Hyperbaric Oxygen Therapy in Colorado Springs: What the Clinical Evidence Shows
April 2026 · 12 min read
Hyperbaric oxygen therapy has been used in medicine for decades — but most people's exposure to it has been through vague wellness marketing or a friend who swears by it without being able to explain why. The actual science is more interesting than either the hype or the skepticism. At therapeutic pressures, HBOT triggers biological changes that no drug or supplement can replicate. This article walks through the mechanism and the clinical evidence, specifically as it applies to what we offer in Colorado Springs.
What Is Hyperbaric Oxygen Therapy?
Hyperbaric oxygen therapy means breathing pure (100%) oxygen inside a pressurized chamber at greater than normal atmospheric pressure. "Hyperbaric" literally means elevated pressure. At sea level, atmospheric pressure is 1 ATA (atmosphere absolute). Therapeutic HBOT runs at 1.5 to 3.0 ATA depending on the protocol.
At Colorado Springs Health Collective, we operate at 2.0 ATA — the pressure level used in every major RCT demonstrating meaningful clinical outcomes. This isn't a detail. Pressure determines oxygen delivery, and oxygen delivery determines what HBOT can actually do.
Under normal conditions, oxygen is carried almost entirely by red blood cells (hemoglobin). At 2.0 ATA breathing 100% O₂, oxygen also dissolves directly into blood plasma at concentrations 10–15 times higher than normal. That plasma-dissolved oxygen can reach tissues that red blood cells can't access — injured tissue, inflamed tissue, or tissue with compromised blood flow.
How HBOT Works: The Four Biological Mechanisms
Angiogenesis
HBOT stimulates the growth of new blood vessels (angiogenesis) by upregulating VEGF and other growth factors. More vessels mean better perfusion to previously oxygen-starved tissue — a permanent structural improvement, not a temporary effect.
Stem Cell Mobilization
A single 2.0 ATA session can mobilize stem cells from bone marrow into circulation by 800%. These circulating stem cells home to sites of injury and participate in tissue repair — a mechanism unavailable to any drug.
Inflammation Control
HBOT downregulates pro-inflammatory cytokines (TNF-α, IL-1β, IL-6) while preserving the acute inflammatory response needed for healing. The net effect is reduced chronic inflammation without immunosuppression.
Senescent Cell Clearance
Repeated HBOT sessions at 2.0 ATA trigger apoptosis in senescent cells (damaged 'zombie cells' that drive aging and inflammation) while simultaneously lengthening telomeres in immune cells — documented in peer-reviewed human trials.
Conditions & Clinical Evidence
The following evidence comes from peer-reviewed meta-analyses and RCTs. We present the numbers as they are — no hedging, no cherry-picking.
Wound Healing & Diabetic Ulcers
Cochrane review of 10 RCTs (531 patients). Major amputation rate drops from 26% to 10.7% in diabetic wounds. Skin graft survival: 97.7% with HBOT vs 92.3% conventional.
Sudden Hearing Loss
2025 meta-analysis of 16 RCTs (1,087 patients): 2.61× higher odds of clinically meaningful hearing recovery (95% CI 1.86–3.68, p < 0.001).
Fibromyalgia & Chronic Pain
Multiple clinical studies show 87.5–100% efficacy for pain relief. Also documented for autoimmune-associated skin ulcers in the same range.
Long COVID & Brain Fog
Retrospective analysis of 162 patients: 86% achieved clinically significant cognitive improvement after 40–60 sessions at 2.0 ATA.
Ulcerative Colitis
Blinded UC trial: 50% clinical remission in the HBOT group vs 0% in the control group.
Cellular Anti-Aging
Hachmo et al. (2020): 37% reduction in senescent cells and 20%+ telomere lengthening after a 60-session protocol at 2.0 ATA — the first non-pharmacological intervention to achieve this.
Why 2.0 ATA? The Pressure That Actually Works
The consumer wellness market has flooded with soft-shell "hyperbaric" chambers operating at 1.3 ATA. At 1.3 ATA breathing air (not pure O₂), the additional oxygen delivered to tissues is marginal — insufficient to trigger angiogenesis, stem cell mobilization, or senolytic effects.
Every published RCT showing the outcomes listed above used 2.0 ATA or higher with 100% oxygen. That is the minimum pressure required to dissolve oxygen into plasma at therapeutically meaningful concentrations. It's why we chose 2.0 ATA as our standard and why we won't offer lower-pressure alternatives that underdeliver.

What to Expect at a Session
No special preparation is needed. Avoid alcohol for 24 hours prior. Wear comfortable, loose-fitting clothes — we'll provide a 100% cotton gown to reduce static risk.
You'll lie inside the chamber as it pressurizes over about 10–15 minutes. At full pressure you breathe pure oxygen through a mask. Most patients watch a show, listen to music, or sleep. Sessions run 60–90 minutes at pressure.
Most people feel energized or pleasantly drowsy. Some report heightened mental clarity in the hours following a session. There's no downtime — you can drive yourself and return to normal activities immediately.
For therapeutic protocols, sessions are typically 5 days per week for 4–12 weeks. For maintenance and longevity, many patients transition to 1–3 sessions per week indefinitely.
Is HBOT Safe?
HBOT has decades of clinical use and an excellent safety record. The most common side effect is mild ear pressure during pressurization — similar to descending in an airplane — which resolves by equalizing (yawning, swallowing, or using the Valsalva maneuver).
Oxygen toxicity seizures are the most serious theoretical risk, but they are exceedingly rare at standard therapeutic pressures — occurring in fewer than 1 in 10,000 sessions in modern clinical settings. Temporary vision changes (mild myopia) occasionally occur with extended protocols and consistently reverse after treatment ends.
Contraindications include untreated pneumothorax, certain chemotherapy agents (bleomycin, doxorubicin), and severe COPD with CO₂ retention. All patients at CSHC complete a medical intake review before beginning any HBOT protocol.
Frequently Asked Questions
How many HBOT sessions do I need?
Most therapeutic protocols run 20–60 sessions depending on the condition. Wound healing typically requires 20–40 sessions, while cognitive and anti-aging protocols are often 40–60 sessions. Your provider will build a protocol specific to your goals.
Is hyperbaric oxygen therapy covered by insurance?
Insurance covers HBOT for a narrow list of FDA-approved indications (wound healing, decompression sickness, carbon monoxide poisoning, etc.). For longevity, Long COVID, and off-label use, sessions are typically out-of-pocket. Founding member pricing at CSHC is structured to make this accessible.
What does an HBOT session feel like?
Most patients describe it as relaxing — like lying in a reclined pod listening to music or watching something. You may feel mild pressure in your ears during pressurization, similar to descending in an airplane. The session runs 60–90 minutes at full pressure.
Is HBOT safe?
HBOT has an outstanding safety record. The most common side effects are mild ear pressure and, rarely, temporary vision changes (which resolve after treatment ends). Oxygen toxicity seizures are exceptionally rare at standard therapeutic pressures (< 1 in 10,000 sessions). Contraindications include untreated pneumothorax and certain chemotherapy agents.
What makes 2.0 ATA different from lower-pressure options?
Pressure is what drives oxygen into plasma and tissues. At 2.0 ATA you achieve 10–15× normal dissolved oxygen — enough to reach tissues with compromised blood flow. Consumer-grade soft-shell chambers operate at 1.3–1.5 ATA and deliver a fraction of the therapeutic benefit. All published RCTs showing meaningful results used 2.0 ATA or higher.
Can HBOT help with sports recovery?
Yes. HBOT accelerates clearing of lactic acid, reduces post-exercise inflammation, and promotes tissue repair. Elite athletes use HBOT between training blocks to recover faster and train harder. Several NFL and NBA teams use it regularly.
