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.
We are excited to announce that Rainier Hyperbaric is now officially recognized as a Certified Woman Owned Business by the Washington State Office of Minority & Women’s Business Enterprises

Adding Hyperbaric to my healing process has sped up my recovery time by at least half!! There new chambers are so much roomier and the atmosphere they have created at Rainier Hyoerbaric is 5 star. I would recommend this to anyone going through a healing journey! 🩷Posted on Lenna ShepardDecember 31, 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.
