Hyperbaric Oxygen Therapy (HBOT) can help you reach new heights in health, naturally, using 100% pure oxygen.
Not all equipment is created equal. No zip-up HBOT at Rainier Hyperbaric. Rainier Hyperbaric offers state of the art Sechrist hard shell monoplace chambers for individualized hyperbaric oxygen therapy sessions to increase the body’s ability to fight infections and improve the rate of healing.
This noninvasive and painless treatment can help those who suffer from chronic illness, injuries, infection, PTSD, and catastrophic events such as strokes or brain injuries. HBOT treatments involve increasing the atmospheric pressure in 100% pure oxygen inside a pressurized chamber. Tissues become saturated with oxygen, which promotes healing that cannot be achieved with any other therapy.
A typical series includes 60-minute sessions, 4-5 days per week for a minimum of 30 days. Depending on the severity of the issue and the body’s response to HBOT, the treatment period may be longer.
Visit our About HBOT page to read how HBOT is used to treat various debilitating injuries and conditions.

My wound from a total knee replacement is healing much faster than expected.Posted on Lenna ShepardDecember 22, 2025Trustindex verifies that the original source of the review is Google. customer service is amazingPosted on Murray RosenthalNovember 6, 2025Trustindex verifies that the original source of the review is Google. We’ve been going sometime now. This is one of the most under appreciated treatments in medicine. Ranier has first class chambers and a professional environment. Highly recommendPosted on Lori WakefieldOctober 30, 2025Trustindex verifies that the original source of the review is Google. I always feel so much better after my visits. Hbot was invaluable for feeling well enough to finish my chemo treatments. Michelle is so wonderful, and Trisa has always been very accommodating!Posted on Matthew & Whitney CoxMarch 22, 2025Trustindex verifies that the original source of the review is Google. Ive been coming to Rainier Hyperbaric for a month. I got a concussion from a car wreck. After 8 months of healing I couldn’t shake the brain fog and headache. Since I’ve done 25 sessions (I hit it really hard) my headache is almost gone, the fog has almost lifted, and I feel the most like myself since the accident 8mo ago. Trisa, and the staff have been absolutely great. I am super thankful that hyperbaric has worked so well.Posted on Terri ArcieriMarch 21, 2025Trustindex verifies that the original source of the review is Google. I booked 10 sessions hyperbaric O2 chambers because I had ringing in the ears and sudden hearing loss. I just came back from the Audiologist and I have a big improvement in my hearing and the ringing has quieted down and is sometimes not even noticeable. I am so grateful I hope I continue to see improvement.Posted on diana umetsuMarch 7, 2025Trustindex verifies that the original source of the review is Google. I came here after being recommended by a friend who had treatment here after surgery. It was definitely worth the drive from Snohomish. I wanted this to help with healing after having Fractional c02 laser treatment. I did 4 sessions in 3 days. My healing process was so much quicker and less painful due to the hyperbaric. I definitely will return here. The staff here is amazing! The owner, Trisa, is the best! She truely cares about the people who come here and what she does. The people here make sure you are totally comfortable at every stage of the process. The staff made sure I understood the process and thoroughly answered all my questions. I highly recommend!!!Posted on Andrew ParryNovember 17, 2024Trustindex verifies that the original source of the review is Google. After doing quite a bit of research I decided to bring my mom in to begin a 20 round visit at 2.0 Atm of pressure. Each session lasted an hour. These treatments were spread out over six weeks, some weeks having four visits and others having three. She had some inner ear issues previously that had been corrected. We came in concerned that inner ear discomfort might be an issue. The staff on hand were very knowledgeable and considerate about our concern with this ear issue. We started slowly and raised pressure incrementally, after 5 or 6 visits things were pretty routine. We definitely noticed a huge difference in my moms aerobic capacity directly after treatments. We found that if we got her on an exercise bike following a HBOT session her time and resistance nearly tripled. We thought this gave her an excellent jumping off point to greatly increase her strength and circulation.Posted on Chelo AyarzagoitiaOctober 18, 2024Trustindex verifies that the original source of the review is Google. Literally the best hyperbaric I have tried!! I can immediately feel the difference when is a really good one. The chamber is very comfortable plus I love that is crystal so you don’t feel trapped. And at the end they give you a nice complimentary treatment to help get the best of the oxígen treatment. Excellent friendly service!!Posted on DGSeptember 17, 2024Trustindex verifies that the original source of the review is Google. This treatment has absolutely helped me more than I ever expected. I came for help with Autoimmune issues and Epstein Barr Virus, but experienced healing in a lingering sprained ankle, a frozen shoulder, and a dental procedure that never fully healed. I am so thankful for this treatment!
