急进高海拔地区血氧饱和度和心率变化的研究
Research of raccelerated plateau on the change of blood oxygen saturation and heart rate
摘要
Abstract
Objective To investigate the changes of blood oxygen saturation and heart rate after urgently going to high‐alti‐tude area ,so as to provide a reference for medical rescue in high‐altitude area .Methods Subjects left from the plain area with an al‐titude of 400 m .Blood oxygen saturation and heart rate were measured before departure and after reaching 4 300 m altitude region . Then the subjects were taken to the destination with an altitude of 3 200 m ,at which they received a dynamic continuous monitoring of blood oxygen saturation /heart rate at the 1st day ,2nd day ,3rd day ,4th day ,5th day ,6th day ,7th day after arrival .After adapting to the environment in 3 200 m altitude area for 1 week ,subjects were taken to the 4 300 m altitude region ,at which they were re‐measured blood oxygen saturation and heart rate .Results After entering the areas of 4 300 m altitude and 3 200 m altitude ,the blood oxygen saturation was significantly decreased compared with that in plain area (P< 0 .05) .The blood oxygen saturation at the 6th and 7th day after entering 3 200 m altitude area was statistically different when compared with that at the 1st day(P< 0 .05) . The blood oxygen saturation had statistical difference between reaching at 4 300 m altitude area for the first time and re‐entering 4 300 m altitude area ,while the heart rate had no statistical difference (P> 0 .05) .Conclusion The arterial oxygen saturation was de‐creased with the increase of altitude ;the people living in plain areas can preliminarily adapt to the environment at 6th day after reaching 3 200 m altitude regions ;people can better adapt to the high‐altitude environment by shortly living in lower‐altitude areas before re‐entering high‐altitude areas .关键词
