Field notes

HBOT knowledge base

Hyperbaric oxygen therapy explained: what pressure does, how long a protocol runs, and where the evidence stops. Written inside the clinic, sourced to the research.

HBOT for athletic recovery: what the bone and joint evidence supports

Thirty sessions against a pressure-matched sham eased pain in early femoral head necrosis, and none of the 20 patients needed a hip replacement seven years later. Training soreness is the exception.

Hyperbaric oxygen for wound healing: which wounds respond

4 September 2026 · Research

One randomized trial closed 52% of chronic diabetic foot ulcers against 29% on placebo. Two later trials found nothing. What separates them is whether the wound was short of oxygen in the first place.

Does HBOT help long COVID? What separates the three trials is dose

19 August 2026 · Research

Three sham-controlled trials, one clearly positive. The trial that ran 40 sessions found moderate gains in cognition, energy, sleep and pain. The two that stopped at ten found nothing.

What actually happens to inflammation under pressure

27 July 2026 · Research

Hyperbaric oxygen is often described as anti-inflammatory. The truth is more precise, and more interesting. A short primer on the pathway.

Why 2.0 ATA changes what oxygen can do in the body

12 July 2026 · Research

At sea level, plasma carries very little dissolved oxygen. Under pressure, the physics shift and tissues that were starved suddenly have supply. Here is what that means for recovery.

Red light before hyperbaric oxygen: a stackable protocol

24 June 2026 · Protocols

Five minutes of NASA-grade red light before the chamber primes mitochondria. We look at the mechanism and the practical why behind the sequence.

Cognitive fog, TBI and the case for repeated exposure

9 June 2026 · Cognitive

One session is an experience. Twenty is a protocol. We collect the current literature on cumulative dose for cognitive recovery.
