Like a change in altitude
Your ears may feel full or pop, similar to an airplane flight. We coach you through gentle ear-clearing techniques, such as swallowing or yawning. You may notice some warmth and the sound of air entering the chamber.1

See the space for yourself
Sit upright. Stretch out.
Find your comfortable fit.
You do not have to lie flat throughout treatment. Every chamber we use has room to sit upright, and our team will help you get settled.
A chamber for one
Our single-patient chambers give you your own treatment space, with room to change position and get comfortable. Clinic-approved pillows and blankets are provided.
A walk-in chamber with extra room
Our multiplace chambers offer upright seating and a spacious interior. They are an option worth exploring if claustrophobia, anxiety, or a child's need for a caregiver is on your mind.
Nervous? Start with a look inside. Tell us before your visit. We can show you the chamber, explain how you stay in contact with your technician, and discuss the best fit for your needs. Let us know about any mobility or transfer assistance you require.
From hello to your first session
We walk you through every step.
You do not need any experience with hyperbaric oxygen therapy. That is what your team is here for.
-
Meet your team
We review your history, goals, and questions. A licensed medical provider determines whether HBOT is appropriate and prescribes your treatment plan.
-
Get ready together
We complete your pre-treatment checks, review clothing and personal items, and show you how to equalize your ears and communicate with your technician.
-
Settle into your chamber
Get comfortable while we fit your oxygen mask or hood. Our chambers are pressurized with air; you breathe medical-grade oxygen through your breathing system.
-
Relax, then check in
Your team monitors you throughout treatment, returns the chamber to normal pressure, and checks how you feel before you head out.
Make time for an unhurried first visit. Treatment options commonly include 60- or 90-minute sessions. Allow additional time for check-in, preparation, and pressure changes. We will confirm the total appointment time when you book.
What treatment feels like
A little ear pressure.
A lot of time to unwind.
Most of the pressure sensation happens as the chamber pressure changes at the beginning and end. The main part of your session is time to settle in and rest.
Your time to relax
Once your ears have adjusted, there is usually little ongoing pressure sensation. Breathe normally through your oxygen system. Many patients rest, read clinic-approved material, or fall asleep. Your technician guides any prescribed air breaks.
A gradual return
We slowly bring the chamber back to normal pressure. Your ears may pop again, and the air can feel cooler. Your technician lets you know when it is time to get ready to exit.
Treatment should not be painful. Tell your technician immediately about ear pain, discomfort, or anxiety. We can slow or pause the pressure change and help you. You should never try to push through pain.
After your first treatment
You may notice a difference.
Healing has its own pace.
Early changes can be encouraging.
Some of our patients report feeling more relaxed, having less pain, or noticing reduced swelling after their first session. Others notice changes gradually over a series of treatments. Your experience depends on your condition and individual response.
A first-session improvement is possible, but it is not a promise. Not feeling an immediate change does not, by itself, tell us whether treatment is helping. We follow your symptoms and the goals in your care plan over time.
For many patients, one treatment is the beginning of a prescribed course. Tell us what you notice so your provider can assess your progress. You may also feel temporarily tired or hungry afterward.1
22 years of care in the Valley
Confidence starts with the people beside you.
As a premier hyperbaric facility in the Valley, RX-O2 brings medical oversight, experienced technicians, and thoughtful preparation to every visit.
Physician-led care
A licensed medical provider reviews your suitability, discusses benefits and risks, and prescribes your treatment. We take time to understand your needs before you enter the chamber.
Safety taught here
RX-O2 is the Valley's only hyperbaric teaching facility for the National Hyperbaric Safety Association. Our NHSA-certified technicians train in chamber operation, patient monitoring, and emergency procedures.
Attention throughout
We use FDA-cleared hard-shell chambers and follow chamber safety procedures, including screening what goes inside. Your team monitors you throughout the session and stays available to communicate.2
A reassuring start for families
The Valley's only pediatric hyperbaric facility.
Children deserve a gentle introduction, too. We explain the chamber in age-appropriate terms, help with ear equalization, and plan for a parent or caregiver to accompany the child. The accompanying adult also needs screening and clearance. Tell us about sensory concerns or support needs when you schedule.
A little preparation goes a long way
Come comfortable. We will handle the details.
Before you arrive
- Wear clean, comfortable cotton clothing. Follow the clothing instructions we provide. All clothing and items entering the chamber must pass our safety check.
- Bring your questions and medication list. Tell us about changes in your health, recent procedures, or new prescriptions.
- Call if you are unwell. Fever, congestion, or new ear or sinus symptoms may mean we need to reschedule.
- Ask about a book. You may bring reading material for our team to review. We also have clinic reading options and approved blankets and pillows.
Keep these outside the chamber
- No electronics or battery-powered devices. Phones, smartwatches, earbuds, tablets, and electronic toys are not allowed inside.
- No flammable items. Lighters, matches, vaping devices, and warming devices must stay outside.
- Skip lotions, oils, makeup, and petroleum products. Follow our preparation instructions and ask us about any prescribed topical treatment.
- Have every item checked. Personal blankets, toys, bottles, and other belongings require review before entry. If you are unsure, ask your technician.
Use a medical device or special dressing? Tell us before your appointment about implants, insulin pumps, glucose monitors, hearing aids, or wound dressings. Do not remove or change a prescribed device on your own. Our team will coordinate safe arrangements.

It is okay to ask
A few things you may be wondering.
Whether your question feels big or small, we want you to feel informed before you begin.
What if I am claustrophobic?
Tell us when you schedule. We can show you the chamber before treatment, explain the communication system, and discuss our larger walk-in option. Chamber selection depends on your medical needs and availability. You do not need to hide your concerns or rush your decision.
Can I talk to someone during treatment?
Yes. We show you how to communicate with your technician before the session begins. Our team monitors you throughout treatment. You are not left to manage the chamber or your treatment on your own.
What if I need to stop?
Tell your technician. We will guide the chamber safely back to normal pressure before opening the door. Exiting takes time because pressure must be reduced safely. We explain this process before your first session so you know what to expect.
Can I sleep, read, or bring my phone?
Many patients rest or sleep once comfortably at treatment pressure, and reading material may be allowed after our safety check. Stay attentive to your technician during pressure changes and follow their instructions. Phones and all other personal electronics or battery-powered devices must remain outside the chamber.
Can my child have a parent or caregiver inside?
Yes. Pediatric treatments are planned with an accompanying parent or caregiver. Both the child and accompanying adult require appropriate screening and clearance. We will arrange the chamber and preparation around their needs.
Is hyperbaric oxygen therapy safe?
HBOT is generally well tolerated when appropriately prescribed and supervised, but it has risks. These include ear or sinus injury, temporary vision changes, and, less commonly, oxygen toxicity or lung injury. Oxygen also increases fire risk, which is why chamber rules matter. Your provider reviews your health history and personal risks before prescribing treatment.1, 2
