen is often anxious about what oxygen means — that they're sicker, that they're not going home, that they're dying. Sitting with that conversation (and bringing the nurse or social worker in for the deeper parts) sometimes does more than any number of tubing adjustments.

What to document

Every time the resident removes the oxygen and you put it back, document:

• The time you found it off
• The saturation at that moment (or "unable to obtain — refused")
• What the resident said about why
• What you did (replaced cannula, padded tubing, offered fluids, notified nurse)
• The saturation after replacement

This matters for three reasons. First, it's the data the team uses to decide whether the oxygen order is right, whether the delivery method needs to change, or whether the goals of care conversation needs to happen. Second, if the resident develops a complication from hypoxia — confusion, falls, cardiac event — your documentation shows you were monitoring and intervening. Third, if the family asks why mom's sats were low all night, your charting is the answer.

If the resident is genuinely refusing and is competent to refuse, document that too. "Resident A&O x3, states she understands she has been recommended to wear oxygen continuously, refuses, oxygen left at bedside" is a defensible note. Forcing it on a competent refuser is assault.

What NOT to do

• Don't physically restrain the cannula on the resident's face. Taping it down, tying the strap so tight they can't remove it, or blocking their hands is not in your scope and is a serious incident.
• Don't argue with the resident in front of their roommate or family. Pull them aside, or come back.
• Don't hide the fact that they're removing it from the nurse. "Sats are fine because I just put it back on" reads very differently two hours later when the resident is found unresponsive.
• Don't promise the resident the oxygen will come off "in a few minutes" if you have no authority to make that call. They will trust you less next time.

The hard truth

Some residents will not keep oxygen on, regardless of what you do. They have dementia, they have anxiety, they have a facial structure where the cannula doesn't fit, they have a right to refuse. You cannot fix this on your own. Your job is to:

• Make the device as tolerable as possible
• Document the pattern honestly
• Surface the pattern to the nurse so the order and the care plan can be adjusted
• Accept that for some residents, intermittent hypoxia on 2L is an acceptable risk compared to the agitation of forced compliance

If the resident's refusals are causing their sats to drop into dangerous territory every shift and the nurse and provider aren't responding, escalate. Charge nurse, then DON. If the facility won't engage, that's a staffing and care-plan issue, not a personal-failure issue. You've done your job if you've assessed, intervened, documented, and escalated.
