What is the recommended pressure range for hyperbaric oxygen therapy treatment?

The recommended pressure range for hyperbaric oxygen therapy (HBOT) is indeed generally between 1.5 to 3.0 atmospheres absolute (ATA). This range is considered optimal for therapeutic effects, providing sufficient oxygen delivery to tissues for conditions that benefit from hyperbaric treatment, such as decompression sickness, carbon monoxide poisoning, and chronic non-healing wounds.

At pressures below 1.5 ATA, the oxygen delivery to tissues may not be adequate for the enhanced therapeutic benefits sought in HBOT. Conversely, while pressures above 3.0 ATA may provide some increased oxygen absorption, they also increase the risk of oxygen toxicity and complications, which can negate the therapeutic benefits. This is why the range of 1.5 to 3.0 ATA strikes a balance between effective treatment and safety, making it the standard for various clinical applications of hyperbaric medicine.
