Brief summary

Hyperbaric oxygen is the provision of oxygen in a compression chamber.The aim of this trial is to test the hypothesis that hyperbaric oxygen treatment (HBOT) may improve symptoms in people with Long-COVID . We will compare symptoms of those allocated to the HBOT to participants allocated to no HBOT.

Interventions

The treatment is hyperbaric oxygen daily for 10 days (mon to Friday) for 90 mins at 2.4 ATA (atmospheres absolute). This is a commonly used treatment table known as a US Navy Table 14 ( USNTable 14). The period may be over more than two weeks if the participant has any intercurrent illness which prevents ear equalisation and requires deferment. Oxygen is given in a multiplace chamber by TGA approved hoods or masks depending on participant preference and comfort of fit. They sit in an easy reclin

Oxygen is given in a multiplace chamber by TGA approved hoods or masks depending on participant preference and comfort of fit. They sit in an easy recliner for the duration of treatment. The treatment is given by certified Hyperbaric physicians in an accredited hyperbaric facility under the oversight of a Senior ANZCA accredited Hyperbaric Physician and Anaesthetist.
