The hyperbaric oxygen (HBO2) treatment was applied with initial compression to 2.8 atmospheres absolute (ATA) and 100% O2 administered for 45 minutes. After 45 minutes at 2.8 ATA, injuries were decompressed to 2.0 ATA within 5 minutes and given a 5-minute air break (no oxygen). After the air break, patients were treated at 2.0 ATA for 55 minutes, after which the protocol was terminated. PT, patient; OPT, optional.
