An enclosed space or tube that accommodates a patient and subjects the patient to ambient gas pressures >1 atm.
Chamber in which the oxygen pressure is higher than in the atmosphere; used to treat carbon monoxide poisoning, diving accidents, burns, infections (particularly gas gangrene), and certain breathing disorders.
An airtight enclosure strong enough to withstand high internal pressure. It is used to expose animals, humans, or an entire surgical team to increased air pressure.
An enclosed chamber where atmospheric pressure is methodically elevated and subsequently decreased, facilitating the reduction in size of nitrogen bubbles and the safe diffusion of nitrogen out of bodily tissues.
