INTRODUCTION
Mountaineers exposed to hypobaric hypoxia (HH) show high-altitude periodic breathing (PB).
OBJECTIVE
To analyze high-altitude PB during the ascent of Mount Aconcagua (Argentina).
MATERIALS AND METHODS
Descriptive study in healthy volunteers using respiratory polygraphy (RP) at different altitudes.
RESULTS
We studied 8 andinist, mean age: 36 years old (25-51), body mass index (BMI) of 23.6 (20.9-28.7) and 22.77 (20.9-27.7) upon return, <0.01. RP without PB showed a lower Oxygen Desaturation Index (ODI) and a lower Apnea-Hypopnea-Index (AHI); 5.43 (0 - 20) versus 45.95 (2-122) <0.001 and 3.9 (0-15.5) versus 44.35 (4-115) <0.001. AHI increased with altitude at the expense of central apneas and hypopneas: <0.05.
CONCLUSION
High-altitude PB is frequent above 2,581m.a.s.l. And it is characterized by short cycles. None of the mountaineers showed PB at baseline; however, high-altitude PB occurred in all subjects above 4,900 m.a.s.l.
引言
暴露于低压缺氧环境的登山者会出现高原周期性呼吸（PB）。
目的
分析攀登阿空加瓜山（阿根廷）过程中的高原PB。
材料与方法
对健康志愿者进行描述性研究，在不同海拔高度使用呼吸多导仪（RP）。
结果
我们研究了8名登山者，平均年龄：36岁（25 - 51岁），返回时体重指数（BMI）为23.6（20.9 - 28.7）和22.77（20.9 - 27.7），P<0.01。无PB的RP显示较低的氧去饱和指数（ODI）和较低的呼吸暂停低通气指数（AHI）；分别为5.43（0 - 20）对45.95（2 - 122），P<0.001以及3.9（0 - 15.5）对44.35（4 - 115），P<0.001。AHI随海拔升高而增加，以中枢性呼吸暂停和低通气为代价：P<0.05。
结论
海拔高于2581米时高原PB很常见，且周期较短。所有登山者在基线时均未出现PB；然而，海拔高于4900米时所有受试者均出现了高原PB。
