About Us

The Ottawa Hospital’s Hyperbaric Medicine Unit is the only hospital-based hyperbaric unit in Eastern Ontario. Our dual-place chamber is used to provide both routine and emergency treatments.

Hyperbaric treatment is treatment under increased air pressure. This unique treatment is achieved by compressing the air in a special pressure-proof, cylindrical steel chamber. Our chamber is referred to as a dual place chamber. Two patients can be treated at one time.  Our unit is staffed with respiratory therapists and physicians. Hyperbaric oxygen treatment involves breathing 100% oxygen inside a hood while under increased pressure. Hyperbaric oxygen treatment is meant to complement other treatment modalities, such as surgery, antibiotic therapy etc.
