Clinical hyperbaric O2
treatment schedules.
A, The patient breathes 100% O2
for 2
hours at an ambient pressure of 2 ATA. Generally, this schedule is used for repetitive
treatment of chronic conditions (e.g., osteoradionecrosis). B,
Therapeutic schedule for the treatment of clostridial myonecrosis. The patient spends
85 minutes at an ambient pressure of 3.06 ATA and breathes 100% O2
, with
the exception of two 5-minute air breaks to minimize pulmonary and central nervous
system O2
toxicity. A decompression stop is made at 1.3 ATA, according
to the U.S. Navy standard air decompression table. This decompression stop is designed
to prevent decompression sickness in the tenders, who breathe air throughout the
period at 3.06 ATA.
