Two things sold for the same problem
Oxygen Therapy vs IV Hydration in Denver
If you arrive in Denver feeling unwell, two services will find you quickly: oxygen — in bars, cans and delivered concentrators — and IV hydration. They're marketed for the same complaint and they do entirely different things, and neither does what most of the advertising implies.
Here's the honest comparison, including where our own service falls short.
What oxygen actually does
Altitude symptoms are caused by lower oxygen pressure. Supplemental oxygen addresses that directly, which makes it the most physiologically targeted option available — and it's what hospitals use for genuine altitude illness.
The caveat is the size of the word while. Oxygen helps while you're breathing it. Take the cannula off and your blood oxygen returns to whatever your body can manage at 5,280 feet. It relieves symptoms; it does not acclimatize you.
There's also a real clinical risk in casual use: oxygen can mask worsening illness. If someone needs oxygen to feel functional at altitude, that's a signal to rest and descend — not a signal to carry on with the itinerary feeling fine.
What an oxygen bar is (and isn't)
Oxygen bars sell short sessions of scented, concentrated oxygen — recreational, not medical. They're not staffed by clinicians, they don't assess you, and the flavourings are cosmetic.
If you enjoy it, no harm done. But it isn't treatment, it isn't prevention, and it shouldn't change any decision you make about ascending or resting. Medical oxygen — prescribed concentrators, hospital delivery — is a completely different thing with completely different oversight.
What IV hydration does
An IV replaces fluid and electrolytes directly. Dehydration is a genuine contributor to feeling terrible at altitude: dry air, faster breathing, a long flight and a couple of drinks add up quickly, and dehydration symptoms overlap almost perfectly with altitude symptoms.
So an IV can make you feel substantially better — when dehydration is actually part of your problem. If you're vomiting or can't drink enough to keep up, it works faster than sipping.
What it does not do is address the oxygen deficit. Fluids don't change how much oxygen crosses into your blood. An IV is not an acclimatization treatment, and it is not preventive.
Side by side
| Supplemental oxygen | IV hydration | |
|---|---|---|
| Targets | Low blood oxygen | Dehydration & electrolytes |
| Speed | Minutes | 30–60 minutes |
| Lasts | Only while breathing it | Hours to a day |
| Treats the cause of altitude sickness? | Addresses it temporarily | No |
| Speeds acclimatization? | No | No |
| Best for | Symptom relief; medical altitude illness | Vomiting, can't keep fluids down, clear dehydration |
| Main risk | Masking illness that needs descent | Paying for something rest and water would fix |
| Offered by Intravene | No | Yes |
What neither of them fixes
Both are symptom management. Neither shortens the physiological process of adjusting to elevation, and neither is a reason to continue ascending when you feel unwell.
The things that actually resolve altitude sickness are unchanged and unsellable:
- Stop ascending.
- Rest — a genuinely easy day or two.
- Time — 24 to 72 hours for most people.
- Descend if you're not improving. Universally effective, and the only treatment that always works.
If a service implies it can replace those, that's marketing. Detail: How to Avoid Altitude Sickness in Denver
Our position, stated plainly
Intravene does not provide supplemental oxygen. We offer mobile IV hydration in Denver, and we think it's worth your money in a narrow set of circumstances: you're vomiting, you can't drink enough, or you're clearly dehydrated and losing a day to it.
If your symptoms are severe enough that you're wondering about oxygen, the honest answer is that you need medical assessment or a lower elevation — not a service call from us.
Go to an emergency room or call 911 for: breathlessness at rest · confusion or trouble walking straight · a cough with frothy or pink sputum · blue or grey lips · oxygen saturation persistently below 88–90%.

Frequently asked questions
Do oxygen bars help with altitude sickness?
They may make you feel briefly better while you're using one. They don't prevent altitude sickness, don't speed acclimatization, and shouldn't influence whether you rest or ascend.
Is oxygen better than an IV for altitude sickness?
For the oxygen deficit itself, yes — oxygen targets the actual mechanism. For dehydration and vomiting, an IV is the right tool. They solve different problems, and most people at Denver's elevation need neither.
Can I buy canned oxygen in Denver?
Yes, widely — convenience stores, outdoor shops, dispensaries. It's a small amount of oxygen, and the same caveat applies: temporary relief, no acclimatization, and don't let it talk you into going higher.
Does Intravene provide oxygen?
No. If you need oxygen, you need medical evaluation or descent.
Should I rent an oxygen concentrator for a Colorado ski trip?
For most healthy visitors this isn't necessary. For people with significant heart or lung conditions, or a history of high-altitude pulmonary edema, it's a conversation to have with your own physician before travelling. ---
