What Researchers Did
Researchers conducted a prospective, controlled study in rabbits and adult human volunteers at varying altitudes to validate a new plateau hyperbaric chamber for alleviating high altitude hypoxia.
What They Found
In rabbits, mean PaO2 significantly increased from 49.6 ± 1.9 mmHg to 70.3 ± 2.1 mmHg (P < 0.01) after hyperbaric treatment. Similarly, in human volunteers, mean PaO2 rose from 51.2 ± 2.3 mmHg to 71.5 ± 2.5 mmHg (P < 0.01), accompanied by significant decreases in respiratory rate, heart rate, and blood pressure (P < 0.01).
Canadian Relevance

Study Limitations
The abstract does not explicitly state limitations, but the study involved a specific population and environment, and the long-term efficacy was not assessed.
