Lung function and blood gas of rats after different protocols of hypobaric exposure.
High-altitude pulmonary edema (HAPE) is a common disease observed in climbers, skiers and soldiers who ascend to high altitudes without previous acclimatization. Thus, a reliable and reproducible animal model that can mimic the mechanisms of pathophysiologic response in humans is crucial for successful investigations. Our results showed that exposure to 4500 m for 2 days had little influence on lung function or blood gas, and exposure to 6000 m for 2 or 3 days could change lung function and blood gas, but most parameters returned to nearly normal levels within 48 hours. This study indicates that exposure to 6000 m for 3 days may induce evident lung edema and significantly alter lung function and blood gas, which may mimic HAPE in clinical practice. Thus, this animal model of HAPE may be used in future studies on HAPE.
期刊介绍：
Medical Gas Research is an open access journal which publishes basic, translational, and clinical research focusing on the neurobiology as well as multidisciplinary aspects of medical gas research and their applications to related disorders. The journal covers all areas of medical gas research, but also has several special sections. Authors can submit directly to these sections, whose peer-review process is overseen by our distinguished Section Editors: Inert gases - Edited by Xuejun Sun and Mark Coburn, Gasotransmitters - Edited by Atsunori Nakao and John Calvert, Oxygen and diving medicine - Edited by Daniel Rossignol and Ke Jian Liu, Anesthetic gases - Edited by Richard Applegate and Zhongcong Xie, Medical gas in other fields of biology - Edited by John Zhang. Medical gas is a large family including oxygen, hydrogen, carbon monoxide, carbon dioxide, nitrogen, xenon, hydrogen sulfide, nitrous oxide, carbon disulfide, argon, helium and other noble gases. These medical gases are used in multiple fields of clinical practice and basic science research including anesthesiology, hyperbaric oxygen medicine, diving medicine, internal medicine, emergency medicine, surgery, and many basic sciences disciplines such as physiology, pharmacology, biochemistry, microbiology and neurosciences. Due to the unique nature of medical gas practice, Medical Gas Research will serve as an information platform for educational and technological advances in the field of medical gas.
