Definition
A physician trained in the diagnosis and treatment of conditions caused by changes in ambient pressure, including altitude-induced decompression sickness (DCS) and arterial gas embolism. Treatment is typically delivered in a hyperbaric chamber, where the patient breathes oxygen at pressures greater than sea-level atmospheric pressure to force nitrogen bubbles back into solution and resolve tissue injury.
Plain English
A doctor who specializes in treating illnesses caused by pressure changes, usually by putting the patient in a sealed chamber that simulates being deeper than sea level while they breathe oxygen.
Context Anchor
Seen in FAA guidance on altitude-induced decompression sickness, where a pilot may need medical evaluation after symptoms following high-altitude exposure.
Derivation
From the Greek 'hyper' meaning 'above' or 'beyond,' and 'baros' meaning 'weight' or 'pressure.' So 'hyperbaric' literally means 'above normal pressure' — pointing directly to the higher-than-sea-level pressures used in the treatment chamber.
Why Pilots Care
Prompt referral to this specialist can resolve decompression sickness symptoms, reduce risk of permanent neurological damage, and allow safe return to flying.
Grounding Statement
If a pilot feels unusual pain, dizziness, or other symptoms after high-altitude exposure, this is the kind of medical specialist who understands the pressure-related cause and treatment.
Intuition Check
Do not read “specialist” here as just any experienced pilot, instructor, or general first-aid provider. In this context, it means a medical professional specifically trained in pressure-related illness and treatment.
Example Sentence 1
After the pilot reported persistent joint pain and tingling following a high-altitude flight, the flight surgeon referred him to a hyperbaric medicine specialist for evaluation.
Example Sentence 2
Training materials note that a hyperbaric medicine specialist can administer the recompression treatment required for serious cases of the bends.
